I have no idea tbh.  I just look for high IV plays to try and sell iron butterflies then close them at open. 
  
 In my opinion markets are irrational in the short term so it's a crap shoot as to why stocks move up or down immediately after earnings.  I believe it usually takes a few days to a few weeks for a real trend to form on a stock post earnings.
