Over the last 130 years of the stock market, one thing has remained constant: if the rate of inflation is between 1-3%, the stock market generally returns about 13% per year. In years where inflation rises above 3%, the market usually returns an average of under 3%.
So, keep an eye on the job Bernanke (the Federal Reserve) does. If he continues to keep inflation in check, it's a good time to pump the market. But watch closely - it can change quickly.
