All stocks have the high frequency platforms that these hedge funds use to trade by milli seconds. It is what supports the most of the market volumes on the indicies. It actually funny if you watch on a down day these platforms are not around to support the market on up days they are trading so fast. Example the May flash crash happened and the high frequency trading was no where to be found. They continue to allow these types of super computers to do the work they will have a riot on their hands. The flash May crash wasn't the last time either considering they installed circuit breakers to halt trading of stocks if they fell 10.00% it triggered it to halt for 5 mins. Funny the SEC installed these measures yet still stocks crashed after wards and the circuit breakers never worked and bear raids were done on many stocks that I have seen. Citigroup was attacked a month later, AVNR was bear raided right before an FDA approval, TGB was crashed on both sides of the exchanges but it was never halted for impending approval of a mine, nor did it trip circuit breakers. They should never allow such things to happen I would not be surprised if a bear raid goes on this week whether it be Ford or GM because both are on high voltage of the impending GM IPO and all the press GM is getting. I would not be surprised either if investors put in a stink bid on the just in case side on either stock hoping for one of these bear raids. Though highly suspicious if this happened they would probably halt trading because of the massive volume Ford generates. Shorts are bad enough high frequency trading is deadlier. SEC needs to put a lid on high frequency trading as it will again crash the market because nobody has control of it and would not be surprised either if it was done by insider trading or greed for profit.
