There were 512 unusually active call options in Wednesday's trading. I define these call options as those with Vol/OI ratios of 1.24 or greater and expiring in seven days or more.
The Microsoft (MSFT) Feb. 21/2025 $470 call, with a Vol/OI ratio of 84.75, was in the second spot. Its volume was 32,545, which is reasonably high given its 30-day average volume of 252,618.
