Investment aims and Benchmarking
Each fund has a defined investment goal to describe the remit of the investment manager and to help investors decide if the fund is right for them. The investment aims will typically fall into the broad categories of Income (value) investment or Growth investment. Income or value based investment tends to select stocks with strong income streams, often more established businesses. Growth investment selects stocks that tend to reinvest their income to generate growth. Each strategy has its critics and proponents; some prefer a blend approach using aspects of each.
Funds are often distinguished by asset-based categories such as equity, bonds, property, etc.
Also, perhaps most commonly funds are divided by their geographic markets or themes.
Examples
* The largest markets - U.S., Japan, Europe, UK and Far East are often divided into smaller funds e.g. US large caps, Japanese smaller companies, European Growth, UK mid caps etc.
* Themed funds - Technology, Healthcare, Socially responsible funds
In most instances whatever the investment aim the fund manager will select an appropriate index or combination of indices to measure its performance against; e.g. FTSE 100. This becomes the benchmark to measure success or failure against.
Active or passive management
The aim of most funds is to make money by investing in assets to obtain a real return (i.e. better than inflation).
The methods used to make your investment vary and two opposing views exist.
Active management - Active managers believe that by selectively buying within a Financial market that it is possible to outperform the market as a whole. Therefore they employ dynamic portfolio strategies buying and selling investments with changing market conditions.
Passive management - Passive managers believe that it is impossible to predict which individual holdings or section of the market will perform better than another therefore their portfolio strategy is determined at outset of the fund and not varied thereafter. Many passive funds are index trackers where the fund tries to mirror the market as a whole. Another example of passive management is the "buy and hold" method used by many traditional Unit Investment Trusts where the portfolio is fixed from outset.
An example of active management success
* In 1998 Richard Branson (head of Virgin) publicly bet Nicola Horlick (head of SG Asset Management) that her SG UK Growth fund would not beat the FTSE 100 index, nor his Virgin Index Tracker fund over three years, nor achieve its stated aim to beat the index by 2% each year. He lost and paid £6,000 to charity.
Alpha, Beta, R-squared and standard deviation
When analysing investment performance, statistical measures are often used to compare 'funds'. These statistical measures are often reduced to a single figure representing an aspect of past performance:
* Alpha represents the fund's return when the benchmark's return is 0. This shows the fund's performance relative to the benchmark and can demonstrate the value added by the fund manager. The higher the 'alpha' the better the manager. Alpha investment strategies tend to favour stock selection methods to achieve growth.
* Beta represents an estimate of how much the fund will move if its benchmark moves by 1 unit. This shows the fund's sensitivity to changes in the market. Beta investment strategies tend to favour asset allocation models to achieve outperformance.
* R-squared is a measure of the association between a fund and its benchmark. Values are between 0 and 1. Perfect correlation is indicated by 1, and 0 indicates no correlation. This measure is useful in determining if the fund manager is adding value in their investment choices or acting as a closet tracker mirroring the market and making little difference. For example, an index fund will have an R-squared with its benchmark index very close to 1, indicating close to perfect correlation (the index fund's fees and tracking error prevent the correlation from ever equalling 1).
* Standard deviation is a measure of volatility of the fund's performance over a period of time. The higher the figure the greater the variability of the fund's performance. High historical volatility may indicate high future volatility, and therefore increased investment risk in a fund.
Types of risk
Depending on the nature of the investment, the type of 'investment' risk will vary.
A common concern with any investment is that you may lose the money you invest - your capital. This risk is therefore often referred to as capital risk.
If the assets you invest in are held in another currency there is a risk that currency movements alone may affect the value. This is referred to as currency risk.
Many forms of investment may not be readily salable on the open market (e.g. commercial property) or the market has a small capacity and investments may take time to sell. Assets that are easily sold are termed liquid therefore this type of risk is termed liquidity risk.
Note that the investor is indifferent to the type of risk, and should not care whether a loss comes from capital risk, currency risk, or liquidity risk - a loss is a loss.
