What part of the article gave you that impression?
This article makes me thing he picked the share amount in October.
Under the SEC’s 10b5-1 rule -- designed to help avoid accusations of insider trading -- executives can set up plans to sell a pre-determined number of shares at pre-determined times. Krzanich has been doing so since at least 2015. But his latest sale coincided with revelations that all modern processors can be attacked, potentially exposing crucial data, such as passwords and encryption keys. The news sent Intel shares tumbling last week.
Two other things also attracted attention. Krzanich changed the timing of his trading instructions. In 2015, 2016 and 2017, his sales instructions were issued in June, April and February, respectively; however, this past October he issued a new set of instructions. Plus, he sold thousands more shares last year than in previous years, though the sale coincided with the biggest payout of performance-based shares he’s gotten since at least 2012.
