Context
These were compensation awards (restricted and performance RSUs), not open-market purchases or sales. RSUs/PSUs are contingent on time- and/or performance-based vesting; they represent the right to receive shares in the future if conditions are met. Such awards are common executive compensation and do not by themselves indicate a buy or sell signal in the market.
