Volatile stock market waits for earnings clarity

Wall Street seeks positive end to ugly month

The U.S. stock market is on track to end the first month of the year with losses as investors reassess what's ahead for public companies impacted by the decline in energy costs, a stronger U.S. dollar and weaker global economy.

"Clearly right now the discussion is all about earnings, especially companies talking about overseas demand, and currency issues facing multinational companies," said Mark Luschini, chief investment strategist at Janney Montgomery.

With just over 140 companies reporting this week, Wall Street is hearing from a fair amount of companies pinning lowered guidance on the dollar's strength and lackluster demand overseas.
