The thing here to remember is that the market is based on a risk/reward quantative. If we worry today about what may or may not happen,it will hinder enjoyment of life. Might I suggest investing as much as you feel comfortable with(I had to learn this also) and try to diversify your portfolio,when allowable. Putting all one's eggs in a particular basket works only some of the time and falls on the riskier side of investing. KBLB....more than just a ticker symbol.
