Do large market players using HFT make it unsafe for individual investors to be in the stock market?
There's a lot of hype about HFT. It involves computers doing things that people don't really understand and making a bunch of rich guys a bunch of money, and there was a crisis and so we hate rich wall street guys this year, and so it's a hot-button issue. Meh. There's some reason for concern about the safety of the markets, but I think there's also a lot more of people trying to sell you a newspaper. Remember that while HFT may mean there are a lot of trades, the buying and the selling add up to the same thing. Meanwhile, people who buy stock to hold on to it for significant periods of time will still affect the quantity of stock out there on the market, applying pressure to the price, buying and selling at the prices that they think the security is worth.  As a result, it's unlikely that high-frequency trading moves the stock price very far from the price that the rest of the market would determine for very long; if it did, the lower-frequency traders could take advantage of it, buying if it's too low and selling if it's too high. How long do you plan to hold a stock? If you're trying to do day-trading, you might have some trouble; these people are competing with you to do the same thing, and have significant resources at their disposal. If you're holding onto your stock for years on end (like you probably should be doing with most stock) then a trivial premium or discount on the price probably isn't going to be a big deal for you.
