Fractional Shares

A single share of Berkshire Hathaway Class A stock costs over $700,000. Amazon trades above $200. Even broad market ETFs like SPY cost over $500 per share. For decades, the price of individual shares created a barrier for small investors. Fractional shares changed everything. Now you can buy $10 worth of any stock or ETF, regardless of the share price. It's one of the most important democratizing innovations in modern investing.

What Are Fractional Shares

A fractional share is exactly what it sounds like — a fraction of a full share of stock. If a stock trades at $200 and you invest $50, you own 0.25 shares. You get proportional ownership, proportional dividends, and proportional price appreciation — just like owning a full share.

Before fractional shares, if you had $100 to invest and wanted to buy a $300 stock, you were out of luck. You had to save up or buy a different, cheaper stock. Fractional shares eliminated that problem entirely.

Where to Buy Fractional Shares

Most major brokerages now offer fractional shares:

• Fidelity: Fractional shares on most stocks and ETFs. $1 minimum. Commission-free.
• Schwab (Schwab Stock Slices): Fractional shares in S&P 500 stocks. $5 minimum.
• Interactive Brokers: Fractional shares on most U.S. stocks and ETFs.
• Robinhood: Fractional shares on most stocks. $1 minimum.
• SoFi: Fractional shares with $5 minimum per trade.

Vanguard is a notable exception — as of 2025, it doesn't offer fractional shares for individual stocks (though its mutual funds have always been available with any dollar amount).

Why Fractional Shares Matter

1. Perfect Dollar-Amount Investing

Instead of thinking in shares ("I'll buy 3 shares"), you think in dollars ("I'll invest $500"). This is how most people actually budget. You have $200 per paycheck for investing? Invest exactly $200 — not 0.8 shares of this and 1.2 shares of that. Fractional shares let every dollar work immediately.

2. True Diversification with Small Amounts

With $500 and fractional shares, you can build a diversified portfolio across 10 or 20 stocks. Without fractional shares, $500 might only buy 1-2 shares of a single company. Fractional shares make diversification accessible at any investment level.

3. Automatic Reinvestment

When you receive a $15 dividend from a stock trading at $250, fractional shares let you reinvest that entire $15 — buying 0.06 shares. Without fractional shares, that $15 sits as cash, earning nothing. Over decades, the compounding benefit of reinvesting every dividend — even small ones — is significant.

4. Dollar-Cost Averaging Made Simple

Investing a fixed dollar amount at regular intervals (dollar-cost averaging) is one of the best strategies for long-term investors. Fractional shares make this seamless. You invest $300 every two weeks, and you always invest exactly $300 — no leftover cash sitting idle.

How They Work Behind the Scenes

When you place a fractional share order, your brokerage typically pools your order with others or fulfills it from their own inventory. You don't directly own a fractional share on the stock exchange — the brokerage holds the full share and records your proportional ownership. This is an important distinction.

Your fractional shares appear in your account and have all the economic rights of ownership — dividends, price changes, etc. However, you typically can't transfer fractional shares between brokerages. If you move your account, the fractional shares are usually sold and transferred as cash.

Potential Drawbacks

Limited transferability. As mentioned, fractional shares usually can't be transferred in-kind to another brokerage.

No voting rights in some cases. Depending on the brokerage, fractional share owners may not be able to vote on shareholder proposals. This matters very little for most individual investors.

Not all stocks available. Some brokerages limit fractional shares to certain stocks (e.g., S&P 500 only). Check your broker's specific offerings.

Can encourage overtrading. The ease of buying $5 of this and $10 of that can tempt investors into maintaining an unnecessarily complex portfolio. Just because you can buy 50 stocks doesn't mean you should. An index fund already gives you exposure to thousands.

The Bigger Picture

Fractional shares represent a fundamental shift in how investing works. The old model — where you needed thousands of dollars and a phone call to a broker — created barriers that kept ordinary people out of the market. Today, anyone with $10 and a smartphone can own a piece of Apple, Amazon, or the S&P 500.

This democratization is unambiguously positive. The wealth gap in America is partly a participation gap — people who invest in stocks build wealth faster than those who don't. Fractional shares remove one of the last remaining barriers to participation.
