There were several pieces over the weekend which argued for a rebound. Barron's ran an article (subscription required) arguing that some cash rich companies look attractive. CBS Marketwatch ran a story that said Google and Cisco don't have mortgage market exposure and that the tech sector looked interesting.
I will add this word of caution. Warren Buffet said, "When others are greedy I try to be fearful, and when others are fearful I try to be greedy." Well, right now there is a lot of fear. However, there is also a ton of volatility. I don't think we're out of the woods yet by a long shot. And until we are, expect more extreme market gyrations.
In other words, if you're going to move into the market, there are some good fundamental reasons to do so. But make sure you can take the ride we're probably going to have in the next few months.
