Introduction Some emerging areas are controversial:
• Tactical asset allocation contradicts the EMH
• Stock lending and program trading have image problems
• Derivatives are not permitted in some portfolios

Tactical Asset Allocation What is tactical asset allocation? How TAA can benefit a portfolio Designing a TAA program Caveats regarding TAA performance
![Page 6: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/6.jpg)

What Is Tactical Asset Allocation?
Definition Intuitive versus quantitative techniques Overview of the technique Policy decisions Strategy
![Page 7: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/7.jpg)
7
Definition Tactical asset allocation (TAA) managers:
• Seek to improve the performance of their funds • By shifting the relative proportion of their
investments into and out of asset classes • As the relative prospects of those asset classes
change For example, shift to stocks if stocks are
expected to outperform bonds
![Page 8: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/8.jpg)
8
Definition (cont’d) TAA attempts to take advantage of short-
term deviations from long-term trends
The most difficult part of TAA is asset class appraisal• The process of determining the relative merits
of the various asset classes given current economic conditions
![Page 9: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/9.jpg)
9
Intuitive Versus Quantitative Techniques
In the intuitive approach, decisions are based on personal opinion and gut feeling• Suffers from hindsight bias
– Portfolio managers remember the times they were correct
![Page 10: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/10.jpg)
10
Intuitive Versus Quantitative Techniques (cont’d)
In the quantitative approach, managers use an analytical assessment and a system for implementing precise portfolio changes• E.g., use the gap between the S&P 500
dividend yield and the average yield on AAA corporate bonds
![Page 11: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/11.jpg)

Overview of the Technique
![Page 12: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/12.jpg)
12
Policy Decisions Policy decisions involve:
• Deciding to use a TAA program in the first place
• Establishing the extent to which the program will be employed
• Determining the number of asset classes to employ
![Page 13: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/13.jpg)
13
Strategy There are three alternative strategic
functions:• Static strategy maintains a static portfolio mix• Reactive strategy involves decisions based on
events that have already occurred• Anticipatory strategy involves shifting funds
before the markets move
![Page 14: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/14.jpg)
14
How TAA Can Benefit A Portfolio
The goal of an anticipatory strategy is to outperform the portfolio without TAA• The potential gains to a clairvoyant manager
from TAA are enormous (see next slide)
The portfolio manager must assess return within a risk/return framework
![Page 15: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/15.jpg)

How TAA Can Benefit A Portfolio (cont’d)
![Page 16: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/16.jpg)
16
Designing A TAA Program Before implementing a TAA program, a
fund manager must establish:• The normal mix
– The benchmark proportion each asset class constitutes in the portfolio
• The mix (exposure) range– Specifies how much the current mix can deviate
from the normal mix
![Page 17: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/17.jpg)
17
Designing A TAA Program (cont’d)
Before implementing a TAA program, a fund manager must establish (cont’d):• The swing component
– The percentage of the total portfolio whose composition by asset class may change
– The key element of TAA is properly investing the swing component
![Page 18: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/18.jpg)

Caveats Regarding TAA Performance
Efficient market implications Impact of transaction costs
![Page 19: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/19.jpg)
19
Efficient Market Implications TAA program implicitly assume it is
possible to outperform a buy-and-hold strategy by shifting asset classes• Inconsistent with the efficient market
hypothesis Some fund managers have good records
with TAA programs• Might be skill or luck
![Page 20: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/20.jpg)
20
Impact of Transaction Costs The portfolio incurs trading fees each time a
trade occurs
If the marginal gains from TAA switching do not exceed transaction costs, the program is not effective
![Page 21: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/21.jpg)

Stock Lending Definition Mechanics of a short sale How a stock lending transaction works Stock lending’s lucrative nature Regulatory concerns Long/short portfolios Certificateless trading
![Page 22: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/22.jpg)
22
Definition Stock lending:
• Is the practice by which one institution loans stock to another institution
• Is often used to support short-selling by customers of the second institution
• Can earn substantial income with very little risk
![Page 23: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/23.jpg)
23
Definition (cont’d) Stock lending is similar to a repurchase
agreement:• The institution wanting to borrow stock
– Puts up collateral (about 102 percent of the securities lent)
– Agrees to return the securities at a later date
• The lender can earn interest on the cash collateral
![Page 24: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/24.jpg)
24
Mechanics of A Short Sale A short sale:
• Involves borrowing securities from someone• Selling the securities to another market
participant• Eventually purchasing shares from another
market participant and• Returning the substitute shares to the original
lender
![Page 25: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/25.jpg)
25
Mechanics of A Short Sale (cont’d)
A short sale is normally motivated by a bearish sentiment
The actual lender in a short sale is normally an unknowing participant• A hypothecation agreement gives the broker
the right to lend shares to someone else– The investor can still trade the shares and continues
to earn dividends
![Page 26: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/26.jpg)
26
Mechanics of A Short Sale (cont’d)
The short seller:• Has an obligation to return what was borrowed
at some point in the future• Must pay dividends to the lender• Eventually covers short by repurchasing shares
to replace the shares borrowed earlier– If the purchase price is below the selling price, the
short seller makes a profit
![Page 27: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/27.jpg)

28
How A Stock Lending Transaction Works
If the customer wants to short sell:• The brokerage firm first checks if other
customers have the stock in a margin account• The brokerage firm may use a stock loan finder
to locate another firm with the needed shares• The first firm deposits collateral with the
second firm (T-bills or cash)– Part of the interest is used to pay a finder’s fee to
the stock loan finder
![Page 29: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/29.jpg)

Stock Lending’s Lucrative Nature
Advantages of stock lending Disadvantages of stock lending
![Page 30: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/30.jpg)
30
Advantages of Stock Lending Stock lending is very lucrative
• In 1999, the total income to stock lenders approached $1 billion
Stock lending is popular when markets see increased merger and acquisition activity:• Merger arbitrage involves buying shares of
likely takeover candidates and short selling shares of the anticipated acquirer
![Page 31: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/31.jpg)
31
Advantages of Stock Lending (cont’d)
Stock lending can be used by brokerage firms to finance the margin purchases of their customers
![Page 32: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/32.jpg)
32
Disadvantages of Stock Lending
A customer potentially gives up the right to vote:• The short seller is essentially a negative owner
Some risk is associated with the possibility that the stock borrower might not return the securities• Stock loans are “marked to market”
![Page 33: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/33.jpg)
33
Regulatory Concerns Stock lending does technically not fall under SEC
jurisdiction• Does not involve the purchase or sale of securities
A possible area of abuse lies in the lending of shares in cash accounts• Cash account holders do not sign hypothecation
agreements
![Page 34: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/34.jpg)
34
Long/Short Portfolios Short selling is an element of a hedging
strategy called building a long/short portfolio:• Combines elements of speculation, fundamental
stock analysis, and hedging to reduce risk– Sells overvalued shares and buys undervalued
shares
![Page 35: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/35.jpg)
35
Certificateless Trading The difference in settlement procedures across
countries can cause significant problems• E.g., U.S. settlement takes 3 business days versus 6
weeks in France
Computer automation makes it possible to process some types of transactions almost immediately• E.g., newly issued U.S. government bonds are
registered in book entry form only
![Page 36: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/36.jpg)
36
Program Trading Program trading:
• Is not easy to define
• Can be used to mean any computer-aided buying or selling activity in the stock market
![Page 37: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/37.jpg)
37
Program Trading (cont’d) The Wall Street Journal defines program
trading as the simultaneous purchase or sale of at least 15 different securities with a total value of $1 million or more
![Page 38: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/38.jpg)
38
Program Trading (cont’d) Stoll and Whaley elements of program
trading:• Portfolio trading
• Computerized trading
• Computer decision making
![Page 39: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/39.jpg)
39
Program Trading (cont’d) Program trading is also the generic term
used to describe any strategy that instantaneously recommends buy or sell order because of apparent arbitrage• E.g., buy futures and sell stock if the basis is
theoretically too small• E.g., buy stock and sell futures if the basis is
theoretically too wide
![Page 40: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/40.jpg)
40
Program Trading (cont’d) Program traders fall into one of two groups:
• Institutions that buy stock index futures and T-bills to create the equivalent of an index portfolio
• Institutions that combine a well-diversified stock portfolio with short position in stock index futures to create synthetic T-bills
![Page 41: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/41.jpg)
41
Program Trading (cont’d) Program trading has a bad name as it may
increase security price volatility
Many professional traders and investment managers believe that program trading benefits the public• Helps reduce commission costs
![Page 42: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/42.jpg)

Role of Derivative Assets Process of education Getting board approval
![Page 43: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/43.jpg)
43
Process of Education People think derivatives are speculative Various exchanges offer seminars on ways
in which derivative assets can be used in conservative portfolios• E.g., risk management conferences by CBOE,
CBOT, CME, LIFFE• Derivative asset education is designed to give
people more choices
![Page 44: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/44.jpg)
44
Getting Board Approval Once the portfolio manager is convinced of
futures and/or options, he must convince:• Boards of trustees• Supervisors or• Fund beneficiaries
The manager should be able to explain the merits of derivatives using everyday language
![Page 45: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/45.jpg)

The Chartered Financial Analyst Program
History The CFA program exams CFA program themes
![Page 46: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/46.jpg)
46
History The CFA program began in 1959 when the
Institute of Chartered Financial Analysts (ICFA) was formed
– Promotes investment education and ethical behavior– Awarded the first charter in 1963
The Financial Analysts Federation (FAF) merged with the ICFA in 1990 to form the Association for Investment Management and Research (AIMR)
![Page 47: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/47.jpg)
47
The CFA Program Exams To earn the CFA designation, candidates
must pass three separate exams taken at least a year apart• Each CFA exam is given only once per year
![Page 48: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/48.jpg)
48
The CFA Program Exams (cont’d)
Level I is multiple choice:• Covers basic tools and inputs to the investment
valuation process
Level II is essay, valuation, analysis, and problem sets• Emphasizes security valuation and specialized
topics
![Page 49: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/49.jpg)

CFA Program Themes Competence Presentation standards Fiduciary duties Ethics
![Page 52: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/52.jpg)
52
Competence People who complete the CFA program are
technically very competent and are likely to keep their noses clean during their professional careers
![Page 53: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/53.jpg)
53
Presentation Standards CFA candidates learn state-of-the-art
standards and may prepare their own reports in accordance with AIMR requirements
From a fiduciary perspective, compliance with AIMR requirements is on its way to being mandatory
![Page 54: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/54.jpg)
54
Fiduciary Duties Fiduciary duties require conduct that:
• Is in the individual client’s best interest• Is fair to the collective group of all clients
Research reports are an important part of fiduciary dutues
![Page 55: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/55.jpg)
55
Ethics The coverage of ethics in the CFA program
is very useful:• For example:
– Analysts must distinguish between fact and opinion
– Research reports should be objective, unbiased, and have a reasonable basis
– Bigger clients should not be given preferential treatment
![Page 56: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/56.jpg)

Regulation Fair Disclosure Introduction The SEC position The industry position AIMR response The future of the regulation
![Page 57: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/57.jpg)
57
Introduction Regulation FD was approved by the SEC
in August 2000 The key provision:
• Prevents companies from giving material information to security analysts, mutual funds, or institutional investors
• Unless the company simultaneously issues the same information to the general public
![Page 58: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/58.jpg)
58
The SEC Position The purpose of Regulation FD is:
• To increase the quantity and quality of available information to investors
• To eliminate what some perceive as an unfair advantage enjoyed by Wall Street’s big guns
![Page 59: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/59.jpg)
59
The Industry Position Evidence indicates that less information is
available to the public:• Companies are reluctant to answer questions
not publicly answered before• Companies have begun to provide less
information between quarterly reports• Quarterly conference calls between firms and
the brokerage industry have become scripted
![Page 60: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/60.jpg)
60
AIMR Response AIMR study when Regulation FD was first
announced:• “To avoid any possible SEC enforcement
actions, corporations will reduce their communications to ‘sound bites’ and ‘boilerplate’ disclosures”
![Page 61: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/61.jpg)
61
AIMR Response AIMR study one year later:
• “While the overall goal of providing small investors and investment professionals with the same information is being achieved, it has been at the cost of less information in terms of quantity and quality”
![Page 62: Chapter 25 Contemporary Issues in Portfolio Management](https://reader033.vdocuments.net/reader033/viewer/2022061409/56814f7e550346895dbd304e/html5/thumbnails/62.jpg)
62

business have long needed improvement
The Enron collapse brought the issue of security analyst independence in the spotlight

Analyst Ratings A high proportion of analyst stock ratings
are positive• Firms have little incentive to begin coverage of
a firm that is unlikely to be an attractive investment
– “Buy” recommendations bring in more business than “sell” recommendations

Analyst Ratings (cont’d) NASD proposals in early 2002 require
analysts to:• Better explain their rating system
• Disclose banking relationship with companies they cover
• Not earn a bonus from attracting underwriting business from the firms they cover

Bullish Ratings as the Ship Sinks
Sudden adverse news that hits a company is difference from a gradual accumulation of negative events coupled with an analyst’s hope that things will improve• E.g., dot.coms in 1999 and 2000
– Some analysts maintained “buy” recommendations four days before the firm went into bankruptcy

Separation of Research and Investment Banking
The opinion of a security analyst should not be biased by activities elsewhere in the firm
The Security Industries Association list of best practices states:• “Research should not report to investment
banking; it should also not report to any other business unit in a way that compromises its integrity”
