Aries offers a range of asset classes to help you build a diversified portfolio. You can trade individual stocks, ETFs, options, and index options — all from a single platform. Each asset class carries its own risk profile; options trading involves significant risk and is not appropriate for all investors. Please review the Characteristics and Risks of Standardized Options before trading.
