qwik - I believe the usual interpretation of "essentially the same" security would NOT match up INTC and AMD. They are different securities for purpose of the wash sale rules, even though they might be price correlated.
However, if you dumped INTC and bought INTC calls, then you could run afoul of the wash sale rule because the calls are essentially the same security in that the calls can be exchanged for the equity.
