[R-SIG-Finance] Dividends

Although, in theory it should change the underlying the same as the option, evidence that the calls change by the after-tax effect.  In my experience it is always best to go by the actual market traded instruments, so I would use the dividends.  If you see it differently, please explain.

This is not an R-related question so pls excuse. If I am backtesting a
hedged* options portfolio then do I need to take dividends into
consideration? My understanding is that since dividend affects both the
calls and the underlier in a similar fashion then taking dividends also into
consideration for backtesting will skew the effects on the returns. Please
correct me if I am wrong?

Many thanks
