High-Frequency Trading
Definition
Algorithmic trading that uses powerful computers to execute large numbers of orders at extremely fast speeds, often measured in microseconds.
Explanation
HFT firms account for roughly 50% of US equity volume. They profit from tiny price discrepancies, market making (earning the bid-ask spread), and latency arbitrage (exploiting speed advantages between exchanges). HFT has compressed bid-ask spreads and improved market liquidity but raised concerns about fairness, flash crashes, and the arms race for speed. The 2010 Flash Crash (Dow dropped 1,000 points in minutes) highlighted the risks of algorithmic trading in stressed markets.
