Insider trades: Microsoft, Taiwan Semiconductor, and Snap among notable names

Between May 18–22, insiders at major companies disclosed notable buy and sell transactions that may influence investor perception and short-term share demand. Microsoft (MSFT.OQ) saw disclosures from EVP Amy Coleman, while Taiwan Semiconductor insiders also sold shares. The largest single move was a $317M insider sale at CVS Health, with most insiders trimming positions; smaller purchases included AMC’s CEO ($344,350) and Rivian ($251,460). ServiceNow and Snap insiders reduced stakes materially, while some TSMC insiders (Bor‑Zen Tien) increased holdings. Markets reacted only modestly intraday (MSFT quoted near $418.57), and the piece frames these trades as mixed signals—broad selling by insiders but selective buying—likely producing limited, short‑term impact on liquidity and sentiment rather than signaling fundamental shifts.
