Alpaca does not make recommendations with regard to fractional share trading, whether to use fractional shares at all, or whether to invest in any specific security. A security’s eligibility on the list of fractional shares available for trading is not an endorsement of any of the securities, nor is it intended to convey that such stocks have low risk. Fractional share transactions are executed either on a principal or riskless principal basis, and can only be bought or sold with market orders during normal market hours.

Fractional shares - invest with $1
Fractional shares allow you to invest in a portion, rather than a whole share, of a company. Our API is flexible: you can complete a fractional trade using a quantity or dollar-based amount and we’ll convert it to parts of a full share.
Test in a sandbox environment
Our sandbox environment (paper trading feature) simulates a real-time market where you can test your strategies before you invest your money. Alpaca’s paper trading feature has also become popular for schools and clubs around the world to host trading competitions.
Margin trading and short selling
Trading on margin allows you to trade and hold securities with a value up to 4X intraday and up to 2X overnight of your account equity. Alpaca currently has thousands of easy-to-borrow (ETB) securities that are available for short selling.
