could someone more experienced tell me whats hapenning here.
IBM had a preliminary earning came out 2-3 days prior July 22nd, IV shot up. its expected due to unexpected event and bad news drop.
SMCI on the other hand has its earning dated for august 11 i think, but also had pre-earning release 2 days ago and IV didnt move at all. why is this?
another question, shouldnt IV immediate drop off once pre-earning is announced just like after a normal earning date? but for IBM it stays somewhat elevated even after pre-earning.
got the iv info from here https://www.alphaquery.com/stock/IBM/volatility-option-statistics/10-day/iv-call
