(CNBC) Investment firm SkyBridge Capital, whose founder Anthony Scaramucci briefly traded Wall Street for the Trump White House, told clients that its co-chief investment officer resigned. Troy Gayeski, who has overseen the $6.5 billion firm’s activities as co-chief investment officer since 2019, left SkyBridge this week to “pursue other opportunities,” Scaramucci wrote in a letter to clients that was seen by Reuters.
