The stock is down $2.44, or roughly 4.5 percent, to $51.56.
The claims, that Moonves harassed six women over decades, surfaced Friday in a report from the New Yorker. The CBS chief has been a prominent figure in television for decades, credited with turning around a network that had been mired for years at the ratings bottom.
Among other things, Moonves has had a knack for picking hit shows like “Survivor” and “The Big Bang Theory.”
The drop in CBS shares follows a 6 percent decline on Friday when the report first surfaced.
