You can't blame hedge funds when a stock drops on news like this, all the drop was in AH trading, so many sellers, no buyers.The same will persist for a few days, no one shd be buying right now.
While I also hate the HFs and hi spd traders, I blame the SEC. There is no better way to cut govt spending than to eliminate the SEC, FINRA, etc, etc, and start again with a new agency that actually does something to keep investing fair.
