ABSTRACT
This paper provides new evidence of late trading activities in the mutual fund markets of France, Germany and the Netherlands. We find that investors who are allowed to trade late can earn substantial returns between 22% and 47% annually. Evidence of such illicit and abusive trading practices was uncovered in 2003 during a large scandal in the US fund industry. Our preliminary findings suggest that late trading may still persist in European markets.
I. Introduction
The tip-off from a whistle blower in 2003 unfolded what became the largest scandal
in mutual fund history. As it turned out, several major asset management companies,
hedge funds and brokerage firms in the US engaged in abusive trading activities
including market timing, rapid trading, mispricing, insider trading and late trading. The
latter allows certain investors to trade mutual fund shares after market close, resulting
in profitable opportunities at the expense of other investors. This practice evolved from
the way mutual funds are priced. For example, US-based funds calculate their net asset
2
value per share (NAV) once a day usually at the close of the stock exchange at 4pm
Eastern Standard Time (EST). This is the price at which investors can purchase and
redeem fund shares. US statutory law requires trades in open-ended mutual fund shares
to be processed at a price following the order (forward pricing).1 Accordingly, orders
received before 4pm are executed at current day’s NAV, while orders received after
4pm must be executed at next day’s NAV. However, some investors were allowed to
place orders after 4pm at current day’s price (backward pricing). By doing so, these
investors could place orders after market close and profit by exploiting the likely
direction of the price movement the following day based on information revealed after
market close. Thus the exercise of stale price arbitrage provides an opportunity to
some investors to reap short-term gains at almost no extra risk to the detriment of long-
term (mainly small) investors.2 The additional expenses incurred by these trades are
shared by all investors at the fund level, while the profits are reserved for only those
who actually trade late. Zitzewitz (2006) estimates losses to late trading incurred by
long term investors at about USD 400m per annum.
Late trading was often facilitated by a brokerage firm or dealer which colluded with
investors. But fund companies have also allowed this practice for a fee or in exchange
for ‘sticky assets’ where investors engaged in late trading place additional funds into
other high fee investments under management. New York State Attorney General Eliot
Spitzer, who led the investigation into the mutual fund trading scandal in 2003,
compared such illegal trading schemes to “betting on a horse race after the horses
1 So called forward pricing rule 22c-1, adopted by SEC in 1968. 2 Late trading was often practiced together with market timing or frequent trading of mutual fund shares in an attempt to exploit stale prices. The rules surrounding market timing vary from fund to fund and such practice is either prohibited or deemed unethical since it violates the fund’s fiduciary duty to act in its shareholders’ best interests. In the words of former New York State Attorney General Eliot Spitzer “Allowing timing is like a casino saying that it prohibits loaded dice, but then allowing favored gamblers to use loaded dice, in return for a piece of the action.”

have crossed the finish line”.3 By the end of 2004, numerous institutions had settled
the alleged trading charges with payments totaling over USD 3bn.4 Settlements
included civil penalties, investor restitutions and lower future management fees.
Among those institutions were firms like Janus Capital Group, Franklin Templeton,
Bank of America, Bank One, Alliance Bernstein, Putnam, Old Mutual PLC, Sun Life
Financial, Canary Capital Partner LLC and many more. Since then, the fund industry
has grown from USD 16.2 trillion in assets under management in 2004 to USD 26.8
trillion in 2012, half of which is held by US funds.5 Almost every second household in
the US owns mutual funds either directly or indirectly.
In the wake of the US scandal, regulators in other countries became concerned
about potential misconduct in the fund industry of their own jurisdiction. For example,
the Committee of European Securities Regulators (CESR) conducted regulatory and
supervisory investigative work during the latter part of 2003 and in 2004 to assess the
state of affairs in the European fund industry.6 The investigation was mainly done by
sending out questionnaires to fund companies designed to detect possible malpractices
related to late trading and market timing. In some instances the investigation involved
on-site inspections or special audits. The investigation concluded that there was no
prima facie evidence of abusive trading practices in the member states, in spite of
some alarming findings in their report. Among others, compliance with cutoff times
used to determine whether an order gets processed at current or next day’s price could

not be verified in all cases, mainly due to inadequate record keeping.7 And this is
despite the fact that the cutoff time is clearly defined in the prospectus of all
investment funds according to the CESR report.
Also, poor organisational structures lacking clarity in responsibilities and
procedures were identified in a number of cases, with the ramification that can be
prone to trading abuses and business practices, e.g. “front running” favoring special
clients. Some fund managers even reported they had been approached by hedge funds
specifically asking for late trading or market timing facilities. Yet, the actions taken by
European regulators were relatively meager. Policies to hinder late trading or market
timing were largely implemented through self-regulatory codes of best practice in
cooperation with national fund industry associations. The upshot of all this was that
essentially fund companies had to do not much more than tighten their internal control
mechanisms.
In this paper, we examine the incidence and extent of late trading in Europe, the
second largest mutual fund industry in terms of assets under management after the US.
Our approach follows closely the methodology used by Zitzewitz (2006) for the US.
There are only a handful of academic studies addressing the alleged trading abuses and
associated consequences related to the 2003 US mutual fund scandal that resulted from
the discovery of illegal late trading and market-timing practices. For example,
Peterson (2010) and Frankel (2006-2007) evaluate the conditions and structures that
led to such trading abuses, mainly the regulatory environment in general and lack of
transparency. Houge and Wellman (2005) as well as Choi and Kahan (2007) examine
investor reactions by measuring capital flows, assets under management and fund
7 Such problems were identified as being somewhat alarming in France but not in Germany. The CESR review also identified problems of transparency (e.g. disclosure of fees and commissions to the investors) and some issues with trading systems (price making and trade with affiliated or third parties) in the case of Netherlands.

performance. Not surprisingly, funds that were involved in the investigation suffered
substantial outflows and underperformed their peers in the period following the
scandal. Shichor (2012) studies the scandal from a criminologist point of view. Davis,
Payne and McMahan (2007) assess the relationship between fund management fees
and control structures and illegal activities. They show that higher levels of
management fees decrease the likelihood of illegal behavior, most likely as a result of
reduced financial incentives to engage in malpractices.
However, there is no reason to believe late trading is an American phenomenon.
Using data from Morningstar allows testing for late trading globally across large
samples of mutual funds. We focus our study at the mutual funds markets of France,
Germany and the Netherlands. Our results show that net inflow into French mutual
funds is correlated with market movements after the market close of 5.30pm Central
European Time (CET) with some of the trades placed as late as between 8pm and
10pm CET.8 Similarly, net inflow into German equity funds with a cutoff time of
usually 3pm CET is correlated with futures price changes towards the end of trading
between 3pm and 5.30pm CET, as well as with changes in futures prices after market
close. However, in the case of German funds these correlations are negative which is
surprising as it suggests that the larger the hourly changes in future prices after the
cutoff time, the lower or more negative is the net inflow to the fund.
One explanation for this counterintuitive finding could be related to the use of net
inflow rather than capital in- or outflow data. Actual cash in- and out-flow would
obviously provide better insight, but such information is not readily available. The fact
that investors of German funds withdrew more capital than they invested over the
8 CET is one hour ahead of Coordinated Universal Time (UTC).
6
sample period might be an alternative explanation.9 Upon further analysis, we find that
such negative correlations are confined to days of large market swings around the
Global Financial Crisis (GFC) in 2008 and the deepening of the Sovereign Debt Crisis
(SDC) at the end of 2011. Thus, the results could also be driven by short sellers or late
traders maintaining a market neutral position during times of great uncertainty. Some
readers may object to this suggestion, but selling funds short was a common practice
among late traders that came to light during the US scandal in 2003.
Net inflow into Dutch mutual funds is also correlated with market movements after
4pm, the valuation or order processing cutoff time for most Dutch funds, as well as
with changes in future prices after market close. Overall, our evidence suggests that
cash flows into equity mutual funds are to some extent correlated with market
movements after the official cutoff times. And this is in spite the fact that the fund
industries were generally designated as ‘clean’ by the CESR investigation in 2004. On
the fund family level, we find that inflows are correlated with after hour price changes
in the future markets in 10% to 18% of fund families. This corresponds to the findings
reported for US domestic equity funds in Zitzewitz (2006).
This study also complements the literature on late trading by estimating the
potential gains from this practice. We find that investors who are allowed to trade late
can earn between 22% and 37% annually with a minimum number of illegal trades
following large market swings and as much as 47% per annum at the highest
frequency. These returns come with lower risk compared to a buy-and-hold strategy.
This result demonstrates why late trading has been so widespread and probably still is.
9 Average and cumulative daily net inflows across all funds are negative over the sample period. Average daily net inflow was negative USD 63k. In total more than USD 14.5bn was withdrawn from our sample funds.

The remainder of this paper is organized as follows. Section II describes the data.
Sections III and IV present the empirical findings. Section V suggests further work and
we conclude in section VI.
II. Data
We use daily net inflow and fund assets data from Morningstar. Net inflow is
estimated from a fund’s prior day assets, current day assets and the daily total return.
, 1(1 )it it i t itINFLOW TNA TNA r (1)
TNAit is a fund’s daily total net assets and rit is the fund’s total return. Hence, equation
(1) is simply the difference between current and prior day’s assets that is not accounted
for by daily total return. We obtain estimated share class inflow and net assets rather
than fund-level data in order to distinguish between retail and institutional investors.
This allows us to test whether certain investors are treated differently. For French
mutual funds the data is available from June 2006 until October 2013, for German
funds from June 2006 until August 2013 and for Dutch funds from August 2009 until
November 2013. Because of better data availability we restrict our sample to equity
mutual funds. We delete a small number of observations when inflow is more than
70% of prior day’s assets. In most cases this is associated with the inception of a fund.
To proxy for movements in the market we use changes in near-month future contracts
from Thomson Reuters Tick History (TRTH) obtained through Sirca. This enables us
to compute intraday price changes throughout and, perhaps more importantly, after
continuous trading in equities ends. We use changes in the price of future contracts on
the CAC 40 in the case of French funds and changes in the price of future contracts on
the DAX 30 and the AEX in the case of German and Dutch mutual funds, respectively.
These future contracts are traded every week day from 8am (for CAC) or 9am (for
DAX/AEX) until 10pm CET.

III. Empirical Results for Late Trading
In this section we use standard regression analysis to test for late trading.
Equation (2) is an example of a regression where the cutoff time for processing
redemption and subscription orders is assumed to be 12pm midday, while regular
trading in stocks ends at 5.30pm. This allows measuring the correlation of daily net
inflow with market movements after the official cutoff time and after market close as:
9 12 12 5:30 5:30 101 1 2 3
am pm pm pm pm pmit t t t itINFLOW FUT FUT FUT (2)
INFLOWit is the fund’s net inflow normalized by prior day net assets. The right-
hand side variables are log changes in the near-month future contract price. The first
term controls for market movements driven by information emerging before the cutoff
or valuation point. The other two terms capture post-cutoff information and hence late
trading. The end of futures trading is chosen to be 10pm since most future contracts in
Europe are not traded over night.10
Table 1 shows the results of different variants of equation (2) estimated for French
mutual funds that invest in domestic equities. The dependent variable is daily
normalized net inflow equally-weighted across funds. The legislation in France does
not specify a particular time at which fund shares are to be priced; rather each fund
company has to determine a valuation point in its prospectus. We have viewed
numerous fund documents and unlike the US, where funds price their shares usually at
4pm market close EST, cutoff time for most funds in France is around 12pm.11 Regular
trading hours for equities at the Euronext Paris are from 9am through 5.30pm, while 10 Note that 9pm was the latest trading time stated in the civil complaint brought in 2003 by the Attorney General of the State of New York to the State Supreme Court against Canary Capital Partners LLC, a hedge fund that collaborated with different brokers and asset management companies, including among others the Bank of America (Nations funds), to trade hundreds of funds late (after 4pm). 11 There are a few funds that deviate from this industry practice, but this has no effect on the results. All time designations in this section refer to CET unless otherwise stated.

future contracts on the CAC 40 are traded from 8am through 10pm. Therefore, our first
regression specification is identical to the form given by (2) above. To account for the
possibility that fund companies have become more careful after the scandal in the US,
we assume they engage in or knowingly allow late trading, if at all, only when it
appears to be most profitable. For this reason we include observations only when the
change in the price of future contracts between 12pm and 10pm is equal to or larger
than one percent.12
Insert Table 1 here
The coefficients in Table 1 provide evidence that inflow is correlated with market
swings pre-cutoff between 9am and 12pm and movements after market close between
5.30pm and 10pm. Post-market close price movements are most likely more important
for late traders than price movements during the afternoon because those changes are
naturally better predictors of next day’s returns. Replacing the last term of equation (2)
by hourly price changes shows the timing that late trading occurs. The coefficient
estimates of hourly price changes indicate that some trades are placed as late as
between 9pm and 10pm. To further examine how widespread late trading has been, we
repeat this analysis specifically for retail funds. These results are reported in columns 3
and 4 of Table 1. The coefficient estimates are almost identical to those reported in
columns 1 and 2. This finding is not surprising since most funds in our sample cater to
retail investors.13 Besides confining late trading to days on which post market close
price changes are large, it might be as profitable during periods with a high degree of
12 Consistent with the view that late trading is primarily used for profit maximization rather than loss avoidance or minimization, the alternative condition of market movements equal to or less than minus 1 percent may not work as well. Saying that we recognize that ‘stale price arbitrage’ may involve both buying at the stale price while expecting a gain on the next day and selling when the market is expected to decline. 13 We only find significant correlation between inflow and after market close price movements for retail funds but not for institutional funds. Hence the results for institutional funds are not reported in Table 1.

value-relevant information. To test this hypothesis, we reran our models including only
quarterly earnings announcement periods. We obtain similar results as in Table 1
regardless of different time window lengths around the end of a calendar quarter.14
In column 5 of Table 1 we report regression results using the entire sample without
the restriction to earnings announcement periods or that futures price changes have to
be over 1%. It is interesting that for those funds we also obtain similar results albeit a
bit weaker in statistical terms. In summary, we find evidence of late trading in French
mutual funds coupled with evidence that such practices may be even more pervasive
within retail funds. The latter suggests the culprits may be hiding their illicit trades
among the frequent subscription and redemption orders of retail investors. On the fund
family level, the net inflow of about 10% of the fund families is correlated to changes
in futures on the CAC40 between 5.30pm and 10pm. Our results are robust when we
control for the global financial crisis (GFC). In fact, excluding the GFC from the
sample period makes the results stronger since such a trading scheme is less likely to
be as widely used during a severe market downturn. Our results are also broadly
consistent with the report of the CESR investigation of French fund companies in
2004, stating:
“Despite the fact that the cutoff time is clearly defined in the prospectus of all
investment funds, its enforcement is variable depending on the different parties
involved in the processing of these subscriptions/redemptions.”
Indeed non-compliance with cutoff times is the core of late trading schemes and it
should have raised further concerns during the CESR investigation.
14 The results are slightly weaker in statistical terms but otherwise the same. These results are not included here, but are available from the authors.
11
Table 2 reports regression results for an equally-weighted portfolio of German
mutual funds. As before no particular cutoff time is legally set, but according to the
annotation of German statutory law, this should normally be 3pm. The 3 pm cutoff
corresponds the time stated in most prospectuses we have viewed.15
Insert Table 2 here
The results show that fund inflow is correlated with market movements between
3pm and 5.30pm and with futures price changes between 5.30pm and 10pm. The
coefficient on price changes between 9am and 3pm is -0.01 but not statistically
significant. Hence, information after the cutoff time and after market close for trading
in equities seems to be more important for capital flow into equity funds compared to
information emerging before and up to the valuation point. Surprisingly, all significant
coefficients are negative, i.e. net inflow is negative when price changes are expected to
increase. Recall, that we only include observations where the return between 3pm and
10pm is one percent or more. The price changes of future contracts are therefore
positive by default. We obtain similar results when we restrict the sample to futures
price changes in excess of minus one percent, just with opposite signs.
To investigate this anomaly further, we report in column 3 regression results that
include all observations but with a different specification. First, we use a dummy
variable with interaction terms added to show the different effects of moderate and
large price changes on net inflow. The dummy variable is equal to one when post-
cutoff market movements are one percent or more and zero otherwise. The negative
coefficients on the interaction terms confirm that the negative correlation is driven

specifically by trades during large market swings.16 Most of the large changes in future
prices occur during the height of GFC (September 2008 to March 2009) and during the
deepening of the SDC in late 2011. Consequently, we fit a second set of regressions
that include all observations but different dummy specifications capturing the GFC
and/or SDC effects over different time windows. Again we obtain similar results.17 For
example, the correlation between net inflow and changes in the market before the
cutoff time and after market close is positive (and statistically significant at the 10%
level) in a regression including a dummy variable coded to capture the height of the
GFC around the collapse of Lehman Brothers. The negative correlation is captured by
the dummy and interaction terms (e.g., t-statistic dummy = -5.43).18
We have by now enough evidence to establish that the negative correlations we
obtain are confined to periods of financial turmoil. This may be the result of late
trading involving short-selling funds or maintaining a market neutral position during
high uncertainty times rather than aiming at short-term returns. Such late trading
practices were, for example, prevalent during the sharp market downturns in 2001-
2002 as revealed by the findings of the investigation into the US scandal of 2003.19
Among others, it was revealed that late traders were provided with the exact portfolio
composition of their target funds allowing them to (1) short a copy of the portfolio in
the market and (2) buy shares in the fund for an equal dollar amount. With the hedge in
place, investors could then wait until an event drives the market enough causing both
sides of the hedge to be closed out. However, during a sharp market upswing it would
16 Fitting GARCH models with changes in the market after the cutoff time or market close as exogenous variables do not change the results. 17 These results are not presented in Table 2 but are available from the authors. 18 We obtain similar results if we simply exclude the GFC from the sample. For example, the t-statistics in a regression including all observations from March 2009 onwards are 1.23 (∆FUT 9am to 3pm), -0.46 (∆FUT 3pm to 5.30pm) and 1.96 (∆FUT 5.30pm to 10pm), respectively. And again the results are not significantly different when we re-estimate equation (3) including only quarterly earnings announcement periods. 19 See Complaint State of New York against Canary Capital Partners LLC, September 3, 2003.

be more reasonable to settle only the short leg of the paired trade, especially if an
investor can trade both stocks and funds late. Of course, keeping the long position
means speculating on a gain the following day. Yet this is not to say that by allowing
investors to trade late they will be willing to take the risk during times of extreme
market uncertainty as seen at the heights of the GFC and SDC crises.20
The analysis of Dutch mutual funds represents an interesting case as the CESR
investigation identified a long list of shortcomings in the area of transparency and
prudent working methods. The investigation included numerous on-site inspections
that involved review of accounts, procedures and correspondence between the fund
companies and affiliated or third parties. The findings however were allegedly not
related to late trading or other abusive trading practices. Table 3 reports regression
results for an equally-weighted portfolio of 34 Dutch mutual funds that invest in
domestic equities, representing about 50% of the Netherland’s fund industry in this
category.21 Cutoff time for most funds is 4pm. Futures on the AEX Index started
trading until 10pm in August 2009. The sample period is therefore from August 2009
through November 2013.
Insert Table 3 here
The first two columns show the results for the entire period. Information prior to cutoff
and from cutoff to market close is correlated to inflow with estimates of 0.09 and 0.06
and t-statistics = 6.25 and 2.2, respectively. The results of column 2 also show that
there is evidence of late trading after market close, between 7pm and 8pm. The
20 We have also assessed trading practices at the fund family level. We find a positive coefficient for changes in futures prices after market close for 18% of the fund families. In addition, we assessed trading practices using US technology and small cap funds, but did not find evidence supporting late trading. Similarly, we did not find any indications for such practices in the case of UK funds investing in domestic equities or US equities. These results are not presented in this paper, but are available from the authors. 21 Based on industry statistics provided by De Nederlandsche Bank for Q3 2013.

coefficient estimate is 0.12 with t-statistic = 1.97. Columns 3 and 4 report the results of
regressions using only observations around quarterly earnings announcements. We do
not condition on the magnitude of changes in future prices since this induces high
multicollinearity (large variance inflation factor).22 Besides, there are only 44 days in
which the return between 4pm and 10pm is one percent or larger. Table 3 only reports
results for a time window 10 days prior and 45 days after the end of the calendar
quarter, but the results are generally robust to different window lengths. We choose 10
days prior to the end of a quarter, since stock markets are forward looking and
expected earnings or preliminary sales and profit figures are often revealed or leak
ahead of the official press releases. The majority of companies report within 45 days
after the end of a calendar quarter (e.g. 75% of all Compustat firms). Apparently, much
value-relevant information is revealed during those periods thus, as noted earlier, late
trading should be more profitable. And indeed, the correlation between net inflow and
changes in futures prices after market close is more pronounced than that we estimate
over the entire sample period.
While the period after cutoff but before market close is correlated with inflow in
columns 1 and 2, this has somewhat shifted to later times post cutoff and also post
market close in columns 3 and 4. We now obtain significant coefficient estimates on
∆FUT7pm-8pm and ∆FUT9pm-10pm with values of 0.22 and 0.14 and t-statistics = 3.59 and
3.72, respectively. These estimates are much greater than the estimates shown in
columns 1 and 2. This shift is consistent with the timing of earnings after
announcements. Investors who are able to trade late will place their trades after the
announcements but at pre-announcement prices. In addition, we test late trading at the
at the individual fund level. We find evidence of late trading in 15% of the sample.
22 Our conclusions are not affected if we do condition on the magnitude of changes in future prices.

IV. Measuring Returns from Late Trading
In this section we quantify the potential return from late trading using French data
and compare it to a simple buy-and-hold strategy. For this purpose we assume an
investor was given late trading capacity recognizing that in practice, this would be
limited to the funds of specific investment companies or brokers that allow or facilitate
late trading. We estimate the return from late trading as the equally-weighted return on
the sample funds on day t if the change in future prices after the cutoff time on day t-1
is positive. If it is negative the investor stays out of the market and earns the risk free
rate; ergo
Table 4 illustrates that prior day changes in future prices might indeed be useful for
guiding the illicit trades. The correlation of changes in future prices after the cutoff
time with next day’s fund returns is between 0.310 and 0.416 (see Panel A). A
predictive regression shows it is the changes after market close that matter the most
(see Panel B).
Insert Table 4 here
Figure 1 shows that an investment of USD 100 would have almost ten-folded had
an investor been allowed to trade late at maximum frequency. Even during the GFC,
late trading mainly earned a positive return, whereas the buy-and-hold strategy has not
yet fully recovered from its losses during the GFC.23
Insert Figure 1 here
23 The buy-and-hold strategy has a cumulative return of 97% when the GFC is excluded from the sample period (March 2009 until October 2013), while late trading returns 542%.

16
Table 5 shows summary statistics for both return series. Average daily return from late
trading is 19 bps whereas it is -1 bps from the buy-and-hold strategy with t-statistics of
5.86 and -0.17, respectively. Based on 250 trading days, late trading earns an
uncompounded return of 47% per annum. At the same time, it has a much lower
standard deviation.24 This outperformance is mainly based on the strategy’s ability to
predict and sidestep negative fund returns. A late trader invests only half the time and
avoids about half of the negative returns a buy-and-hold investor would experience.
The table also shows statistics of returns from trading funds only when the change in
future prices is greater than 50 bps or 100 bps. This reduces the number of trades
substantially and produces annualized returns of 37% and 22%, respectively.
Considering that we ignore any possible refinements, the estimated returns in this
section are rather conservative. For example, by trading only high beta or small cap
funds, returns from late trading should be even higher.25 Note, we do not consider
transaction costs in our example as it is unlikely that late traders face front-or back-end
loads and the incurred costs of their trades are attributed to all investors of the funds.
The potential gains from late trading are similar in magnitude to the returns reported in
Goetzmann et al. (2001), Boudoukh et al. (2002) and Zitzewitz (2003). These papers
study the same underlying concept of exploiting stale prices that also applies to late
trading. The latter, however, is unambiguously unlawful and not a question of legal
limbo. Our analysis vividly shows why this practice was so widespread and probably
still is in some areas of the world.
Insert Table 5 here
24 The results are qualitatively the same when we base late trading on changes in future prices between 5.30pm and 10pm (after market close) and virtually unchanged assuming an investor earns zero return on cash instead of the risk free rate on days she has not invested in equity funds. 25 Our test based on the equally-weighted portfolio of funds comes close to an investor trading funds late randomly.
17
V. Further Work
So far, we have only examined funds investing in domestic equities, but we plan
next to extend our sample to international funds. Because of equities which trade in
different time zones, the asset prices used to calculate NAVs at the cutoff time might
not fully reflect movements in overseas markets that should make late trading more
profitable and potentially more widespread. We are currently collecting data for a
larger sample of European countries and selected emerging markets which may enjoy
less strict regulatory supervisory and scrutiny.
VI. Conclusion
We find statistical evidence for late trading in three countries, including two for
which no major shortcomings were identified during an investigation conducted by
European securities regulators in 2004. We would have expected that following the
events that rocked the US funds industry in 2003 and ensuing strengthening of
regulation should have made late trading more difficult to execute, but it appears to be
still present. Many reasonable proposals have been considered to thwart late trading.
Most of which recommend effective trading procedures and internal controls,
including different fee structures, strict forward pricing and fair value pricing.
However, recent occurrences of late trading highlight that there will probably always
be market participants who cannot resist the temptations of late trading, no matter the
system in place. The merits from placing safer bets, the prospects of large gains and
the relative simplicity of this practice are obvious. The profits from trading late,
however, are matched dollar-for-dollar by the losses of long term investors. Therefore,
we fully endorse the suggestion made by Zitzewitz (2006) that simple statistical
methods may be helpful and should be used on a regular basis in assessing and
monitoring the compliance of fund companies with law and best practices.
