Monday's US session is underway. Here are the S&P 500 stocks drawing the heaviest trading volume today.

US equity markets opened a fresh week Monday with investor attention locked on the most actively traded names inside the S&P 500, as traders position themselves amid ongoing macro uncertainty and sector rotation. Volume leaders often signal where institutional money is flowing and can set the tone for broader market direction throughout the week.
