They have to SMASH that open, previous topping resistance is $328.30, so an open at or over that is a green light for total takeoff...key price to watch today.
She's a total time bomb here - Friday afternoon's activity of the short squeeze, along with the gap up here and now... 15 - 30 minutes into the opening, when the SPY is at 328.75, will be an excellent opportunity to grab very cheap 8/7 puts... the 326 or 327's. There's an easy, real possibility we'll fall back to the 322 area and below betweeen now and the Wednesday close.
Just wait an watch to see if buyers come in to support the price above 328. I just think this could get ugly very quickly when profits want to get taken and there's no buyers there to support the bid price.
