If you shorted the stock (even in a nice, frictionless theoretical work) the vol drag still works against you, because it's a quadratic term (i.e. it is not sensitive to sign) In the real world you would lose money even faster because *gestures at real-world frictions*

It’s the negative of a quadratic, so you can flip the sign
