Have you ever listened to an interview with a supermodel?

And no, I don't mean watched an interview, I mean listened to one. Almost invariably, the supermodel recalls her awkward years in high school. Occasionally, the years were so awkward she didn't get asked to prom.

It wouldn't have taken a Casanova to score a date with a supermodel back then. Years later, even Casanovas get turned down.

It's this same kind of bad timing that can kill your portfolio's returns.

The supermodel stocks
Since my job is analyzing and writing about stocks, I talk to a lot of people about stocks -- from folks who can barely spell the ticker symbol to folks who have multi-tab spreadsheets on each company they follow. But this motley assortment has one thing in common.

Everybody, and I mean everybody, has an opinion on Apple (NASDAQ:AAPL). And Wal-Mart (NYSE:WMT). And Google (NASDAQ:GOOG). And the other supermodel stocks as well.

The problem is that they're kinda late to the party. Wall Street is all over these companies. Apple has 44 analysts covering it, Wal-Mart has 26 and Google has 38.

To be clear, those analysts cover these companies and their industry competitors as a full-time job -- they're laser-focused on knowing everything they can about just a few companies. While you're making toast in the morning, they're updating proprietary models. When you're meeting with your boss, they're meeting with CEOs. Printing out one of their research reports will get you on the Sierra Club's watchlist.

You get the idea.

Wall Street's weakness
Now, that doesn't mean you can't make money on these stocks. Wall Street is known for following the herd and thinking in quarters instead of years. You can surely exploit these Wall Street weaknesses. Heck, that's what we try to do every day at the Motley Fool.

However, focusing just on the big guys misses Wall Street's biggest blind spot. Analysts are very well compensated, so covering the little guys -- the ones fewer people have heard of -- just doesn't make sense from a cost-benefit perspective.

And that leads to opportunity for the individual investor (read: you).

Just look at the differences in the amount of coverage the following stocks receive:

Small, Underfollowed Stock

No.  of Analysts

Well-known Stock

United Health (NYSE:UNH)

Ameristar Casinos

MGM (NYSE:MGM)

Las Vegas Sands (NYSE:LVS)

18

Dawson Geophysical

ExxonMobil (NYSE:XOM)

Schlumberger

Twice as many professional analysts follow the Vegas lights of MGM and Las Vegas Sands than Ameristar, which stays in the shadows by operating in places like St. Louis and Kansas City. It's even more lopsided for Dawson Geophysical and inVentiv Health.

Keep your eyes open
Now, just because a company is underfollowed doesn't mean it's a diamond in the rough just waiting to be discovered. In fact, there are plenty more bad, unfollowed companies than good.

The trick is to do the work that Wall Street either can't or hasn't yet.
