Investment management
(also called fund management,
asset management or
portfolio management) is the
process of investing a portfolio on an ongoing basis. While the term and
its synonyms can be applied broadly, they are usually reserved for
instances where the investing is performed by one or more professionals.
The professionals are called investment
managers (fund managers,
asset mangers or
portfolio managers). There are
typically three ways investors can employ investment managers:
They
can hire investment managers as employees or contractors.
They
can become a client of a firm called an
investment management firm
that will manage the portfolio for a fee.
They
can purchase shares of a mutual fund, join a limited partnership or
otherwise invest in some pooled investment vehicle.
An investment management firm may be called a
fund management firm or
asset management firm. It may
simply be called an investment manager or any of the synonyms of
investment manager. So, for example, "fund manager" might refer to a
person or a firm. Some well known investment management firms are
Barclays Global Investors in the UK, and Fidelity Investments, State
Street Global Advisors or The Vanguard Group in the US. Investment
management firms and pooled investment vehicles are collectively
referred to as the
investment management industry.
Investors fall broadly into two categories. There are
individual investors (also called
retail investors) who are
individuals or perhaps families investing their own funds. They may
manage their own investments without investment managers, directly
investing through a brokerage account, bank savings account, government
savings bonds or
certificates of deposit. If they do utilize investment managers, it
is usually through the third of the above three options: investing in
pooled investment vehicles such as mutual funds.
The second category of investors is
institutional investors. These
include pension funds, insurance companies, endowments or foundations.
These may use any of the above three options for employing investment
managers or some combination of the three. Institutional investors also
include pooled investment vehicles, such as mutual funds or limited
partnerships, mentioned in the third of the above three options. How do
these invest the assets they pool? Some rely on investment managers who
are officers, senior partners or employees of the pooled investment
vehicle. Venture capital funds,
hedge funds and private equity funds typically follow this model.
Other pooled investment vehicles turn to an investment management firm
to manage their assets. This is typically how mutual funds operate. A
few pooled investment vehicles invest their assets in other pooled
investment vehicles. For example, some hedge funds are structured as
funds of funds, investing in
other hedge funds.
Ultimately, a significant component of retail
investments and essentially all institutional investments are entrusted
to investment managers of one sort or another. Because different
portfolios have different investment objectives, investment managers
need guidance as to how a portfolio is to be invested. A defined benefit
pension plan will generally want to be invested for the long term,
perhaps in equities or
bonds. An auto insurer, on the
other hand, will have a shorter horizon and be largely invested in money
market instruments. Investment objectives are communicated as investment
policies.
Investment policies are typically specified by the
investor in situations where a portfolio manager is an employee of the
investor or an investment management firm hired by the investor. Pooled
investment vehicles generally set their own investment policies, so it
is up to would-be investors to invest in pooled investment vehicles
whose investment policies conform to their needs.
Investment policies can be specific about how a
portfolio is to be invested or grant the portfolio manager broad
discretion. They indicate what asset classes are acceptable and impose
constraints, perhaps related to the investor's
risk aversion, regulatory
restrictions or tax status.
Investing a portfolio entails both strategic and
tactical decisions. Asset allocation is a strategic decision about what
fraction of assets should be invested in a given asset classes, such as
domestic equities, foreign equities,
corporate bonds, etc. This
decision can be made by the investor, in which case the investor might
hire separate investment managers to manage each asset class. Or the
decision can be left to a single investment manager who then manages the
entire portfolio.
On a tactical level, individual investments must be
made—what in equity markets is called stock
picking. Market
timing is a tactic of getting in or out of a particular market—or
even going short that market—to
take advantage of anticipated rises or declines in that market. In fixed
income markets, an investment manager might tactically decide to
lengthen or shorten the
duration of a portfolio or to increase or decrease its
credit risk.
There are two fundamentally different approaches to the
tactical aspects of investment management. With active investing the
portfolio manager actively picks investments or otherwise adjusts the
portfolio in ways that he anticipates will enhance its
returns. With passive investing,
the manager passively manages a portfolio of investments with holdings
that match those of some benchmark index, or he otherwise manages a
portfolio to have returns that closely match those of the benchmark
index.
There is a vast scholarly literature on topics related
to investment management. One field of research is
portfolio theory, which
explores how asset allocation and investment selection should be
performed so that portfolios are in some sense optimal.
Efficient markets
theory explores the relative merits of active vs. passive investing.
Results have generally supported the conclusion that active managers as
a group fail to outperform passively managed portfolios. Because active
managers charge higher fees and generally incur higher
transaction costs, this
has prompted many investors to opt for passively managed portfolios.
Active managers' performance is assessed by investors
using techniques of performance assessment. The factors that contributed
to a manager's performance can then be determined using techniques of
performance attribution.
