You need to do the math before you can determine whether a tax loss sale is warranted. I'll give you an example to illustrate that your statement may not be accurate. Say you bought $10,000 worth at .08 (I'm sure many are in much higher). That $10,000 is now worth $1,000. If you're in the 33% tax bracket, taxes on that $9,000 that could be offset by selling would be $3,000. In other words, hemi would have to triple from here just for you to break even... and that doesn't even consider that you've still got to come up with the $3,000 for the taxes if you don't sell.
On the bright side, I don't believe the market will see much tax loss selling this year... most have already lost any profits they had. What we will see is people selling the more highly speculative plays to buy the big board bargains, not that they're not equally risky in this environment.
