2) A covered call is exactly equivalent to a cash-secured naked put, when the strike prices and expiration date are the same.
3) Naked put sales (cash-secured or otherwise) are still okay. But they should be used ONLY by investors who WANT to accumulate stocks at prices lower than current.

Hi Mark,
Since you seems to give helpful and useful advices, just my two cents. (I think it's what you thought but didn't write
)A covered call can be seen as a naked put only for european style options. Be careful with indexes and stocks.
Since one can't know when american puts or calls with the same strike and the same expiration date would be exercized, they can't be held as if they got same maturity. Call put parity holds no more and inequality we get then is something quite different.
Regards
