At the current prices that would be 100 contracts that says by end of next week the SP will hit $650. BUT, for that to turn into $1M - the SP needs to hit $750 !!
The IV for 1/31 options is absolutely insane at over 110%.
It's understandable why, though. You have people who are sure that this is an epic bubble (wherein the ER will "pop it"), and you have people thinking that this ER will confirm forecasts of sustained profitability, early Model Y production, or even an unexpected early S&P criteria qualification - wherein this ER will give a highly volatile stock that keeps trying to surge even higher the footing it needs to do so.
I normally don't do "lotto tickets", but I did get a few for this ER, and will probably pick up a few more. A tiny position, though. $750-800 21 Feb '20 call spreads (by my standards, those are lotto tickets ). Over the past day or two they've been averaging around $200 each (max theoretical gain = 24x/$4800), about the same cost as $900 21 Feb '20 calls, meaning at expiry the stock would have to be $950 or more to get a better return on the $900s, if held to expiry. Picked up 3 yesterday, would like to be up to 10 or so by the ER, but it depends on how prices shift.
