Check out which companies are making headlines before the bell:
Morgan Stanley—The firm earned an adjusted 85 cents per share, beating estimates of 78 cents, with revenue also above forecasts. Morgan Stanley's results were helped in part by better-than-expected performance in investment management and fixed income.
Hasbro—Hasbro reported quarterly profit of 21 cents per share, swamping estimates of 8 cents, with revenue also beating forecasts by a wide margin despite the negative impact of the strong dollar. Hasbro saw particularly strong performance in its Transformers and pre-school units.
Halliburton—The oilfield services company beat estimates by 12 cents with adjusted quarterly profit of 49 cents per share, with revenue scoring a slight beat as well. But Halliburton does say it expects the oil sector to remain "challenged."
SunTrust—The bank earned 78 cents per share for its latest quarter, 6 cents above estimates, with revenue essentially in line. SunTrust was helped by lower expenses, and growth in noninterest income.
