Today, Wednesday May 25th, a total of 2,000 shares traded. At 0.0037 that's a big $7.40. The brokerage cost about equals the trade itself. The lenders seling those converted toxic shares won't realize a dime if they can't sell and they will not be making any more convertible loans.
For what they've made over the years it matters little if they lose out on one last loan - they knew this day would come - it's in their business plan. Wring out the last dime and and go on to the next desperate borrower.
