Motivation
“Our system of investor protection is predicated on the notion thatinvestors who are armed with complete and accurate information willbe able to look out for their own interests. This concept may be overlyoptimistic in its assumptions about the financial sophistication ofaverage retail investors.” (Barbara Roper, Consumer Federation ofAmerica)
Dumitrescu & Gil-Bazo Persistence in Mutual Fund Performance 2 / 34
Motivation
Investor protection focused on information disclosure
Too optimistic about retail investors’ financial sophistication:
Biases (e.g., Barber and Odean, 2000; Bailey, Kumar, and Ng,2011)Financial illiteracy (e.g., Lusardi and Tufano, 2009; van Rooij et al.2011)Frictions: search costs, switching costs, information processingcosts (Hortaçsu and Syverson, 2004; Brunnermeier and Oehmke,2009)Some investors more sophisticated than others

Berk and Green (2004)
Berk and Green (BG) (2004): If investors compete for the best mutual fundsin a friction-less market with increasing marginal trading costs, all fundsshould deliver zero net expected risk-adjusted return in equilibrium
Empirical evidence favorable to diseconomies of scale hypothesis (Chen etal., 2004; Yan et al., 2008; Turtle and Wang, 2013)
...but not to BG’s model implications:
Average fund earns negative net alpha (e.g., Jensen, 1968; Gruber,1996; Wermers, 2000)
Underperformers persist (Carhart, 1997) and some evidence ofshort-term persistence in outperformance (Bollen and Busse, 2004)
Performance predictable from fees and trading costs (e.g., Gil-Bazo andRuiz-Verdu, 2009; Edelen, Evans & Kadlec, 2007)

What we do
We develop a BG-type model (an active manager competes against apassive investment) with investors characterized by frictions: search costsand financial constraints
Findings:
Negative expected (net) performance in equilibrium
Expected performance increasing in expected managerial skill⇒ Persistence
New prediction: Persistence more prevalent among more visible funds (higherfraction of unsophisticated investors)
We then test the model’s new prediction with the data

The model
Model retains BG’s main features: rationality and diseconomies of scale
Frictions:
Search costs: Each investor i has a specific search cost γi that reflectsher ability to find an alternative investment: an index fund with zeroperformance
i-th investor’s reservation return = −γi
Financial constraints: Investor i endowed with m dollars and subject toa liquidity shock with probability γi , expected investment = m (1− γi ) .
We also consider an entry cost, K , borne by new investors

When the manager chooses f to maximize fq∗t+1(f ):
f increases with φ,
however, f increases less that one-to-one with φ, so TP stillincreasing in phi ,
except when there is no entry of investors

Testing the Model
Difficult to base our test on investor sophistication
Instead, test the prediction that performance of high-visibility fundsmore sensitive to managerial skill
Since managerial skill persistent (by definition?), performance ofhigh-visibility funds should persist longer
Unexpected result!
Test: regress future performance on past performance, comparecoefficient between high- and low-visibility funds

Empirical Strategy
We construct a panel of monthly risk-adjusted portfolio alphas using Carhart’s(1997) model:
rit = αi + βrm,i rmt + βsmb,ismbt + βhml,ihmlt + βpr1y,ipr1yt + εit
Compute past and future 12-month alphas and estimate by pooled OLS:
α̂i,t :t+11 = θ0,t + θ1α̂i,t−12:t−1 + θ2α̂i,t−12:t−1LOi,t−1 + θ3α̂i,t−12:t−1HIi,t−1 +
+θ4LOi,t−1 + θ5HIi,t−1 + ΘX ′i,t−1 + εi,t :t+11,
LO, HI, dummy variables for low- and high-visibility funds, respectively
We are interested in θ2 and θ3
Dumitrescu & Gil-Bazo Persistence in Mutual Fund Performance 21 / 34
Empirical strategy
Proxies for fund visibility:1 Number of different investment categories in which the family
offers mutual funds;2 Family size, as proxied by the natural logarithm of total family
assets;3 Family age, computed as the age of the oldest fund in the family;4 Average advertising expenditure over the previous 12 months
For each one of these proxies: define LO (bottom 25%) and HI (top25%) dummies

Data
CRSP MFDB, July ’11 version, 1993-2010
Advertising data from Kantar Media, 1995-2009
We aggregate class-level monthly observations at the portfolio level
Data: TNA; return; investment category; exp. ratio; 12b-1 fee; front-endload; back-end load
We exclude index, non-domestic, non-diversified, non-equity funds
Portfolios and fund families identified by CRSP or name
We exclude funds with TNA<$15M and age<3yr
Average: 1,251 funds and 327 families (m.co.)
Fee and return data winsorized at 1% of each tail each month
