As to how it would be done SF....I'm constantly going back to this Business Insider article on the so called "Richard Wyckoff Method" for accumulating stocks.

It takes a while for a pro to accumulate a position in advance of a big move – buying too many shares at once would cause the price to rise too quickly

AP

"The preparation of an important move in the market takes a considerable time. A large operator or investor acting singly cannot often, in a single day's session, buy 25,000 to 100,000 shares of stock without putting the price up too much. Instead, he takes days, weeks or months in which to accumulate his line in one or many stocks."

As for 2013.....I don't know how many shares were issued back then...wait...I'll check. About 75 million.....okay. So someone looking to "shake the tree" could borrow a bunch of shares..."raid the stock" to use the parlance employed in the above article....and after borrowing then selling a few hundred thousand and dumping them....now you have the price moving down in combination with the bad trial news....How is Joe Retail going to react? Sh*t, the effer is gonna go to zero...I better get out while I still can....hell 10 or 20 cents is still better than $0...So not only does the "pro" make a killing buying back the shares he borrowed and sold at much higher prices....he could also accumulate boat loads more perhaps.
