If I was younger, and had an extra thousand or two or three socked away for the distant future, I'd buy stock in anything that people have to buy (e.g., food). The price can only go up from here. The prices may not hit absolute bottom today or tomorrow, but probably very soon.

The only stocks to avoid would be for products that might conceiveably become obsolete with the advent of new technology, especially "green" tech and alterntaive energy. But even in those fields, the biggest corporations are fairly sure to diversify and figure out ways to make profits even if they have to shift gears.

For example, the giant oil companies will probably be able to gradually phase out of oil ~ only after they absolutely have to ~ and start profiteering with natural gas, wind and solar equipment, etc.
