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.
Investments in securities involve the risk of losses and past performance does not guarantee future results.
There is no guarantee that any investment strategy will achieve its objectives.
Please note that diversification does not assure a profit, or protect against loss.
There is always the potential of losing money when you invest in securities, or other financial products.
Investors should consider their investment objectives and risks carefully before investing.
