Honestly, I don't see any indication on L2 that the short suppression scheme has ended. I keep seeing a bunch of steady buying from what appears to be retail (<5000 shares). But the large block sales at pre-arranged prices all appear to be sells.
Regardless, the HFT machine is propping the SP up today for whatever reason. It could be an indication by the big short entity to the market that "this is it, no more". Hard to say based on today's activity. We need to wait a few more days.
My suspicion is, only a material event (very likely the EU partnership) will be a definite upside indicator at this point. Also, if an entity like Adage has wind of it by whatever means, they may play some funny up and down games with the SP before the PR is released in order to catch the uninformed shorts by surprise. We'll see.
