U.S. stocks had their biggest decline in two weeks, probably making May the worst month in three years, after consumer confidence declined, oil prices rose and Wal-Mart Stores Inc. struggled to meet its sales forecast.
Today's biggest losses came in the Nasdaq and Small Cap stocks as well as basic materials stocks. Emerging markets lost another 4.0% on average. This shows that investors are still selling their riskier holdings and moving some money to the sidelines.
