Let me break down a losing trade you likely did.
The one most people make.
You buy a call on a great company. 3 weeks out. Paid $500.
Week 1: stock drifts down 2%. Your call is down 30%. You're confused because 2% isn't much of a downward move for the shares.
Week 2: stock recovers, closes higher than when you bought. Your call is still down 20%. Now you're really confused.
Week 3: stock closes up 4% on the month. Your call expires worthless.
You were RIGHT about the company. You were right about the direction. You lost 100%.
Cause of the loss: the clock, not the call.
Every day that passed, your contract bled value (theta). You needed the move to be big AND fast...
This is why every option I touch is a year+ out so I have time for my thesis to actually play out...
Short duration is gambling.
One day you'll believe me.
