Eleven years after abandoning 1/8s and 1/16s, the SEC is considering bringing fractional prices back to the market, at least for less liquid stocks. Fractions, while considered an anachronism of old computing, used to prevent specialists and insiders from front running. Now they may be the cure we need against rapid trading. Trading in fractions bigger than decimals (cents) makes it more expensive to jump the queue in the limit-order book, perhaps making it fairer for slower small investors.
Ban calculators and let's start teaching fractions again in grade schools... Wait! Do the teachers know them?
