If you think AAPL goes down, you should have bought a put, not a call.

Buying a Call -> betting stock goes up

Buying a put -> betting stock goes down




ok - i get that at last, thanks - It's true no matter what option strike price i select for the CALL option!

In fact, here's a summary of it all IMHO:



CALL formulas:

Let's say at time t=o:

I buy an AAPL CALL at STRIKEo option at the price BIDo

I buy 100 shares of AAPL stock outright at the t=o market price AAPLo




Then at time t:

PROFIT(t) = 100(AAPL(t) - BIDo - STRIKEo) { if I 'excercise' the contract at time t} or

PROFIT(t) = 100(BID(t) - ASKo) { if I 'sell' the contract at time t}



PROFIT(t) = 100(AAPL(t) - AAPLo) { just sell the stock at time t - no options}

And similar formulas for the PUT options, where i'd invest had I hoped that AAPL goes down.
