Major averages kicked off the week in fine fashion Monday, ending with solid gains. Commodity stocks outperformed thanks to a big rally in China stocks overnight. The Dow Jones industrial average outperformed, rising 1.4%, led by Caterpillar (CAT) and Apple (AAPL). Apple got a lift after two analyst reports said recent bearish sentiment in the stock was overdone. The S&P 500 picked up 1.3% and the Nasdaq gained 1.1%.
