What I saw somewhere, don't know if it's true or a rumour, was that it was a wallstreet guy offering them $5M for if he could shift the strategy. So be bought a _lot_ of shares of the very cheap pre-pivot price, paid them $5M for the pivot, sold the shares at the now 600% stock increase. Netted a tidy profit after the $5M.
They didn't trade company fundamentals, they traded the market sentiment.
