The SEC recently caught two fraudsters by switching to a sophisticated, technology-based strategy that allowed them to focus on the traders themselves rather than following the movement of the stocks. Known as parallel trading, the tactic is one of several tech-focused methods the SEC is deploying to keep pace with high-speed traders and fast-growing markets.
