How do you choose an index fund?
A few months ago, we had written about index funds being a good
option for first time investors in equity. We believe that someone starting to
consider investing in equity should seriously look at an index fund. One can later
on graduate to an actively managed fund and only later to buying stocks
directly. Investing in equity index fund is a simpler task and carries less
risk as compared to the other alternatives.
Now first of all, let us understand the meaning of “less risk”.
Equity as an asset class is considered to be risky since the prices are
volatile. This would remain so irrespective of whether one invests in stocks
directly or in an actively managed mutual fund or in an equity index fund. The
risk of volatility does not go away. However, the volatility is at two levels –
one at the stock level and the other at the market level. Investment in any
diversified portfolio – whether actively managed or index – removes the risk of
individual stock level volatility through the process of diversification. The
market wide volatility does not go away. This is a risk that cannot be reduced
or removed through diversification.
That said, an index fund is supposed to mirror a benchmark index.
This means the index fund would ideally (or at least theoretically)
carry the same level of risk as the index. This means one of the measures of
risk we discussed about earlier – standard deviation – would be (once again, at
least theoretically) the same as that of the index and the other – Beta – would
be one.
Also the returns from the index fund should be equal to that of an
index less the expenses charged.
As explained, the risk and the return from the index fund should be
the same as the index. However, in reality it may not be. This is exactly what
we need to measure. Does the index fund behave the same as the index? Does it
track the index properly? If not, what is the “tracking error”?
Tracking error attempts to measure the deviation in the risk-return
profile of an index fund compared to its index.
The reasons contributing to the tracking error are as listed below:
·
Expense ratio
o
The index value is calculated
considering the closing values of the stocks it comprises of, whereas an index
fund’s NAV would be calculated after deduction of management and other expenses
from the total value of all the holdings. This expense ratio would mean the
fund should underperform the index it tracks.
·
Bid-ask spread and the
transaction costs
o
The index value is calculated
using the closing prices of the stocks in the portfolio. However, when the fund
transacts in the market, either to buy or sell a stock, the transaction happens
depending on the price at which there are buyers or sellers present. There is
always a difference between the prices offered by the buyers as against the
sellers. This spread results in the fund paying more while buying and getting
less while selling.
o
At the time of a transaction,
the fund has to pay certain charges, e.g. brokerage. This is an additional cost
resulting in reduction in performance.
·
Time of transaction
o
The fund would buy or sell the
stocks during the day, whereas the index value is calculated based on the
closing prices. Most fund try to transact closer to the time of closing of the
market to reduce this difference.
·
Cash held in the portfolio
o
In order to service redemptions
as well as the delay in deploying the money received from new investors result
in the fund holding some cash in the portfolio. This cash behaves differently
from the portfolio of stocks. This again results in performance difference.
·
Dividends declared by companies
as well as other corporate actions
o
Companies pay dividends, which
are received by the fund. However, the fund may choose not to pay the dividends
to its unitholders. Similarly, the fund may also offer growth option, in which
the dividends are not paid. The index values are calculated without factoring
the dividends.
o
Various other corporate actions
would also mean the fund performance may differ from the index.
·
Changes in the constitution of
the index
o
When the index constitution
changes, the fund has to make changes accordingly. All the transactions result
into some costs. These costs put a downward pressure on the performance.
Given the above discussion, one must look at the tracking error of
an index fund – in fact, that is the only thing one needs to look at. Lower the
tracking error, better is the fund – as it remains true to the label. Higher
tracking error means the fund is not properly tracking the index.
While most of the factors contributing to the tracking error are
very difficult to measure, the one factor that must be considered is the
expense ration charged by the asset management company. This number is
mentioned in the fact sheet of the fund. Here again, since all expenses are a
drag on the performance, lower the expense ratio, lower would be the tracking
error and hence better the fund.
