The markets are down again today. The selling is not massive but it is the third drop in a row. The SPDR S&P 500 ETF (NYSEARCA:SPY) is trading at $121.79, -1.32 (-1.07%). The big driver to the downside today is clearly commodities. Almost every single commodity is dumping sharply. Everything from oil to gold and silver. While these drops are massive, smart investors and traders are starting to look for the buy level.
