Ann: Ceasing to be a substantial holder, page-16

Pretty embarrassing that the cornerstone investor is now out after being patient for a very long time. I guess opportunity cost and disappointment. Red flag nonetheless

I wonder how long Jefferies will stay onboard

as for buying and selling, sometimes instos buy to keep the price up or to try and initiate a mini pump so they can sell into the higher price. Pretty standard stuff. Best to look into the broker data on a day by day basis to get a better picture of what they were doing if it's interesting to you. Getting out at break even is better than getting out at a loss
