Volatility continued Friday, with Dow futures swinging wildly. Dow stock Chevron fell nearly 3% in the premarket, retreating from a record after an earnings miss. Apple, also a Dow component, was a bright spot in what's shaping up to be another dismal day, rising more than 2.5% in the premarket following strong earnings. Nasdaq futures actually turned positive. (CNBC)
