Investing in small-cap stocks can be an emotional roller coaster, especially in a market like this. Small caps provide both the market's best returns and its worst. They have the most room to run, but also the smallest margin for error. And extreme daily volatility with little news is not uncommon. Clearly, small-cap investing is not for the faint of heart.
But in spite of the inherent risks, the growth potential of small caps is just too good to ignore. That's why many investors use a small-cap mutual fund or exchange-traded fund (ETF) to get their exposure to this capricious segment of the market.
And that's fine for most people. The important thing is that you have at least some small-company exposure in your portfolio. If you don't, you may be missing out on substantial growth opportunities. For instance, the Vanguard Small-Cap Index Fund (NAESX), which tracks the broad small-cap market, returned 8% per year over the past 10 years, while the Vanguard S&P 500 Index (VFINX) returned roughly 3%.
So even if you had just 20% of your equity portfolio allocated to the small-cap index fund, you would have improved your ten-year returns quite nicely.
You can do better
While a mutual fund or ETF will diversify your small-cap holdings, it can also dampen the growth potential of your portfolio.
For one thing, the fund could be spreading your investment across too many stocks. The Vanguard Small-Cap Index, for example, holds 1,742 stocks. The fund's top holding, Alpha Natural Resources
Secondly, many small-cap fund holdings lean toward the mid-cap range of $1 billion to $3 billion, which prevents investors from truly benefiting from small-cap exposure. Consider that the average market cap of the Vanguard Small-Cap Index is $1.4 billion, which is closer to the mid-cap arena.
Now, while these mid-cap stocks could end up performing well for investors, they naturally have less room to grow than does a smaller company capitalized at $200 million, or even $500 million. In other words, a stock's multibagger potential tends to diminish as the company gets bigger.

Instead of looking for companies that have already experienced tremendous growth, Motley Fool co-founder Tom Gardner and the Hidden Gems small-cap investing team look for companies the market hasn't discovered yet.
