Sliding further

Stocks skidded to a lower close, as investors remained wary ahead of Q2 corporate results and another eurozone meeting. Industrial and energy shares led the declines. 63 out of 103 companies lowered projections for earnings. There's a concern that the European slowdown has made its way to the U.S. Aluminum producer Alcoa reported second-quarter results in line with analysts' expectations, and shares moved up slightly in after hours trading. The implied volatility inched higher as market fears surfaced again.
