I made a wage a year where I should be able to buy a house in about 12-18 months from today. The investments would just help make that happen faster, allow me to buy a better home, or just let me have money after I buy a home.
If you're looking at least a year out, buy any decent, non-financial company. Of course, that's if you buy into a 2010 recovery. Personally, I don't. If you don't think we're going to see a true recovery by 2010, then now is not the time for long term investing. You can double your money in a year with a little work, but it's going to be with active trading, not buying and holding.
Most importantly, DON'T buy anything right now. We're waaaay overbought, the market is being floated by only god knows what artifical means, and the next crash will happen. Wait for that day that's solidly into the next big downturn when everyone starts talking about the end of the world, no hope of a recovery, news is just getting worse and worse, and throw all your money at any big name that's taken a beating.
