Can I buy a single share of stock?

Can I buy a single share of stock? Yes — an investor can buy one whole share of a publicly traded company if they have a funded brokerage account and sufficient funds. Beyond that, many modern brokers also let you buy fractional shares (partial ownership based on a dollar amount) so you can invest with very small sums and still access high-priced stocks. This article explains the definitions, how to buy one whole share or a fractional share, costs and limits, corporate actions, tax and settlement details, broker implementations, practical steps, risks and alternatives, and relevant regulatory and recordkeeping points.

As you read, you’ll learn how to decide whether buying a single share or a fractional portion makes sense for your goals, how brokers execute these orders, and why Bitget can be a practical choice for trading and storage when you want an integrated experience (trading, custody, and Web3 wallet access).

Definition and background

A "share" is a unit of ownership in a corporation. Owning one share of a company gives you a proportional claim on the company’s assets and earnings, subject to shareholder rights defined by the company and local corporate law. Historically, the tradable minimum was one whole share: exchanges, clearing systems, and brokerage back office systems treated shares as indivisible units.

Technological and brokerage innovations changed that model. Advances in order routing, internal ledgering and custody systems, batch settlement, and dollar-based order handling enabled brokers to offer fractional-share trading. Fractional shares are not always recorded on the exchange as fractional units; brokers often keep internal ledgers that allocate fractional ownership to customer accounts and aggregate or round trades at the broker level for exchange settlement.

The net effect is greater accessibility: investors with small amounts of cash can buy a slice of a high-priced stock, set up automated recurring investments, and build diversified portfolios without needing to buy whole shares of each company.

Buying a single whole share

Short answer: yes. You can buy a single full share on most exchanges if you have an account and the required funds.

Key points when buying one whole share:

Account and funding: open a brokerage account (or use Bitget) and deposit sufficient funds. Account verification and funding may take time depending on payment method.
Eligible securities: most US-listed stocks and ETFs are available to buy one whole share; some OTC or restricted securities may have limitations.
Order types: you can place a market order (buy at prevailing price) or a limit order (buy only at or below a specified price). Market orders execute quickly but may suffer price slippage on volatile or low-liquidity names.
Broker minimums and commissions: many brokers have $0 commissions on online trades for US-listed stocks, but some may impose small fees, account minimums, or inactivity charges. For very small purchases, fixed fees or minimum commissions can materially reduce returns.
Settlement: trade settlement follows the market’s settlement cycle (T+1 for US equities as of 2024), meaning trade ownership and funds movement finalize after the settlement window.

Buying a single share is straightforward for typical retail investors and is often the simplest way to own a company outright rather than holding pooled instruments.

Fractional shares — what they are and how they work

Definition: fractional shares are a portion of a whole share that represent proportionate ownership in a stock or ETF. They let you invest by dollar amount (for example, $10) rather than by share quantity (for example, 0.153 shares).

How fractional shares are ordered:

Dollar-based orders vs share-quantity orders: fractional trading often enables dollar-based orders ("buy $25 of Company X") instead of specifying a share count. That makes it natural for recurring investments and proportional portfolio rebalancing.
Execution mechanics: brokers handle fractional orders in several ways. Some execute a market or limit order on the exchange for the equivalent whole-share amount; others aggregate many small dollar orders into block trades and allocate fractional pieces internally. Execution price and timing can therefore depend on the broker’s matching and batching process.
Real-time fills vs aggregation: some brokers provide near-instant fills at current market prices, while others batch fractional requests at certain intervals (for example, at market open or close) and then allocate executed prices to customer accounts. Batching can introduce a time-lag or slight price variance compared with immediate whole-share trades.

Fractional shares enable:

Dollar-based investing and recurring purchases (e.g., $50 per paycheck)
Access to high-priced stocks without paying for a full share
Easier diversification with small capital amounts

Limitations often include eligibility restrictions (some brokers limit fractional trading to major exchange-listed US stocks and ETFs) and transferability constraints (fractional holdings may not be moved as-is between brokers).

Broker implementations and examples

Different brokerage firms implement fractional-share trading with varied rules. Below are representative examples of implementation styles and common differences — these are illustrative of how the market evolved; you should always check your chosen broker’s current terms.

Dollar-based slices: some brokers let customers buy fractional slices of individual stocks by specifying a dollar amount. These systems facilitate recurring investments and simple allocation tools.
Percentage or proportional purchases: a broker may let you buy a percentage of your portfolio in a particular stock, calculated into fractional shares.
Aggregation and internal ledgering: many brokers (especially those offering free fractional trades) internally aggregate orders for efficiency, executing whole-share block trades and updating customer ledgers to reflect fractional positions.

Examples of broker differences you should check before trading:

Minimums: some brokers set a minimum purchase amount for fractional buys (e.g., $1, $5, or $10). Others offer no minimum for fractional trades.
Eligible securities: brokers commonly restrict fractional trading to US exchange-listed common stocks and ETFs; newly issued IPOs, ADRs, pink-sheet stocks, or certain thinly-traded securities may be excluded.
Order types supported: many brokers support market orders for fractional trades; fewer support limit orders for fractional quantities or advanced order types.
Platform availability: fractional trading may be available on web and mobile apps but not via legacy desktop platforms or API trading.

Where Bitget fits: Bitget provides modern brokerage and custody features and supports dollar-based and share-quantity trading for a wide set of securities and tokenized assets. If you plan to trade or custody assets and want integrated wallet support for Web3 interactions, Bitget and Bitget Wallet offer combined convenience.

Order types, execution timing, and limitations for fractional trades

Common characteristics:

Order types: market orders are the most widely supported for fractional trades. Some brokers provide limit orders on fractional shares, but limit support can be limited or handled differently (for example, partial fills only if the executed aggregated trade matches the limit price).
Market hours vs after-hours: many brokers only permit fractional trades during regular market hours; extended-hours fractional trading is less common because of liquidity and pricing complexities.
Batching effects: when brokers batch fractional orders, the execution time (and final per-share price) depends on the timing of the underlying block trade. That can cause a small difference between an immediately executed whole-share market order placed directly on the exchange and a fractional trade executed via batching.
Rounding and allocation: because exchanges typically trade whole shares, brokers round allocations when creating customer-level fractional balances. Brokers’ internal records show fractional quantities; exchange-level positions are usually aggregated.

Limitations to watch for:

Not all order types or advanced instructions (stop-loss, trailing stops, complex multi-leg orders) may be supported on fractional shares.
Brokers may limit fractional trading to certain account types (e.g., retail taxable accounts vs retirement accounts).

Costs, fees, and price impact

Transaction costs on a per-dollar basis matter more when buying small amounts (such as a single share or a small fractional piece). Key cost factors:

Commissions: many brokers currently offer $0 commission on online trades for major stocks and ETFs, but always confirm as policies vary.
Spreads and price improvement: when you place a market order, you effectively pay the spread between the bid and ask. Some brokers provide price improvement, meaning the execution price is better than the national best bid or offer. For tiny trades, the spread can be a fixed percentage of your trade amount.
Fixed fees: if a broker charges a fixed commission (for example, $1 or $2 per trade), that fee disproportionately affects small purchases. Consider fee-free or dollar-based brokers for very small investments.
Fractional rounding and internal overhead: when brokers aggregate and allocate fractional trades, small rounding differences and internal execution costs can slightly change the effective per-share price.

Practical guidance:

For very small investments, prefer brokers that offer $0 commissions and low or no minimums for fractional trades.
Compare effective cost as a percentage of the purchase amount. A $1 fee on a $10 buy is 10% of your investment — often unacceptable.
Understand whether the broker offers price improvement and whether fractional trades are executed immediately or batched.

Dividends and corporate actions on fractional shares

Dividends: fractional-share holders usually receive dividends pro rata. If you own 0.25 shares and the company pays $1 per share, you should receive $0.25 (less any withholding or tax if applicable). Brokers generally credit dividend payments to your account in cash.

Stock splits and reverse splits: corporate actions are applied proportionally. If a company does a 2-for-1 split, a fractional holding of 0.25 shares becomes 0.5 shares. Reverse splits can create fractional results that brokers handle according to their terms (often cashing out tiny odd lots or adjusting ledger balances).

Mergers, acquisitions and spin-offs: brokers typically handle these pro rata, adjusting fractional holdings to reflect the corporate action. Exact treatment can vary for complex actions; check broker notices and account statements.

Recordkeeping: brokers record fractional-share dividends and corporate-action adjustments on account statements, often monthly. Keep statements for tax reporting.

Benefits of buying a single share or fractional shares

Accessibility: invest with very small amounts; fractional shares let you buy into expensive stocks without saving for a full share.
Diversification: spread a small investment across multiple companies (for example, buy $20 in five stocks rather than one $100 share), reducing single-stock exposure.
Recurring investments: dollar-based fractional purchases make dollar-cost averaging and automated investing simple.
Exposure to high-priced names: buy a slice of a market leader without needing dozens of whole shares.
Convenience for dividend reinvestment: DRIPs combined with fractional capability let brokers reinvest dividends into fractional shares automatically.

Drawbacks and risks

Under-diversification: buying only one company (one share) concentrates company-specific risk. Single-share holdings are more volatile than diversified funds.
Execution differences: fractional trades might be batched or internally allocated, which can produce execution price differences relative to whole-share exchange fills.
Platform restrictions: some brokers restrict eligible securities, order types, or account types for fractional trading.
Transferability limits: fractional holdings are often tied to the broker’s internal ledger and may not be transferable to another broker as fractional units; the broker may cash out or convert them to whole-share equivalents before transfer.
Behavioral risks: owning single companies can encourage short-term trading, overconfidence, or emotional decision-making.

Alternatives to buying a single share

If buying one share (or a fractional share) is not ideal for your goals, consider alternatives:

ETFs and index funds: buy instant diversification across hundreds or thousands of stocks with a single trade; many ETFs are available as fractional shares too.
Mutual funds: offer pooled exposure and professional management; be mindful of minimums and expense ratios.
Dividend reinvestment plans (DRIPs): company-sponsored DRIPs allow reinvesting dividends into fractional shares over time.
Robo-advisors: automated portfolio managers accept dollar contributions and allocate across diversified ETFs and funds according to your risk profile.

Each option has tradeoffs in fees, tax handling, and liquidity.

Practical step-by-step: how to buy one share (or a fractional share)

Choose a broker: evaluate fees, fractional-share support, eligible securities, app experience, and custody features. Consider Bitget if you want an integrated platform with trading and Web3 wallet support.
Open an account: register, verify identity, and choose an account type (taxable brokerage, retirement account, etc.).
Fund the account: transfer funds by bank transfer, debit card, or other supported methods. Timing varies by method.
Check eligibility: confirm whether the stock you want is eligible for fractional trading and whether your account type supports it.
Decide order format: choose dollar amount (for fractional) or share quantity (for full share). Select order type (market vs limit).
Submit the order: place the trade during the allowed trading window.
Monitor settlement and holdings: after execution, confirm the resulting share or fractional holding in your account. Keep records for tax reporting.
Set up recurring investments if desired: many brokers let you automate purchases by dollar amount.

Regulatory, recordkeeping and investor-protection considerations

SEC guidance: regulatory bodies have issued investor bulletins noting that fractional-share availability, execution, and handling vary by broker. Availability is not uniform, and brokers differ in how they execute and apply corporate actions.
Investor protection: fractional-share holdings at regulated brokers are generally covered by the same investor-protection frameworks (such as SIPC protection in the U.S. for certain broker failures) as whole-share holdings, subject to the broker’s custodial arrangements. Always confirm the specific protections your broker offers.
Recordkeeping: brokers provide trade confirmations and periodic statements that reflect fractional quantities, cash dividends, and corporate action results. Keep these for tax and audit purposes.
Differences by jurisdiction: rules and protections differ across countries; check local regulation and broker terms.

Taxes and settlement

Settlement cycles: settlement determines when ownership legally transfers and when proceeds are delivered. As of 2024, US equities trade on a T+1 settlement cycle (trade date plus one business day). Other markets may operate on different cycles.
Taxable events: dividends from fractional shares are taxable like dividends from whole shares; capital gains/losses from selling fractional shares are taxable and must be reported.
Cost basis: maintain accurate cost-basis records for fractional purchases. Brokers typically provide cost basis reporting, but you should keep records, especially if you trade across multiple brokers.
Withholding and cross-border taxes: nonresident investors may face withholding on dividends; ensure tax forms and withholding are handled correctly by your broker.

Frequently asked questions (short Q&A)

Q: Is one share enough to invest? A: One share is a start, but diversification reduces risk. Consider your goals and whether one share matches your risk tolerance.

Q: Will fractional shares earn dividends? A: Generally yes — dividends and corporate actions are applied pro rata to fractional holdings and are credited to your account.

Q: Can I transfer fractional shares to another broker? A: Transfers of fractional holdings can be limited. Many brokers do not allow exact fractional transfers; they may cash out fractional portions or convert them prior to transfer. Confirm with both brokers.

Q: Are fractional shares available after-hours? A: Many brokers restrict fractional trading to regular market hours; extended-hours fractional trading is less common. Check broker rules.

Q: How do I know if a stock is eligible for fractional buying? A: Check your broker’s eligible securities list or search the stock within your brokerage app; eligibility varies by broker and by security.

Notes and caveats

Availability and exact rules for buying one share or fractional shares vary by broker and by jurisdiction. The details in this guide are general and educational. Confirm the specifics (fees, eligible securities, order types, tax reporting, and corporate-action procedures) with your chosen brokerage before trading.

As of December 31, 2025, according to Motley Fool market coverage, W.P. Carey (ticker WPC) showed a dividend yield of roughly 5.48% and a share price near $65.28 with a market cap near $14B; the coverage highlighted the REIT’s stable net-lease cash flows and dividend support. The same reporting noted Amazon (ticker AMZN) had a market capitalization around $2.48 trillion and growing cloud revenue that analysts described as a central driver for future growth. These examples illustrate why fractional and whole-share access matters: expensive or high-profile names (like Amazon) may be cost-prohibitive at the whole-share level for some investors, while dividend-oriented names (like W.P. Carey) may attract investors seeking income even at single-share or fractional-share sizes. (Reporting date: December 31, 2025; source: Motley Fool market coverage.)

Further practical guidance and closing notes

If you’re deciding between buying one whole share or fractional shares:

Check the broker’s fee structure — small fixed fees are a big drag on small purchases.
Decide whether you value immediate execution (whole-share market order) or the convenience of dollar-based recurring investing (fractional).
Consider diversification: for small balances, ETFs or fractional ETFs often provide better risk-adjusted exposure than a single company.
Verify corporate-action handling and dividend crediting for fractional holdings.
