A disclaimer - I think this is a very low possibility of happening, but something to keep any eye on.
Super bullish so far today, really started yesterday with that close. I'll have level2 up today and post anything interesting here in this main post. I'm already starting to see some large 'support' levels move up with the price action.
That said, the OI for the 30C tomorrow is \~5200. And it currently is at a delta of \~.12... think of that as going 'ITM' probability and what hedges are usually built off of (gross over simplification). If GRPN hits $28, that means an additional \~115,000 shares will need to be bought, if it hits $29 it will be an additional \~80,000. That is just from this week's expiration. I would be shocked if that wasn't defended with every trick in the book - maybe even some that aren't in the book. I haven't closed any positions yet and probably won't today, but I'll update this if I do.
edit: 11:06 EST - holy fucking hulk candle there.
edit: 11:30 EST - it's hanging in there pretty good, some profit taking on the Aug 30C but the July 30C has really increased in volume, over 1600 already. The delta has doubled already.
edit: 12:00 EST - really bullish again, very little (if any) downwards pressure. If this gets close to $30 today, I would expect the volume to really kick in. This is still pretty low volume today so far.
edit: 1:30 EST - that was a pretty low volume drop there, I think some of it was short, but not a whole lot. The bid/ask spread has really tightened up which is due to an increase in volume. Still looks very bullish right now, haven't closed anything. Getting this close to $29 today is a massive win. I would still, as always, expect some fuckery with the price, it's going to get hit I'm guessing, maybe even halted.
edit: 1:52 EST - every single dip keeps getting instantly bought up. Delta has dropped a bit on the 30C, but I think those are actually in play now. I think this needs to absolutely close over $28 for there to be a chance or it needs some actual AH volume.
edit: 3:00 EST - pretty bullish all day long. the only time we saw a bit of downward pressure was when the upwards pressure took a breather. I think a gamma squeeze is absolutely in play for tomorrow, I'd still be against it but it's a whole lot more likely now than it was going into the day. Keep in mind, the 30C has another \~2400 today in volume... some of which are contracts closing out, so we'll see the numbers in the morning.
**EDIT: Market Close - really fucking bullish... all day. I think those 30C are absolutely in play tomorrow. Buckle up.** **I didn't close anything today, in fact opened a few of those 1DTE 30C.**
