### Comment:
Why is ER before opening preferable?

### REPLY:
1)Pre-open trading is a lot less heavy.    
  
 2) I find that you get fucked even harder by IV crush with after-hours trading: you’ll see stocks go up up up up (assuming a strong ER) and then by morning, they’re back down.   
  
 3) Please note, I could be right for the wrong reasons, but either way, if I’m holding onto contracts through ER and they have AH reports, I make sure my expiration is at least a week or two out.
