FundamentalStock Market2 min read

Quick Definition

A portion of a full share of stock, allowing investors to buy less than one complete share.

Key Takeaways

  • Fractional shares let investors buy any dollar amount of stock, regardless of share price.
  • They carry proportional rights to dividends, gains, and losses just like full shares.
  • Most major brokerages now support fractional trading, removing price barriers for beginners.

What Is Fractional Shares?

Fractional shares represent ownership of less than one full share of a stock or ETF. They enable investors to purchase high-priced stocks—like Berkshire Hathaway Class A at over $600,000 or Amazon—with any dollar amount, regardless of the share price. Most major brokerages (Fidelity, Schwab, Robinhood, Interactive Brokers) now offer fractional share trading, typically down to $1 or even $0.01 increments. Fractional shares carry the same proportional rights as full shares, including dividends and price appreciation. For example, owning 0.5 shares of a stock paying a $2 dividend yields $1. Fractional shares have democratized investing by removing the price barrier, making dollar-cost averaging more precise, and enabling fully invested portfolios without leftover cash. However, fractional shares may have limited transferability—some brokerages require liquidation when transferring accounts. They are also central to the operation of dividend reinvestment plans (DRIPs).

Fractional Shares Example

  • 1With $100 and Amazon trading at $180, an investor buys 0.555 fractional shares instead of waiting to afford a full share.
  • 2A DRIP automatically reinvests a $15 dividend into 0.08 fractional shares of a stock trading at $187.50.
