15 Best Online Brokerages for First-Time Investors in 2026

3. The Power of Fractional Shares for New Investors

Fractional share investing has emerged as a game-changing feature that allows first-time investors to purchase portions of expensive stocks, making diversification possible even with limited capital. Previously, investors needed hundreds or thousands of dollars to buy a single share of companies like Amazon, Google, or Berkshire Hathaway, effectively excluding many beginners from investing in these market leaders. In 2026, fractional shares have become standard across most major brokerages, enabling investors to buy as little as $1 worth of any stock or ETF. This innovation has profound implications for portfolio construction, allowing new investors to create well-diversified portfolios across multiple sectors and asset classes regardless of their account size. The psychological benefits are equally important – fractional shares eliminate the pressure to save large amounts before investing and allow for consistent dollar-cost averaging strategies. Many brokerages now offer automated fractional share investing, where users can set up recurring investments that automatically purchase fractional shares based on dollar amounts rather than share quantities. This feature has made investing more accessible and intuitive for beginners who think in terms of dollar amounts rather than share counts.
