Hft market makers if colluding would not need to short fb to drop the price. They would just drop all or most of the ask bids would normally be met by whatever people sold... even if it was equal to the number of shares bought in that minute the price would drop.
They can easily pick the price this way and even use an algorithm to do it automatically based on whatever mathematical criteria.
Btw most of the mainstream trading info you read is provided by big money.... the people collecting your trading fees.
Volatility Option "speculators" are the only people who significantly cut into their profits because of the huge percent returns they can make. So they will cheat the options market any way they can.
