I have explained that filing in the past and your conjecture is just that. The company would know if Sentient was selling and they say nothing has changed. I know everyone is looking for answers but if it was sentient I think the company would know so I don't think the answer lies in this direction.
It would not surpise me to see the computers turn around in the other direction and take this back up about as fast as it came down, since making money has to be the driving motive and my guess is they about wrung out all they can get so now the money is likely to the upside. Things that make no sense can't last and will certainly go where they should based on the truth and facts, the question is how much damage will they do and who dumps because of fear and gets screwed and who makes money as balance to the force is restored.
I still maintain most action today was a forced sell but certainly some shorts would have got involved along with the computers and some fear selling from retail guys and certainly I understand fear but that doesn't mean I act on it as this ususally produces a poor outcome.
