Our first investor, the dogmatist, has extreme prior beliefs about the potential for
manager skill. The dogmatist rules out any potential for skill, either fixed or time varying,
for any fund manager. That is, the dogmatist’s view is that ai0 is fixed at 1
12ðexpense þ
0:01 turnoverÞ and that ai1 is fixed at zero, where expense and turnover are the fund’s
reported annual expense ratio and turnover, and where we assume a round-trip total trade
cost of 1% (this prior specification is similar to Pastor and Stambaugh (2002a,b)). The
dogmatist believes that a fund manager provides no performance through benchmark
timing or stock selection skills, and...

We consider two types of dogmatists. The first is a ‘‘no-predictability dogmatist (ND),’’
who rules out predictability, additionally setting the parameters bi1 and Af in Eqs. (1) and
(2) equal to zero. The second is a ‘‘predictability dogmatist (PD),’’ who believes that
mutual fund returns are predictable based on observable business cycle variables. We
further partition our PD investor into two types: PD-1, who believes that fund risk
loadings are predictable (i.e., bi1 is potentially nonzero), and PD-2, who believes that both
risk loadings and benchmark returns are predictable (i.e., bi1 and Af are both allowed to be
nonzero). Note that our PD investors believe that asset...

Our sample contains a total of 1301 open-end, no-load U.S. domestic equity mutual
funds, which include actively managed funds, index funds, sector funds, and ETFs
(exchange traded funds). Monthly net returns, as well as annual turnover and expense
ratios for the funds, are obtained from the Center for Research in Security Prices (CRSP)
mutual fund database over the sample period January 1975–December 2002. Additional
data on fund investment objectives are obtained from the Thomson/CDA Spectrum files.
In Appendix A, we provide both the process for determining whether a fund is a domestic
equity fund as well as a description of the characteristics of our investable equity funds....

Instruments used to predict future mutual fund returns include the aggregate dividend
yield, the default spread, the term spread, and the yield on the three-month T-bill, variables
identified by Keim and Stambaugh (1986) and Fama and French (1989) as important in
predicting U.S. equity returns. The dividend yield is the total cash dividends on the value-
weighted CRSP index over the previous 12 months divided by the current level of the
index. The default spread is the yield differential between Moodys BAA-rated and AAA-
rated bonds. The term spread is the yield differential between Treasury bonds with more
than ten years to maturity and T-bills that mature...

Next, we examine predictability in both benchmark returns and fund risk loadings.
Consider the dogmatist who believes in such a predictability structure (PD-2). This
investor would experience a nontrivial utility loss of 15.1 basis points per month (1.8%/
year) in December 2002 if forced to hold the optimal portfolio of the ND. The utility loss is
even larger over the course of all 276 monthly investments. This loss averages 21.1 (39)
basis points per month over expansions (recessions).
Moreover, the optimal portfolio of the PD-2 investor consists of very different
mutual funds, relative to those optimally selected by investors who disallow predictability
or who allow predictability only in...

Indeed, in the presence of predictability in fund risk loadings and benchmark
returns, optimal portfolios consist entirely of actively managed funds even when the
possibility of manager skills in stock selection and benchmark timing is ruled out. That is,
actively managed funds allow the investor to capitalize on predictability in benchmarks
and fund risk loadings in a way that cannot be achieved through long-only index fund
positions.
We now turn to analyze predictability in manager skills. Incorporating such
predictability results in asset allocation that is overwhelmingly different from the other
cases examined. To illustrate, consider the agnostic who believes in predictable skills (PA-
3). This investor faces an enormous...

Here, we analyze the ex post, out-of-sample performance of various portfolios strategies
through a sequence of investments with monthly rebalancing. Optimal portfolios are
derived first using the initial 60 monthly observations, then using the first 61 monthly
observations, and so on, ... ; and are finally rebalanced using the first T 1 monthly
observations, with T ¼ 336 denoting the sample size. Hence, the first investment is made at
the end of December 1979, the second at the end of January 1980, and so on, ... ; with the
last at the end of November 2002. We obtain the month-t realized excess return on each
investment...

This is a good time for a review of the academic literature on evaluating
portfolio performance, concentrating on professionally managed invest-
ment portfolios. While the literature goes back to before the 1960s,
recent years have witnessed an explosion of new methods for perfor-
mance evaluation and new evidence on the subject. We think that
several forces have contributed to this renaissance. The demand for
research on managed portfolio performance increased as mutual funds
and related investment vehicles became more important to investors
in the 1980s and 1990s. During this period, equity investment became
widely popular, as 401(k) and other defined-contribution investment
plans began to dominate defined-benefit plans in the United...

While the demand for research on investment performance has
increased, the cost of producing this research has declined. Early
studies relied on proprietary or expensive commercial databases for
their fund performance figures, or researchers collected data by hand
from published paper volumes. In 1997, the Center for Research in
Security Prices introduced the CRSP mutual fund database, com-
piled originally by Mark Carhart, into the academic research market.
Starting in about 1994, several databases on hedge fund returns and
characteristics became available to academic researchers. Of course,
during the same period the costs of computing have declined dra-
matically. In response to an increased demand and lower costs of
production, the...

Given that it is hard to believe mutual fund investors experience little over half the returns
delivered by their funds, let us illustrate the above phenomenon with a hypothetical example: In
Year 1, mutual fund Red Hot is small, has 10,000 shareholders, and returns 35%. As a result
of its good performance, Red Hot attracts new money and, in Year 2, has 50,000 shareholders.
As a consequence of its larger size, however, the fund delivers only 5% in Year 2....

The study covered mutual fund expense ratios (not including market impact costs) and the
behavior of these ratios with respect to mutual fund complexes and individual product lines with
various amounts of assets under management.
In particular, the study covered all 533 mutual fund complexes that existed in the United States
during the years 1990 to 1994, encompassing assets totaling about $2 trillion at the end of the
period. A mutual fund complex is a sponsor which may offer anywhere from...

With respect to equity mutual funds, the study further notes that funds are experiencing
diseconomies of scale in their expense ratios when their size exceeds $600 million to
$800 million.
Interestingly, the foregoing study does not even address the problem of market impact costs
which are clearly an even greater expense to mutual funds than are the more visible costs used in
the calculation of their...

Although the Standard & Poor's 500 is the most commonly used measure of the performance of
the U. S. stock market, it is sometimes argued that, because this index is so heavily populated
with high quality, large capitalization stocks, it may not be an appropriate benchmark with which
to compare a mutual fund which may be invested in lower quality, smaller capitalization stocks.
The obvious refutation: If one can obtain a higher return by investing in...

The fact that the shortfall figures have been rising over the past twenty years indicates that the
mutual fund industry's market impact problems are becoming increasingly severe. This is not
surprising, given the rapid growth in the size of mutual funds and an increase in the rates of their
portfolio turnover.
In any event, it appears that the combination of reported expenses and market impact costs, on
average, now consumes the mutual fund investor's capital at a...

Ondjiva, an Angolan town on the border with Namibia, often
goes for years without significant rainfall. When it does rain,
floods sweep across the flat ground leaving little stored for
future use. Those who can afford to do so buy their water
from tankers, spending on average one third of their monthly
income. Others buy from men like Antonio - his barrel weighs
nearly ¼ tonne, and it will have taken him much of the day to
roll it into town, earning him around 20 pence.
Many people can afford neither; meaning girls and women
must spend time...

We are aiming to create new partnerships with the private sector to increase green investments. The aim
is to demonstrate to major private sector investors that climate friendly investments are financially viable.
In particular we are working on two partnerships with the private sector for climate-friendly funds.
We and other public sector players will consider investing in these funds alongside private pension and
sovereign wealth funds. The funds will invest directly in renewable energy projects, and also in sub-funds
to support investments in, for example: energy efficiency, renewable energy, clean tech inventions, forestry,
public transport, urban development and waste treatment....

Recognising that significant levels of investment are required to make the transition to a low carbon
economy, the Capital Markets Climate Initiative (CMCI) was launched by the UK Minister of State for
Climate Change, Gregory Barker, to help accelerate the response to this financing challenge by supporting
the scale up of private finance flows to developing countries. The CMCI will be working with policymakers in
developing countries to understand why and how public sector action can help mobilise private capital and
encourage new markets in low carbon investments. This will focus on the role of “investment grade” policy,
including public...

Many countries around the world are partly prefunding their otherwise pay-as-you-go (PAYG)
financed social security systems by establishing or further developing existing public pension reserve funds
(PPRFs). Most OECD countries have put in place internal and external governance mechanisms and
investment controls to ensure the sound management of these funds and better isolate them from undue
political influence. These structures and mechanisms are in line with OECD standards of good pension
fund governance and investment management. In particular, the requirements of accountability, suitability
and transparency are broadly met by these reserve funds. However,...

Professional investors often explicitly or implicitly claim to understand the
fundamentals of finance theory. They may, for example, base allocation decisions on
historical returns, volatility, correlations of returns across funds or asset classes,
investment fees, industry outlooks, or various other financial metrics. Most 401(k)
participants do not have access to much of that information or are poorly equipped
to benefit from it. They may be guided by recent historical returns, which are
typically readily available and understood, even if incorrectly so. Funds with higher
returns understandably appear more attractive to investors. However, the finance
literature...

To date, most mutual fund performance evaluations have been fairly simplistic: how has a fund
performed relative to “the market”? The Standard & Poor’s 500 Stock Index is usually used as a proxy for
the market, despite the fact that it accounts for only about 70% of the capitalization of the U.S. stock market
and is dominated by corporations with gigantic market capitalizations. (Its largest 25 stocks account, on
average, for 1% of the entire market; the 6500 “non-500” stocks in the market have an average weight of
4/1000 of 1%.) But today, many funds resemble...

Many governments acknowledge that environmental degradation and climate change pose
international and trans-boundary risks to human populations, economies, and ecosystems that
could result in a worsening of poverty, social tensions, and political stability. To confront these
global challenges, countries have negotiated various international agreements to protect the
environment, reduce pollution, conserve natural resources, and promote sustainable growth.
While some observers call upon developed countries to take the lead in addressing these issues,
efforts are unlikely to be sufficient without similar measures being implemented in developing
countries. Developing countries, however, focused on poverty reduction and economic growth, do
not have the...

The United States and other industrialized countries have committed to financial assistance for
environmental initiatives through several multilateral agreements (e.g., the Montreal Protocol
(1987), the United Nations Framework Convention on Climate Change (1992), United Nations
Convention to Combat Desertification (1994), and the Copenhagen Accord (2009)). International
financial assistance takes many forms, from fiscal transfers to market transactions, and includes
foreign direct investment (FDI), bilateral overseas development assistance (ODA), and
contributions to multilateral development banks (MDB)
and other international financial
institutions (IFI), as well as the offering of export credits, loan guarantees, insurance products,
etc. ...

With their high share of trading turnover, hedge funds play a critical role in
providing liquidity for mis-priced assets, particularly when large volumes
are traded in thin markets – thereby reducing volatility. This activity is
particularly important, given the rapid growth in volume of new-generation
structured products issued by investment banks.
Hedge fund leverage estimated via an induction technique suggests a
leverage ratio that must be above 3 (versus total AUM of USD 1.4 trillion).
Gearing is required to boost returns where low risk and low return styles
are implemented. Investment banks are well capitalised against hedge...

“Structured products” are one of the fastest growing areas in the financial
services industry, and may already be over half of the notional size of the
hedge fund industry (AUM plus leverage). These products, constructed by
investment banks, are extremely complex using synthetic option replication
techniques, and offering a variety of guarantees in returns. They are sold to
retail, private banking and institutional clients. Hedge funds help reduce
volatility risk for investment banks in supplying these products. ...
8/30/2018 1:40:21 AM +00:00
Investment banks have strong capital adequacy, in particular with
respect to their hedge credit fund exposures – some estimates of
which are provided below.
Ironically, the fastest growing area of new financial products that
utilise highly-complex derivative products exclusively lies mostly
within the regulated sector. This is the market for “structured
products” that are produced by investment banks and sold to retail,
private bank and institutional clients. The strong volume growth in
this area, particularly in Europe and Australasia, creates ex-ante
derivative pricing pressure, and hedge funds frequently take the
other side of the trades (reducing ex-post volatility). ...
8/30/2018 1:40:21 AM +00:00
The size of this market is very roughly estimated to be around
USD 3.8 trillion, already over half of the notional size of the hedge
fund industry (AUM plus leverage), and growing quickly in the
last two years.
Structured products are passive in nature (unlike hedge fund active
styles), and focus on providing returns (for different risk profiles
of clients) with some element of capital guarantee. Constant
proportion portfolio insurance (CPPI) is one of the popular new-
generation techniques. These products have not been tested when
major anomalies in volatility arise. They are highly exposed to
downward price gaps in...

Hedge Funds have grown quickly over the past ten years,
and are important part of the financial landscape. They are
difficult to define as entities, because the line between what
hedge funds do that other institutions do not is blurred –
proprietary traders in investment banks, private equity funds,
and fund managers all use extensive leverage and derivatives
to trade markets or to shift risks.
The definition of a hedge fund used here is as follows:
lightly-regulated managers of private capital that use an active
investment approach to play arbitrage opportunities that arise
when mis-pricing of financial instruments...
8/30/2018 1:40:21 AM +00:00
The main differences between a hedge fund and a private
equity fund are: (a) the private equity fund looks to use
leverage to buy companies to obtain full management control
for purposes of changing its structure operations, whereas a
hedge fund trades assets without looking for full control; (b)
the hedge fund covers a multitude of styles, only one small part
of which might involve buying shares to force management to
make value enhancing changes (activist); and (c) hedge funds
often (but not always) have a shorter investment horizon than
private equity firms.
Overall, hedge funds...
8/30/2018 1:40:21 AM +00:00
The analysis in this paper suggests that hedge funds play a
very positive role in financial markets by providing liquidity to
thin markets where mis-priced financial instruments are to be
found. This type of activity reduces volatility rather than
increasing it.
Indeed with the rapid growth of structured products in
recent years, particularly in Europe and Asia, hedge funds
have been quite critical in containing the volatility that might
otherwise have arisen. Structured products are largely driven
by investment banks, and have resulted in the proliferation of
new and highly-complex derivative products (discussed
below).
Figure 1 shows...

A summary of the different styles of hedge funds and
the proportion of the market they occupy is shown in Table
4, based on Hedge Fund Industry Research data. An
indication of the broad activity involved in the style is
shown on the right hand side. Most of these strategies are
long-short in nature: all of the equity hedge (e.g. long a
stock and long a put to hedge its fall); most of event driven
(e.g. buy the target M&A company and sell the buyer); all of
relative value arbitrage (e.g. buy the London listing and sell
the...
