Bank of New York Mellon shares are under mild pressure in after-hours trading following a broader market reaction to economic data. While the company saw recent institutional interest with new stake acquisitions by Bank of Nova Scotia, Galaxy Digital Capital Management, and Evolve Private Wealth, these filings do not provide a catalyst for the current move. Instead, the stock appears to be tracking a wider market trend as major indexes eased following July PCE inflation data that arrived slightly hotter than anticipated.
