No, I don't think they do in most boards, unless the board members are individually dangerously exposed to drops in the stock price (Elon Musk cough). Apple more so than most other companies, is famous for taking the long view strategically, so I would be very surprised if drops in the share price in and of itself would cause them to alter their strategy. They haven't any of the previous times in the last two decades, when the stock dropped significantly.
