I don't have a clue. Been to Dave's 5-6 times in last 12 months and find it difficult to get excited about the customer experience. Just a notch above fast food really. With respect to Q4, wouldn't they have warned by now if they were going to miss? Everybody sets the bar so low, with the help of the so-called analysts, a serious miss is rare.
And as a result, a beat doesn't necessarily mean a bump, particularly if the so-called "shadow" estimates are even higher than the beat. On the other hand, in the case of DAVE, a stock that has traded tightly for the last 3 months, albeit with a positive bias, even a meet or a minor miss would not necessarily translate into a tumble since expectations are not elevated.
But basically I have no more knowledge about this company than what is available on Yahoo. If someone was planning to buy the stock I'd suggest he/she buy it before Q4 as opposed to after the press release and conference but that's only because I'm a gambler at heart always chasing risk.
