High Frequency Trading while have no effect on an investor, negligible effect on a trader and sometimes an effect on an active trader (day trading). Gonna track actively? Consider sticking to high volume issues which will likely dampen the effect HFT, giving you better fills. Low volume stocks-beware! But if you are a buy hold investor, no need to worry.
they won't affect you if you stick to good large company stocks
In this climate?? Better off going to the Casino...
