Best Brokerage Accounts for Fractional Share Investing

Analysis by Elijah Finn, Registered Investment Advisor (RIA) & Principal Analyst, Core Capital Report.

The Democratization of Investing

For young investors, the price of a single share in leading companies like Tesla, Amazon, or Berkshire Hathaway can often be prohibitively high, creating a major barrier to entry and diversification. Fractional Share Investing solves this problem by allowing investors to buy tiny pieces of expensive stocks or Exchange-Traded Funds (ETFs) for as little as $1.

This feature is arguably the most significant tool for democratizing investing in the last decade. It enables investors to build a diversified portfolio based on dollar amounts, not on share prices, making it the ideal starting point for investors in their 20s and 30s.

As an RIA, I emphasize that consistency and diversification are key. Fractional shares allow small, regular investments to immediately achieve broad diversification, reducing single-stock risk.

The Benefits of Fractional Share Investing

The ability to buy partial shares provides several strategic advantages, especially for investors focused on dollar-cost averaging (DCA).

  • 1. Immediate Diversification: Instead of putting all $100 into one stock, you can spread that $100 across 10 different stocks or ETFs, significantly lowering portfolio volatility.
  • 2. Access to Expensive Stocks: You are no longer priced out of high-value companies. A $500 investment can now buy fractions of Alphabet (Google), Apple, and Amazon.
  • 3. Dollar-Cost Averaging (DCA): Fractional shares facilitate pure DCA. You can commit a fixed amount (e.g., $50 every week) to an investment, regardless of the stock’s price, ensuring you buy more shares when prices are low.

Top Brokerage Accounts for Fractional Share Investing

Choosing a brokerage for fractional shares depends on low minimums, low fees, and the breadth of the assets available for fractional purchase.

Investment Strategy: Building a Fractional Portfolio

Fractional share capabilities should inform the structure of your portfolio, moving you away from individual stock picking toward broader market exposure.

1. Prioritize ETFs Over Single Stocks

For beginners, using fractional shares to purchase diverse ETFs (e.g., a Total Stock Market ETF like VTI or a S&P 500 ETF like VOO) is far more effective than buying fractional shares of single companies. This ensures built-in diversification.

2. Embrace Dollar-Cost Averaging

Set up automatic, recurring transfers from your bank account to your brokerage. Then, set up automatic, recurring investments into your chosen fractional assets. Automation removes the emotional element from investing and maximizes the power of compounding.

3. Reinvest Dividends

Ensure your fractional account is set to automatically reinvest any dividends earned back into the underlying fractional shares. This utilizes tax-free compounding and grows your holdings without requiring fresh capital.

Starting Small, Thinking Big

The barriers to entry for serious investing have never been lower. Fractional share investing is the perfect tool for young professionals, allowing them to participate in the entire market with limited capital. By prioritizing zero-commission platforms like Fidelity or M1 Finance and maintaining disciplined, automatic investments, you can build a robust, diversified portfolio designed for long-term wealth accumulation.

Use the $0 minimum feature to start investing your next paycheck today, regardless of how small the amount is.
