The Dow Jones Industrial Average (DJI) is pointed modestly below breakeven this morning, as investors take a wait-and-see approach to a week dominated by quarterly reports. "Earnings season kicked into gear last week, and the S&P 500 Index (SPX) closed on the high for the week, and also notched a new five-year high," said Schaeffer's Senior Options Strategist Tony Venosa, CMT. "This morning keep an eye on the homebuilders, as existing home sales will be reported at 10:00 a.m. ET. Earnings continue to roll in, and we will hear from Verizon (NYSE:VZ) and Johnson & Johnson (NYSE:JNJ) before the bell, while Google (NASDAQ:GOOG) and IBM (NYSE:IBM) are on tap to report after the close."
