If you buy anything, make it something that’s going up that you can put a tight stop in. Then you’ll have the potential for unlimited upside and a teensy downside. You won’t loose much money. The stock market is still overpriced right now and (I believe) we’re just beginning the last of several huge dips. In a deflationary period, EVERYTHING looses value. I also believe this will (is?) happen. Therefore, if the cost of goods and services goes down more than the value of the dollar, you’re actually “making” money by not loosing any.
On the other hand, I keep buying and selling Apple (AAPL) fool that I am, each time swearing I’ll never sell it again. If you had a gun to your head and had to purchase a stock, Apple is a real good bet.
