Do large market players using HFT make it unsafe for individual investors to be in the stock market?
Obviously there are good answers about the alternatives to the stock market in the referenced question.  HFT has been debated heavily over the past couple of years, and the Flash crash of May 6, 2010, has spurred regulators to rein in heavy automated trading. HFT takes advantage of churn and split second reactions to changing market trends, news and rumors. It is not wise for individual investors to fight the big boys in these games and you will likely lose money in day trading as a result. HFT's defender's may be right when they claim that it makes the market more liquid for you to get the listed price for a security, but the article points out that their actions more closely resemble the currently illegal practice of front-running than a negotiated trade where both parties feel that they've received a fair value. There are many factors including supply and demand which affect stock prices more than volume does. While market makers are generating the majority of volume with their HFT practices, volume is merely the number of shares bought and sold in a day. Volume shows how many shares people are interested in trading, not the actual underlying value of the security and its long term prospects. Extra volume doesn't affect most long term investments, so your long term investments aren't in any extra danger due to HFT. That said, the stock market is a risky place  whether panicked people or poorly written programs are trading out of control. Most people are better off investing rather than merely trading. Long term investors don't need to get the absolute lowest price or the highest sell. They move into and out of positions based on overall value and long term prospects. They're diversified so bad apples like Enron, etc. won't destroy their portfolio. Investors long term view allows them to ignore the effects of churn, while working like the tortoise to win the race while the hare eventually gets swallowed by a bad bet. There are a lot of worrying and stressful uncertainties in the global economy. If it's a question of wisdom, focus on sound investments and work politically (as a citizen and shareholder) to fix problems you see in the system.
