S&P 500 Q3 earns likely to turn negative Thursday - Thomson Financial

Marketwatch reports:

Third-quarter earnings of S&P 500 companies have "a good chance" of turning negative for the first time in five years on Thursday, after factoring in Wednesday's profit-warnings from a slew of energy stocks, Thomson Financial said.
"There's a good chance that we'll go negative tomorrow," said John Butters, analyst at Thomson Financial, which tracks earnings estimates at S&P 500 companies.
