The two supplied records do not describe the same underlying event. NetApp Inc. shares may move 9.7% when the technology storage company reports earnings on Sept. 2 after the market close, based on Bloomberg-compiled options data. NetApp exceeded its options-implied move in three of its past eight reports, including a 46.5% gain on May 28 versus 9.4% implied. The newer record concerns Ciena Corp., whose shares may move 9.4% after earnings on Sept. 3 before the market opens; Ciena exceeded its options-implied move in six of its past eight announcements.
