Check out which companies are making headlines before the bell:
JPMorgan Chase—The bank earned $1.54 per share for the second quarter, beating estimates by 10 cents, with revenue also slightly above forecasts. The bank's results were helped by a rebound in its mortgage business compared to the prior quarter, and a drop in legal costs.
Coca-Cola—UBS upgraded the stock to "buy" from "neutral," citing an increasing probability of a breakout in the next year. Among other factors, UBS thinks the company will benefit from favorable trends in both pricing and productivity.
