You know that political bumper sticker that goes, "If you're not outraged, you're not paying attention"? It might as well apply to the market these days. Starting in November 2007, stocks started dropping ... and they haven't recovered.

Good -- even great -- companies are being sold down to levels far below their true worth, and investors are losing their savings. It's outrageous!

A shocking and somewhat interesting statistic
A whopping 88% of all stocks traded on the major U.S. exchanges were down in 2008. That's 5,369 names in the red. Of those, 4,407 dropped 25% or more -- a list that includes Target (NYSE:TGT), DISH Network (NASDAQ:DISH), and Merck (NYSE:MRK).

So if you've lost money of late, don't feel bad. There's been no hiding from this downturn.

But let's also be honest: It hurts.

Time to panic-sell
It's outrageous, and it hurts, but what's the individual investor to do? The market is a monolith at times, and it can be hard to sway.

Case in point: Barrett Business Services. I found this tiny West Coast professional-employer organization and staffing company during my work as the micro-cap analyst for our Motley Fool Hidden Gems service. At the time, it was trading for a little more than $15 per share. I liked the CEO, I liked the balance sheet, I liked the track record, and I thought it looked cheap. So I bought it.

What happened next was frustrating: It dropped to $14, then to $10, and after a brief resurgence, now all the way down to $8 and change.

What's your next move?
See, the market has it in its head that the economy is worsening and the consumer is weakening. When fears are that broad, everybody gets punished.

Pain isn't reserved for companies that struggle to turn a profit, such as Advanced Micro Devices (NYSE:AMD), or solid companies that had been quite overvalued, such as Research In Motion (NASDAQ:RIMM). Even "defensive" plays like Pfizer have been stung (both before and after it decided to spend a lot of its balance sheet to acquire Wyeth (NYSE:WYE)).

But back to Barrett: It still has a strong balance sheet, it has increased its share repurchase program, and it's paying shareholders a nice 3.8% dividend. The company has also gained market share and improved its client list as competitors have gone out of business. Could the stock drop further from here? Of course, but it will be among the first to rebound if the economy improves. And no matter what, it's still outrageously cheap.

And I'm not alone. CEO Bill Sherertz told analysts on a recent conference call: "If you guys want to sell [the company] down to five times earnings, maybe I will just buy the whole [expletive] thing."

Enough said
Our goal as small-cap investors is to find stocks like Barrett -- fundamentally strong companies that the market has oversold. Then we buy and wait until the market recognizes its mistake. Sometimes, in Barrett's case, we get to buy more as the stock gets cheaper.

And though the market came to its senses with Barrett's recent earnings report, there are a few thousand more stocks on the market that have been sold off substantially over the past year. I know of a few more that look outrageously cheap. That's why I continue to put money to work in the market.

Tim Hanson owns shares of Barrett Business Services. Pfizer is both an Inside Value recommendation and a former Income Investor pick. The Fool's disclosure policy is awesome.
