investingdog, Yahoo is wrong.
Total OI April Call Options is about 34.000+ contracts.
Puts about 5K.
The only way to chance that between yesterdays close and now is that options where exercised over-night and in that case I wonder how Yahoo pull that of because clearing happens quite late after close to give brokers and clearing instances the needed time and allow customers to call in after close.
Maybe alvaroc can confirm from his bloomberg feed.
However, IF, and only IF, they have been exercised (that would mean the 2.5 and 5$ strikes are part of it because they contain the BULK 18K contracts (and 27K must be exercised for the Yahoo numbers to be correct) then there is an explosion upcoming!
Who would pay 2.5 and 5$ for PPHM shares if you can buy them at 1.50$ on the open market?
