Fractional shares solved a specific problem — high per-share prices locking ordinary investors out of owning certain companies — and most major brokers have supported them for years now.
The Mechanics
Instead of buying a full share, you specify a dollar amount, and the broker allocates you a proportional slice of a share — Fidelity supports this from $1, Schwab from $5, and Interactive Brokers from as little as $0.01. You receive proportional dividends and voting rights (typically aggregated by the broker) on your fractional stake, same as a full shareholder, just scaled to your actual ownership percentage.
Worth knowing: Fractional shares make precise diversification achievable with a small amount — rather than concentrating your entire small starting balance into one or two full-priced shares you can afford, you can spread it across many companies in proportional dollar amounts instead.
Someone Wanting to Diversify With a Small Balance: Fractional shares make this achievable, rather than forcing concentration into whatever full shares you can afford.
Someone Wanting a Specific High-Priced Stock: Fractional shares remove the barrier of needing the full share price upfront.
Use Fractional Shares the Way
- Confirm your broker supports fractional shares before assuming a stock is unaffordable.
- Use them to diversify a small balance across multiple companies.
- Check how dividends and voting rights are handled on your specific fractional stake.
