The rules changed recently (a few weeks ago) requiring MM's to post the actual net (retail + MM) shares available for sale at the best bid and ask, instead of hiding the actual data. Frankly it looks to me like another MM raid, like the last two to try and collect cheap shares by scaring retail into selling think the sky is falling.
Now that the rules have changed, MM's can use it to try and show support or resistance with huge numbers of fake phantom shares (but they pull quotes if challenged). I have no doubt if someone slammed the ask with a 50,000 share buy at market order that the ask would rise quickly!!!
Alternatively it could be an unskilled TTEG contractor with some shares trying to convert to cash, but I doubt it. This looks more like a timed MM bear raid to me.
I do not see this as a Washington Debt crisis panic sale, as I do not see it in my other stocks, all the way from China RMs to NVS shares, or AA shares that I hold.
It could also be that somebody knows good news is pending, and they want cheap shares today!!!!!
Markets have been climbing all morning since the gap down at open, and NASDAQ is already almost green, so what ever is going on, I am not buying it (In other words I am not selling, I am holding all my shares).
