He’s telling you to sell them, not buy them though. Basically, if you wanted to sell 100 shares when it hits $140 again, you could just sell a covered call at a strike price of $140 with months until expiration, and get paid while you wait for it to hit the price you were gonna sell at anyways. Or it doesn’t hit $140 by then and you keep your shares and the money you got for selling the call.
