Ok, it is Friday 8th Feb. 13:40. AAPL is falling nearly to 122. Its time to catch this knife. In fact I did it but just with 100 shares, because altgouhg I believed that during same day will be chance sell it as minimum for breakeven, but if I bought more for example 500 shares and it will stop just at 120 my balls are not enough big handle it, I know myself - and I will sale it at that moment for big loss and than see how it moves to big profit without me. My question. If I want risk exactly at same time $1000 purchasing long call with intention keep it until underlying will "kiss" 128 which strike I should use? (I am ready lose half of or even more). At that time 128 was possible at same day if exceptionally lucky, but more probably just in 2-3 days. I know, I know, not to daytrade options, but if underlying is moving $6 I hope we can make small exception. My question - which strike I should use, which has best bang for a buck? And which month? I assume front month although the expiration is close? And for example if expiration will be in just 2-3 days still use the front month? I know, that deep ITM options are moving with underlying, but for 1000 bucks I will not purchase lot of them - not speaking about bigger spreads. Thanks for any suggestion. Where I can find some literature or web advice about this problem, eventually how to calculate it? What was the best way to go at that moment, when I was ready risk for example 800 bucks but not more? And do not suggest to me tight stop with 20:1 prop leverage, I can not use it.
