I thought the same as BRICK at first, until I realized that the preferred conversion could only apply to the old shares. So instead of 2,500,000 preferreds that could be converted into 1000x old shares (= 2,500,000,000 old shares), they would now have to convert into just 10x the new shares (= 25,000,000 new shares). That's still a lot of shares but wouldn't explain the 400M volume Friday. Just my humble opinion.
