There's no doubt that 2010 has been a rough year for investors. First the BP oil spill, then the sovereign debt crisis in Europe, followed by bad payroll reports and stagnant unemployment. The robust recovery we saw in 2009 has all but disappeared, replaced with an up-and-down market that can seem unnerving at best, and simply irrational at worst.

As you can imagine, investors have been heading for the equity doors and into the bond room. Billions of dollars have gone into bonds or bond funds so far this year, and unfortunately, much of that money has come at the expense of equity funds.

Academics and investors alike have pointed to the last decade as proof that buy-and-hold investing is dead, and that the equity premiums we once saw are only a present-day myth. In my opinion, that's just crazy talk. Of course, now is an easy time to call it quits on investing -- the market is volatile, there's lots of uncertainty, and it seems like all the news and recent headlines have been nothing but negative.

But give up on investing? I don't think so.

Nevertheless, it is seriously worth the time to evaluate your portfolio in order to see what stocks are going to keep you up at night, and which ones may let you sleep sound. In this series, I've identified the top seven tech stocks that have extreme volatility, are trading way below their 12-month highs, yet still have the coveted 5-star ranking of our 165,000-strong CAPS investing community.

Our crowd of Foolish investors has a good track record of identifying stocks that can outperform the market, and 5-star stocks often follow that path pretty well. However, these seven stocks have taken investors on a roller-coaster ride.  

If you own them (or are thinking of buying them), make sure you're comfortable with that volatility, and make sure to do your own due diligence to determine whether these tech stocks have what it takes to bounce back.
