Trading firms use sophisticated investing strategies and algorithms to buy and sell stocks, commodities, foreign currencies and other financial instruments.
Some trading firms, like hedge funds, trade on behalf of their clients, while proprietary trading firms, or prop trading firms, trade using their own capital. Because these firms deal in large volumes, they often become a “market maker” that buys and sells assets to other traders. By facilitating these deals, market makers provide liquidity that’s vital to the health and efficiency of financial markets.
