Apple's earnings report impacts stock options and market performance.

A stock options strategy called a straddle is priced for Apple's stock to move $7.02 in either direction on Friday after the company reports its fiscal Q2 results. This is slightly more than the average one-day post-earnings move of $6.68 over the past 12 quarters. The straddle's pricing is based on 30-day implied volatility for Apple's stock of 30.3%, which compares historical volatility over the past 90 days of 26.1%.
