Standard Deviation of a Fund - A statistical measure


It the core of the fund analysis activity lies the twin pursuits of judging returns and risk. Stripped of a lot of the complexity, this task involves determining a fund's average performance over a period of time. Let's get down to basics and take a refresher course on this concept.

Why do we use an average? Why don't we use the actual numbers that the average is calculated from? Obviously, because an average gives us a single value that represents the numbers it is calculated from. It is far easier to use a single number for judgement and comparisons.


But like most things in life, averages can be both good and bad. They can be trustworthy, or they can be worthless, or they can be anywhere between the two. For example, the average age of children in a kindergarten is three years. You could walk into a kindergarten expecting most kids to be more-or-less three years old and you would not be wrong. However, the average age of students in a school is 12 years. You could walk into a school expecting most students to be more-or-less 12 years old and you would be almost completely wrong. Around 90 per cent of the students would NOT be 12 years old -- they would be all ages from 5 to 18 years.


What happened? Was the average wrong? Obviously not, but it was not a very useful figure. It would have been far more useful if you had been told that most of the individual ages in the kindergarten were close to the average but most of the individual ages in the school were far from the average.


This is exactly what Standard Deviation does. It gives you a 'quality rating' of an average. The Standard Deviation of an average is the amount by which the numbers that go into an average deviate from that average. It tells us how closely an average represents the underlying numbers.


Let's put it this way: There was very little risk in assuming that the kindergarten's average represented the real ages but there was a great deal of risk in assuming that the school's average represented the real ages.


Risk! Isn't that what we are trying to figure out? So a recipe for figuring out the risk level of a fund takes shape:

1. Calculate a fund's monthly performance over a long period of time.

2. Calculate the average for all these monthly performances.
3. If the individual monthly performances are very different from the average, then that fund is risky, delivering high returns in some months and poor returns in others. If they are mostly similar, then the fund is a low risk one, with about the same returns month after month.


And how do we find out if mutual funds are 'very different' or 'mostly similar'? By calculating their average, of course. We just calculate exactly how much each month's performance is different from the average and then calculate the average of these differences. This is Standard Deviation. (While the actual formula is complex, this suffices as a simplified explanation.)


But you do need to be careful of one thing -- a high Standard Deviation may be a measure of volatility, but it does not necessarily mean that such a fund is worse than one with a low Standard Deviation. If the first fund is a much higher performer than the second one, the deviation will not matter much.

Mutual Fund Reivew: Birla Sun Life Asset Allocation Conservative

Birla Sun Life Asset Allocation Conservative has numbers on its side to prove its credibility… Don't be surprised to find this Fund of Funds ( FoF ) in our recommendations. It has earned its place. And despite the difference in the structure of the product, there is no arguing with the numbers.   Of the total 6 years of its existence, the fund has been among the top 10 funds in its category in four of them. Last year it put up an average show and the only year it underperformed its peers was in 2008.   One aspect to look at when investing in an FoF is the expense ratio. The expense ratio of an FoF is capped at a lower limit of 0.75 per cent (2.50% for an actively managed fund). However, the FoF not only has its own expense (though lower) but even the expense ratio of the fund it is investing into. Fortunately, the fund manager takes that into account. "Expense is one of the important criteria used for fund selection and is the main reason for our investment in BSL Ind...

Short-Term Investment Options in Mutual Funds

Mutual funds offer liquid funds and ultra short term funds in the debt category, which are suitable for short investment periods. Ultra short-term funds were earlier known as liquid plus funds. Liquid funds invest in money market instruments with a maturity of 91 days or less. However, there are no such restrictions for ultra short-term funds. Who should invest in these? These are open-ended schemes. Investors with a short investment horizon or with surplus cash and low risk appetite should look at these. These could include corporate as well as retail investors. Those interested in staying invested for less than 15 days can opt for liquid funds. Retail investors who want to remain invested for two-four months, can look at ultra short-term funds. The short duration for both liquid and ultra short-term funds shields them from any interest rate volatility.   What kind of returns do they offer? In terms of an investment period less than 15 days, these funds are comparable to a ba...
