High-frequency trading firms (HTFs) – or algo firms on steroids –use complex algorithms and powerful computers to execute trades at lightning speeds. These firms typically try to capture the spread between the spot and futures prices, but recently they have been active in small, illiquid stocks as well.

The volumes generated by them, more often than not, attract retail investors to these stocks.
