An unknown trader has made nearly $200 million (and counting) in the last week playing tech earnings. This assumed single entity opened ITM short call positions on both $MSFT and $GOOG in the days leading up to their earnings. They shorted the MSFT 445c 1/30 calls over the course of 2 days before $MSFT dropped 10% post earnings, realizing nearly $155 million on the trade. They placed a similar trade with $GOOG, shorting well ITM calls that have since gone far out of the money. Another $60 million has been realized today. And still they appear to have another position, tthis time in $AMZN: shorting (at the time ITM) 227.5 weeklies from on Monday, Tuesday, and Wednesday of this week. This position can potentially bring them another $70 million in profit. $AMZN reports earnings tonight!
