Investing once commonly meant working directly with a broker or using specialized financial services. Today, online platforms and smartphone apps give ordinary investors access to market information, research tools, automated investing, fractional shares, and the ability to place trades from almost anywhere.
This page highlights the technology and tools that make investing more accessible. It is not a recommendation to buy or sell any investment.
