Yesterday, page-8

Good old tree shake. Same thing today down to only 83 though before bouncing to 90.
I have heard that the instos can see where the stops are placed by online retailers. Therefore if its in their interest they can sell down a few shares, trigger the stops, and be waiting beneath to catch the falling fruit (replacing the shares they sold earlier at a slightly higher price). From there, they can slowly accumulate more during the day at a lower price than they would have been able to. These last two trading days (among others) look like this accumulation behaviour to me. Its a good thing to see (as long as you don't have stops set!).
