Active versus Passive Investment
Investors who believe in the efficient market hypothesis
would argue on behalf of the passive investment
style. If stock prices reflect all relevant information and stocks are
always priced at their intrinsic values, it would be difficult for
investors to beat the markets over long periods. Consequently, if
investors cannot profit from insider information and there are
no undervalued stocks, they have two alternatives: (1) invest in
market indexes or (2) choose individual stocks and hold them for
long periods. These are known as buy-and-hold strategies.

Asset Allocation of Stocks by Style

Indexing
Those who subscribe to index investing believe that events affecting
companies occur randomly. Therefore, investors have a 50–50 chance
of being correct in picking stocks that will go up; hence their odds
of beating the market become more muted. Consequently, these
investors are satisfied with the returns of the market and would
invest in the stocks that make up the market indexes. This strategy
can be achieved in the following ways:
* Investing in the individual stocks in the index, for example,
the 30 stocks in the DJIA. However, investing in the 500
stocks of the Standard & Poor’s (S&P) 500 Index is not practical
for most individual portfolios. Investors could invest
more easily in sectors of the S&P 500 Index, such as the
technology sector or the financial sector, or the “nifty fifty”
stocks, or the Dogs of the Dow.
* Investing in index-tracking stocks (exchange-traded funds),
which underlie the indexes. Examples of these are the SPDRs,
which track the S&P 500 Index and the sector SPDRs of the
S&P 500 Index; the DIAMONDs, which track the DJIA; and
the Nasdaq 100 tracking stock, which invests in the largest
100 companies in the Nasdaq.
* Investing in index mutual funds.
An examination of the results of index mutual funds versus
the actively managed mutual funds, as a proxy of passive versus
active investing, makes the case for indexing more compelling.
Tergesen (1999, p. 110) reported that the average S&P 500 Index
mutual fund earned around 18 percent annually over the 10-year
period 1989–1999 as compared with 16 percent annually for the
actively managed equity mutual funds. This 2 percent annual
difference may not seem all that significant, but when this difference
is compounded over time, the results point overwhelmingly
toward indexing. Over a 10-year period, the compounded returns
of index funds exceeded those of actively managed equity funds
by about 80 percent (Tergesen, 1999, p. 110). More recently, according
to Burton Malkiel, a finance professor at Princeton University,
the S&P 500 benchmark index fund outperformed 84 percent of
actively managed large-cap funds during the 10-year period
1993–2003 (Farrell, 2003).
There are a number of reasons to explain the advantages of
indexing over actively managed mutual funds:
1. Actively managed mutual funds may keep some money in
cash, anticipating a downturn in the market. If this does
not materialize, then index funds will earn more from their
holdings because they are always fully invested.
2. The annual expense ratios of index funds are considerably
lower than those of their actively managed equity mutual
fund counterparts. Index funds do not change their holdings
unless the stocks in the indexes are changed. Actively
managed funds can experience high turnovers of their
holdings, which means higher transaction costs.
3. Large-cap stocks, which are followed by many analysts, are
probably efficiently priced, which gives index funds an
advantage over the stock picker.
The opportunities for active managers and stock pickers are
in the small-cap and international stocks, which may be underfollowed
by the analysts. Similarly, in a market downturn, active
managers can put limits on the decrease in their funds’ stock prices
by raising cash or investing in defensive stocks, which may not go
down as much as the fixed portfolios of the index funds. This is not
to say that actively managed portfolios will not go down in a bear
market. These portfolios will go down just like the index funds, but
steps can be taken to reduce the amount of the decline in their
value. This can be seen where small-cap equity managers have outpaced
the Russell 2000 Index by including some large-cap stocks in
their holdings. Other studies confirm that active managers do not
consistently outperform indexing (Martin, 1993, pp. 17–20).
Buy-and-Hold Investing
Besides indexing, the other passive investment strategy for stock
pickers is to buy stocks for the long term and hold them. In other
words, investors would hold these stocks, making minimal
changes over time. Performance between active and passive strategies
is more difficult to evaluate because this depends on the
composition of the stocks in both active and passive portfolios.
However, using index funds as the basis for buy-and-hold investing,
the results confirm that active portfolio managers do not
outperform the buy-and-hold strategy. Jensen (1968, pp. 389–416)
surveyed 115 mutual fund managers during the period 1945–1964
and found that the average returns of these funds were less than
investments in a portfolio of Treasury bills and the market index
would have returned.
Market timers often tout how they were able to exit the market
successfully before a crash and then reenter the market at a
lower point to increase their overall returns. This may be easier
said than done. Research done by T Rowe Price showed that in
order to do better than a buy-and-hold investor, market timers
would need to be accurate in more than 70 percent of their calls to
enter and exit the market. A study done by Nejat Seyhun covering
the period 1963–1993 found that an investor who exited the market
for just 1.2 percent of the market’s best-performing days would
have lost out on 95 percent of the total returns (Strong, 1998,
p. 363).
There certainly appears to be a disconnect between the research
results as reported from the ivory towers of academia and the communications
and hype as reported from many people on Wall Street.
The growth of newsletters forecasting the precise future movements
of the markets and how to time them is on the rise as more investors
enter the stock markets hoping to double or treble their money over
a short period. As of this writing, the clairvoyant with 100 percent
accuracy in calling the markets has yet to emerge. Until such time,
the odds are stacked against timing the markets; they favor the
buy-and-hold investor.
What becomes apparent is that it is difficult to beat the markets
consistently over long periods regardless of the method. This
theory certainly lends support for buy-and-hold strategies over
market timers. In addition to those reasons already discussed, several
reasons put forth for the underperformance of active investing
over passive investing include
* Active trading means higher transaction (commission)
costs.
* If the holding period for stocks is less than one year, the gains
incurred are taxed at higher Federal tax rates than those
of the longer-term holding periods of the buy-and-hold
investors.
