Have you actually tracked the difference in spread/slippage between manual vs. automatic rollover? I'm curious if the perceived disadvantage is always a real one in terms of net cost.

It really depends on the underlying. For some highly liquid names, you might get a bit more follow-through. But for most NDX components, the juice isn't worth the squeeze after the initial earnings reaction. I usually just take my profits/losses and move on.
