Fractional shares trading in the US stock market
1. What is a fractional shares order?
A fractional shares order is a type of US stock order that allows investors to buy or sell fractions of a stock in decimals, instead of requiring whole shares. Fractional trading allows investors to buy and sell stocks at a lower total order cost than the minimum cost of buying or selling 1 whole share.
