Fractional Shares: Small Yes, But Useful Too
E*TRADE from Morgan Stanley
A fractional share represents ownership of less than one whole share of a stock or exchange traded fund. For instance, if a stock is trading at $1,000 per share and an investor decides to invest $100, they would own 0.10 (1/10) of a share of that stock. This concept is gaining traction as more brokerages offer dollar-based investing options, allowing investors to purchase a specific dollar amount of a stock or ETF, which results in fractional shares if the amount does not equate to a whole share.
Fractional shares have gradually spread across the investment landscape over recent years, and many Investors have come to recognize the useful role they can play.
Investing in High-Priced Stocks
They allow an investment in high-priced stocks without needing to pay the full share price, making it easier to access popular, high-performing stocks.
In today’s market, many popular growth stocks trade for hundreds or thousands per share—at this writing 95 stocks in the S&P 500 are $300 or more—so fractional shares present an opportunity for an investor to own these stocks without the need to buy a full share. Investors can trade in specific fractions, such as 0.25 or 0.10 shares, or in a specific dollar amount. By enabling investments in smaller increments, fractional shares have democratized access to the stock market, allowing a broader range of investors to participate in the financial markets.
Diversification for Small Portfolios
Because smaller dollar investments enable access to high-priced stocks, they also allow for effective portfolio diversification, letting investors spread their capital across multiple holdings to help mitigate risk and enhance potential returns.
This is particularly useful for ETF investors. Investments in exchange traded funds occur at a real-time market price per share, on stock exchanges, of course. Without fractional share access, a small portfolio is difficult to manage and maintain at a target asset allocation. Consider an investor who wishes to build a $1,000 portfolio with 70% stocks and 30% in bonds. If the stock ETF is $150 per share the investor would invest only $600 with 4 shares, and would have 75% in stocks with 5 shares. With fractional shares, investing and managing allocated portfolios is simple and efficient.
Automated Recurring Investment
Many investors use automated systems to make regular periodic additions to a portfolio in set dollar amounts from scheduled electronic transfers. If these transfers are invested in the same allocation, the portfolio benefits from dollar-cost averaging, smoothing out the effects of market volatility over time.
Dividend Reinvestment
And finally, fractional shares are necessary for efficient dividend reinvestment. Consider that a cash dividend payment might be far less than the price of a share of that stock, so with fractional shares, the dividend can be fully invested in the stock or ETF.
Limitations and Considerations?
Despite their advantages, there are important limitations and considerations associated with fractional shares. Not all brokerages support fractional share trading, and the availability of supported securities can vary1. Additionally, trading constraints may apply, as some firms limit fractional share trading to regular trading hours. Another consideration is that fractional shares may not carry the same voting rights as full shares, as some arrangements do not pass through proxy voting rights due to how the broker holds or records the position. Furthermore, transferring accounts can be complicated, as a receiving broker might not accept fractional positions, potentially requiring the liquidation of the fractional portion. Lastly, fractional investing can increase the complexity of tax lot and recordkeeping, as it may result in a higher number of "lots" and complicate cost basis tracking.
Regardless of the twists above, fractional shares give investors a useful approach to stocks and portfolios in four important ways—access to high-priced stocks and ETFs with a lower financial barrier to entry, smaller increments enabling diversification and automated portfolio investing strategies, and efficient dividend reinvestment in stocks and exchange-traded funds.
As the investment landscape continues to evolve, fractional shares represent another significant step towards democratizing access to the financial markets, empowering a new generation of investors to participate in the wealth-building potential of the stock market.
