SQQQ will undergo a 1:5 reverse split (also referred to as a forward split) after the close of trading on Wednesday. Thursday's open will show SQQQ priced 5X higher and all strike prices on the underlying options will also be adjusted 5X higher. What will be the same is the value of any option positions from Wednesday's close to Thursday's pre-Open. No action is required for option holders. It will certainly mess up the active option trade table so I will to save a copy here since the post-split table will have to be adjusted.
