What Are Fractional Shares? Buying a Slice Instead of the Whole Share

A fractional share is when you own less than one full share of a stock or other security, as the SEC's Investor.gov defines it. If a stock trades at $1,000 per share and you have $100 to invest, fractional share investing lets you buy a tenth of a share.

Why do fractional shares exist?

Some popular stocks cost hundreds or thousands of dollars per share, which used to shut out small investors or force lopsided portfolios. Fractional shares let you put a set dollar amount to work and keep your portfolio diversified even with modest sums.

How does it work in practice?

Investor.gov explains that you can generally place orders in either dollar amounts or share amounts, and the mechanics differ between brokerage firms. Some firms execute fractional orders in real time; others aggregate orders throughout the day and fill them in batches, which can affect the price you get.

What should you check at your brokerage?

The SEC's bulletin lists the practical questions: whether your firm offers fractional shares at all, which securities are eligible (some firms limit it to certain stocks or ETFs), what order types are allowed, whether there are minimums, and whether fractional shares can be transferred to another firm if you switch brokers.

Frequently asked questions

Do fractional shares pay dividends? Yes, proportionally. A tenth of a share receives a tenth of the dividend.

Can I sell a fractional share? Generally yes, at the same proportionate price, though the same firm-specific rules about order types and timing apply. Not every brokerage offers the service, so check first.
