In investing, three truths are held to be self-evident:
1. Investors should buy low and sell high;
2. Investors should not be propelled by panic;
3. Investors should not assume past performance guarantees future results.
Or at least that's what everybody says. What fund investors actually do is another matter entirely. They are often fickle, buying funds that have done well (or buying high) and selling in a panic when they stall (that is, selling low). In doing so, investors sabotage their own results. Here's what not to do.
The tale of PBHG growth
A classic case of buy high and sell low is PBHG Growth. From 1992
through 1995, the fund quietly built a superb record, though it wasn't
attracting a lot of attention (or cash inflows) from new investors. In
early 1996, when the fund's average three-year gain of more than 30%
placed it on many a leader's list, the money started rolling in. Nearly
$2.5 billion poured in during the first six months of 1996, just in time
for the fund's 10% slide in July. New money slowed. Then, in early 1997,
after the fund had suffered several months of losses, shareholders
started bailing out, missing a strong second-quarter rebound.
History repeats itself
Although few funds have cash-flow stories as dramatic as PBHG Growth's,
Morningstar studies have found that investors across all fund types—both
stocks and bonds—have paid a price for being fickle.
The damage is greater on the stock-fund side, especially with aggressive funds, in which volatility and temptation are highest. In the small-growth category, for example, one Morningstar study found that investors had surrendered 1.8 percentage points annually by chasing performance rather than by simply investing a little each month, or pound-cost averaging. It's not surprising that the small- and mid-cap growth categories have been land mines for investors. It's easy to get caught up in the excitement of a go-go fund's performance. Don't-don't.
Clearly, emotion has a way of interfering with reason. That's why pound-cost averaging can be such a good idea. Sure, it's possible to make more money with a lump-sum investment. But it's also possible to make less.
The lessons
What can fickle fund investors teach you?
Discipline generally pays: Because emotions and hype can get in the way of smart investing, systematic pound-cost averaging is a sound strategy. Granted, investing a lump sum in the market as soon as you have the cash can be a good approach when the markets just keep going up, or when you are certain you won't give in to the temptation to buy or sell at the wrong time. But in many cases, the pound-cost averager is going to beat the willy-nilly investor.
Don't try to navigate a minefield: Discipline is particularly important in riskier areas, in which the hope for big gains and the reality of big losses can tempt even well-meaning investors into making trading blunders. If you invest in aggressive funds, promise yourself you won't back out when returns head south. If the manager and strategy that you originally bought are still there, you should be too.
Don’t chase funds: Of course, even levelheaded, systematic investors need to alter their portfolios from time to time. When moving money or picking new funds, resist the temptation to chase performance. If anything, invest in areas everyone else is ignoring.
