Fractional Shares: How Small Slices of Familiar Companies Teach Kids the Stock Market

Ask a seven-year-old what Disney is, and you’ll hear about movies. Ask what it means to own a piece of Disney, and you’ll probably get a blank look. For most of the stock market’s history, closing that gap took real money, because shares were bought whole, and as Fidelity’s guide to fractional shares points out, some companies’ stock trades for hundreds or even thousands of dollars a share. Fractional shares change the math. They let you buy part of a share by the dollar, so $10 of birthday money can buy a real stake in the company behind a child’s favorite movie, snack, or game.

That small stake can do a lot of teaching. It rises and falls with the company, collects its share of the dividends, and gives a child a reason to care what the business does next. This guide explains how fractional shares work, how to trace a favorite brand to a company you can actually buy, which of your child’s accounts can hold a slice, why the slice should stay small, what it can teach at each age, and the fine print to know before you start. It’s part of The GoodNest Guide to Investment Strategies & Portfolio Allocation, which covers how to build the rest of a child’s portfolio.

What a fractional share is

The SEC’s investor bulletin on fractional share investing defines a fractional share simply: owning less than one full share of a stock or other security. You can usually place the order either as a dollar amount or as part of a share. In the SEC’s example, if a stock trades at $1,000 a share and you have $100 to invest, you can buy 0.1 of a share.

The idea isn’t new. FINRA’s guide to investing in fractional shares notes that dividend reinvestment plans have long created fractional shares, because a dividend almost never divides evenly into the share price. What’s new is that many brokerages now let you buy slices on purpose, and their programs differ. Two of the largest show the range:

• Fidelity. You can buy slices of stocks and exchange-traded funds (ETFs) listed on the NYSE or Nasdaq for as little as $1, using market or limit orders that are good only for that day. Orders can be entered at any time but fill only during regular market hours, about 9:30 a.m. to 4:00 p.m. Eastern time.
• Schwab. Schwab Stock Slices lets you buy any stock in the S&P 500 for as little as $5 a slice, and up to 30 companies in a single order. Only S&P 500 companies are available, and Schwab lists custodial accounts among the eligible account types.

A slice behaves like the whole share it came from, only smaller. If the stock rises 10%, the slice rises 10%. If the company pays a dividend, you get your proportional share: the SEC’s example is that owning 0.75 of a share when the company pays $10 a share brings you $7.50. Stock splits work the same way.

Here’s what that looks like with a child’s money. Say your daughter has $20 from a birthday card and wants to own part of a company whose shares cost $400. A whole share is out of reach, but $20 buys 0.05 of a share. If the price climbs to $440, her slice is worth $22. If it drops to $360, it’s worth $18. The amounts are small, but the experience of watching her own money move with a real company is the same one a much larger portfolio provides.

Why familiar companies make good teachers

Children know dozens of companies by their products long before they know what a stock is. A slice of one of those companies gives the stock market a face: the cereal at breakfast, the game on the tablet, the sneakers by the door. Once your child owns a piece of the business, news that it launched a new product, raised prices, or had a rough quarter becomes their news, and the market stops being something that happens only on a screen.

The approach has a famous champion with a famous caveat. Peter Lynch, who ran Fidelity’s Magellan Fund from 1977 to 1990, made “invest in what you know” one of the best-known ideas in investing, but he never meant that liking a product was reason enough to buy the stock. In a 1994 speech recounted by GuruFocus, Lynch said the most important thing in the stock market is knowing what you own, and he proposed a simple test: you should be able to explain your reason for owning any stock to a 10-year-old in about 10 minutes. Decades later, he complained that the popular version of his advice leaves out the research, according to a Benzinga report on his comments to MarketWatch, and he cautioned that even professionals find stock picking hard.

That test is made for kids. Before your child buys a slice, ask them to explain, in their own words, what the company sells, how it makes money, and why they think it will do well. Write the answer down, date it, and reread it a year later. The note teaches more than the price chart does, because it shows your child whether their reasoning held up, not just whether the stock went up.

Find the company behind the brand

Most brands kids know aren’t companies you can buy directly. They belong to a parent company, often with a different name, and some belong to companies that don’t sell shares to the public at all. Tracing a favorite product to its owner makes a good first research project, and the answers often surprise kids.

Examples of how brands trace to companies, not recommendations. Tickers are for U.S. listings. Companies buy and sell brands, so confirm ownership in the company’s latest annual report before your child buys.

LEGO is the useful exception. The LEGO Group is owned by KIRKBI, the Kirk Kristiansen family’s holding company, and the LEGO Foundation, according to LEGO’s ownership page, so there are no LEGO shares to buy on any exchange. Explaining why some companies sell shares to the public and others stay private is a lesson in itself.

To find out who owns a brand, start with the company’s annual report. Public companies file them with the SEC, and anyone can read them free through the SEC’s EDGAR company search. The business section near the front of the annual report, known as Form 10-K, usually describes the company’s main products and brands and how it makes money, which is good reading practice for a middle schooler.

Then check that your brokerage’s program covers the stock. Fidelity’s covers stocks listed on the NYSE or Nasdaq, while Schwab’s covers only S&P 500 companies. Some favorite brands belong to companies whose shares trade only outside the United States or over the counter, which neither program offers.

Where slices fit in your child’s accounts

Not every account can hold a slice of an individual company. Here’s how the common accounts for children compare:

Brokerages set their own rules, so check your firm’s list of eligible accounts and securities before you buy.

A custodial account is the natural home for a learning slice. The money belongs to your child, but you choose the investments until your child reaches the age set by your state’s law. UTMA vs. UGMA explains the two kinds of custodial accounts, and Custodial Brokerage Accounts vs. Parent-Owned Taxable Accounts weighs a custodial account against keeping the money in your own name.

For teens, the question is how much control to hand over. A Fidelity Youth Account belongs to your teen, who places the trades, including fractional shares starting at $1, while you can see the account but can’t trade in it, according to Fidelity’s Youth Account FAQs. Teen Brokerage Accounts vs. Custodial Accounts compares that setup with joint and custodial options.

529 plans and Trump Accounts are a different story. A 529 plan offers a menu of portfolios chosen by the plan rather than individual stocks, as The Complete Guide to 529 College Savings Plans explains. And under IRS Notice 2025-68, until January 1 of the year your child turns 18, a Trump Account can hold only mutual funds or ETFs that track an index of mostly U.S. companies and charge no more than 0.1% a year. That’s no loss for teaching purposes. The index funds in those accounts already own small pieces of many of the companies your child knows, which is worth pointing out the next time you look at a statement together. The 530A Trump Account Explained has the details.

Keep the learning slice small

The biggest risk in a child’s first stock isn’t the fraction. It’s the stock. A slice gains or loses the same percentage as a whole share, and a single company can fall much further, and stay down much longer, than the market as a whole.

Finance professor Hendrik Bessembinder showed just how lopsided the results of individual stocks are. Studying nearly 26,000 U.S. stocks from 1926 to 2016, he found that 58% failed to beat one-month Treasury bills over their lifetimes and another 38% beat them by only moderate amounts, according to a summary from Arizona State University’s W. P. Carey School of Business. Just 1,092 companies, about 4.3% of the total, accounted for all $35 trillion of wealth that stocks created beyond what Treasury bills would have earned.

• Trailed Treasury bills (58%)
• Beat them by moderate amounts (38%)
• Created all the net wealth (4%)

Each square stands for about 1% of the nearly 26,000 U.S. stocks in Hendrik Bessembinder’s study, from 1926 to 2016. Lifetime returns include reinvested dividends and are compared with one-month Treasury bills over the same years. Shares are rounded as Arizona State University reported them, so the squares show 58, 38, and 4; the big winners were 1,092 companies, about 4.3% of the total. Past results don’t predict future ones.

See the numbers

Lifetime results of U.S. stocks, 1926 to 2016

Group	Share of stocks
Trailed one-month Treasury bills over their lifetimes	58%
Beat Treasury bills by moderate amounts	38%
Created all the net wealth above Treasury bills1,092 companies, about 4.3%	4%

The market as a whole did well because a small number of huge winners pulled the average up. In his paper, Bessembinder concluded that this lopsided pattern helps explain why poorly diversified strategies most often trail market averages. A child who owns one or two familiar companies is running exactly that kind of strategy. An index fund, by contrast, owns the eventual big winners automatically, whoever they turn out to be.

That’s why Index Funds vs. Stock Picking for Minors recommends a broad, low-cost index fund as the core of a child’s savings, with individual stocks as a lesson rather than the plan. The SEC’s guide to asset allocation and diversification makes the underlying point: spreading money among different investments can reduce risk and help limit losses. The GoodNest Guide to Investment Strategies & Portfolio Allocation shows how that core fits with bonds and cash as your child grows.

How small is small?

There’s no official limit, but a few guardrails keep the experiment in proportion:

• Set a cap. This guide’s rule of thumb is to keep the learning slice to about 5% to 10% of the account, or to a fixed dollar amount. In a $10,000 custodial account, a 5% slice is $500, enough to own pieces of several companies.
• Fund it with new money. Use part of a birthday gift or a teen’s own earnings rather than selling the index fund. In a custodial account, selling shares at a gain creates taxable income for your child.
• Trim a runaway winner. If one pick grows far past the cap, consider selling part of it. FINRA notes that fractional trading lets you sell a precise dollar amount, so you can trim a position back to its target exactly.
• Keep score against the index. Once a year, compare the picks with what the same money would have earned in an S&P 500 index fund. Some years the picks will win. The real question is whether your child could count on winning for 18 years in a row.

What a slice can teach

Once your child owns a slice, ordinary events become lessons. These are the ones that come up most often, and a slice makes each of them concrete:

• Ownership. A share is a small piece of a company, and a slice is a piece of that piece. Even 0.05 of a share means your child owns a sliver of every store, factory, and brand the company has, and a claim on part of its future profits.
• Prices move every day. A stock’s price changes throughout the trading day. Checking once a month, not once an hour, teaches that daily wiggles matter less than how a business does over years.
• Orders and timing. A market order buys at the best price available, while a limit order sets the most you’re willing to pay. Fractional orders add a twist. Some firms accept only market orders for slices, and some collect fractional orders during the day and fill them together, which can affect the price you get, according to the SEC. When Schwab introduced Stock Slices in 2020, it said slices would trade in real time using market orders. Fidelity marks any order with a fractional part “not held,” which gives it time and price discretion in filling the order.
• Dividends. When a company pays out part of its profits, your child gets a proportional cut. With dividend reinvestment turned on, those cents buy a little more of the slice, a first look at the compounding that How Does Compound Interest Actually Work for Minors? explains.
• Earnings and news. Public companies report results every quarter. Reading the headline numbers together, or listening to the first few minutes of an earnings call, shows how a business gets judged.
• Volatility and patience. Every stock has bad stretches. Watching a $20 slice drop to $15 and deciding what to do is a far cheaper way to learn about risk than doing it with $20,000.
• Beating the market is rare. The yearly comparison with the index fund teaches the hardest lesson in investing, and Bessembinder’s numbers explain why.
• Taxes. In a custodial account, dividends and gains are your child’s income. In 2026, the first $1,350 of a child’s investment income is tax-free, the next $1,350 is taxed at the child’s rate, and income above $2,700 can be taxed at the parents’ rate, under Revenue Procedure 2025-32. A learning slice rarely comes close, but selling a winner is a good moment to show a teen what a capital gain is. Navigating the 2026 Kiddie Tax Thresholds has the rules.

Activities by age

What a slice can teach depends on your child’s age. Here’s a progression that grows with them, following the stages in The Age-By-Age Playbook to Financial Literacy:

Each stage has its own guide with more ideas, starting with The Early Years (Ages 3-5), Grade School (Ages 6-10), Middle School (Ages 11-14), and High School (Ages 15-18). Two habits work at every age. Keep a simple investing journal with the company, the date, the price, the amount, and your child’s reason for buying. And make the yearly review a ritual, with the journal, the statement, and the comparison with the index fund on the table together.

For teens earning their own money, a parent match can turn the lesson into a habit, and The “Match” Program explains how to offer one. Kids who want their picks to reflect what they care about can start with ESG Investing for the Next Generation.

The fine print

Fractional shares come with limits that whole shares don’t. The SEC’s bulletin, FINRA’s guide, and Fidelity’s FAQ flag the main ones:

• You usually can’t move them. You generally can’t transfer fractional shares to another brokerage firm, so moving the account may mean selling them first, the SEC says. Fidelity says its fractional shares must be sold before any transfer out. In a custodial account, that sale can create taxable gains for your child, so open the account somewhere you expect to stay.
• You may not get a vote. Whether you can vote on shareholder matters depends on your firm’s program, and some firms don’t allow it for fractional shares at all. Fidelity doesn’t allow proxy voting on the fractional part of a position.
• Order types and hours can be limited. Some firms accept only market orders for fractional shares, limit after-hours trading, or take fractional orders only through a mobile app, according to the SEC.
• You may get slightly more or less than you asked for. Fidelity rounds dollar-based orders down to the nearest 0.001 share, so the value you receive can be a little higher or lower than the amount you entered.
• Not every stock qualifies. Firms may limit which stocks and ETFs you can buy in slices. Schwab’s program, for example, covers only S&P 500 companies.
• A buyer isn’t guaranteed. The SEC notes that some firms don’t guarantee you’ll be able to sell fractional shares even when whole shares trade easily, and Fidelity warns that a market may not be available for fractional shares of some securities.
• Small fees can apply. Commission-free trading is common, but ask about fractional fees. Fidelity, for example, charges an assessment fee on every sell order of $0.01 to $0.03 per $1,000 sold.

None of this is a reason to avoid slices. It’s a reason to keep the learning slice small, plan to hold it for years, and pick a brokerage you’ll be happy to keep. And remember whose money it is. Investments in a custodial account belong to your child for good, and your child takes control at the age your state sets, so a slice bought at 8 may be your child’s to keep or sell at 18 or 21, as What Happens at the Age of Majority? explains.

Turning family gifts into slices

Relatives often love this idea, because a slice of a company is a gift a child can follow for years. A grandparent’s $25 birthday gift won’t buy a whole share of many well-known companies, but it can be split: $10 for a slice of the company your child has been researching and $15 for the index fund at the core. Fractional shares make that kind of split easy, because you can invest exact dollar amounts instead of rounding down to whole shares.

GoodNest can collect those gifts, often alongside a small keepsake. Guests give from your child’s GoodNest page and send the money straight to you by Zelle, Venmo, or PayPal. GoodNest never holds or invests it, so you decide where each gift goes, whether that’s the index fund at the core or the learning slice for the company your child picked. A few ways to make the gift feel real:

• Connect the slice to the giver. Note in your child’s investing journal which company each gift bought and who gave it.
• Print the moment. If you buy through Schwab Stock Slices in a custodial account, Schwab lets you print and personalize an announcement of the purchase, which pairs well with a thank-you note.
• Report back. Once a year, tell the giver how their slice is doing, in good years and bad. Thank You Notes and Portfolio Updates has ideas for what to send.

Gifts like these are far below the federal gift tax annual exclusion, which is $19,000 per giver, per recipient, in 2026 under Revenue Procedure 2025-32, so they won’t require a gift tax return. The Impact of the 2026 Gift Tax Exclusion covers larger gifts, and The GoodNest Guide to Asking for Investments Instead of Toys has ideas for starting the conversation with family.

Mistakes to avoid

• Letting the slice become the strategy. A few familiar companies are a lesson, not a diversified portfolio. Keep the index fund at the core.
• Buying the brand without the business. Loving a product isn’t a reason to own the company. Use Lynch’s test and write the reason down first.
• Checking prices every day. Daily price checks turn a long-term lesson into a game of chance. Monthly is plenty for young kids, and quarterly works for teens.
• Chasing what’s popular. A stock everyone is talking about isn’t automatically a good business, and the hype is a lesson in itself.
• Selling the core to fund the picks. In a custodial account, selling at a gain creates taxable income for your child. Use new money instead.
• Forgetting about transfers. Switching brokerages usually forces you to sell fractional shares, so choose a firm you plan to keep.
• Picking for your child. The point is for your child to choose, within your guardrails. A pick they researched themselves teaches far more than one you made for them.

The bottom line

A fractional share may be the cheapest teaching tool in investing. For a few dollars, it turns a favorite brand into a stake in a real business, with real price swings, real dividends, and a real reason to read the news. The trick is keeping it in proportion: a small, researched learning slice next to a broad index fund that does the heavy lifting, held in a custodial or teen account at a brokerage you plan to keep.

Start with a question your child can answer, such as who makes their favorite snack, and let the research lead to the purchase rather than the other way around. For how the rest of your child’s portfolio fits together, return to The GoodNest Guide to Investment Strategies & Portfolio Allocation.

Frequently asked questions

Can a child own fractional shares?

Yes, usually through a custodial account (UTMA or UGMA) that an adult opens and manages in the child’s name, at a brokerage that offers fractional trading in those accounts. Teens aged 13 to 17 can also buy fractional shares in teen accounts such as the Fidelity Youth Account. 529 plans and Trump Accounts don’t offer individual stocks, so they can’t hold slices of a single company.

How much money do you need to buy a fractional share?

It depends on the brokerage. Fidelity lets you buy slices of eligible stocks and ETFs listed on the NYSE or Nasdaq for as little as $1. Schwab Stock Slices starts at $5 per slice and covers only companies in the S&P 500, with up to 30 companies in one order.

Do fractional shares pay dividends?

Yes. Dividends are paid in proportion to the part of a share you own. In the SEC’s example, owning 0.75 of a share when the company pays a $10 dividend brings you $7.50. Many brokerages can reinvest those dividends automatically, buying a little more of the same stock.

Can you transfer fractional shares to another brokerage?

Generally not. Fractional shares usually have to be sold before an account moves to another firm. In a custodial account, that sale can create a taxable gain for your child, which is one more reason to choose a brokerage you plan to keep.

Are fractional shares riskier than whole shares?

The market risk is the same, because a slice rises and falls by the same percentage as a whole share. The extra limits are practical ones, such as restricted order types, missing voting rights, and the inability to transfer. The bigger risk is owning too few companies: in Bessembinder’s study of U.S. stocks from 1926 to 2016, 58% trailed Treasury bills over their lifetimes, which is why a learning slice should stay small next to a broad index fund.
