Fears that high-speed traders have been rigging the U.S. stock market went mainstream last week thanks to allegations in a book by financial author Michael Lewis, but there may be a more serious threat to investors: the increasing amount of trading that happens outside of exchanges. And this problem could cost investors far more money than any shenanigans related to high frequency trading. When the average investor, or even a big portfolio manager, tries to buy or sell shares now, the trade is often matched up with another order by a dealer in a so-called "dark pool," or another alternative to exchanges. Those whose trade never makes it to an exchange can benefit as the broker avoids paying an exchange trading fee, taking cost out of the process.
