Kidd Mark EVP, GM Data Centers & ALM Sell 10b5-1 6,000 $115.60 $693.6K 95,507 −5.9% of holding

Form 4s are due within two business days of a transaction, so this is close to real time — unlike the quarterly 13F data on the Institutional tab. A single large sale often reflects a prearranged 10b5-1 plan rather than a fresh view, so read a pattern of sales rather than any one of them.
