What is a stock? What one share owns, from votes to profits

A stock is a unit of ownership in a corporation. Buy one share and you hold a small, fixed fraction of the business alongside every other shareholder: a fraction of its profits, a say in choosing the people who oversee it and a place in line for any dividend. The stocks hub covers how to invest in them. This guide explains what you actually own, how share types and voting work, what moves a share's price, and what one share of Apple amounted to in 2026.

What does owning a stock give you?

Owning a stock gives you a proportional claim on a company's profits and net assets, plus the voting and dividend rights attached to your class of shares. The claim is residual: shareholders come after employees, suppliers, lenders and the tax authorities, and own whatever is left over.

That leftover can be very large. Each year the board decides how much profit to pay out, how much to spend buying back shares and how much to reinvest, and all three serve the owners: cash paid out reaches them directly, while cash kept inside builds a business they collectively own. What a share does not give you is the right to use the company's property or to direct its managers, who answer to the board.

Your liability stops at your investment. If the company collapses, a fully paid share can fall to zero, but the company's creditors cannot pursue shareholders personally for its debts.

Few owners appear on the company's own books. Many brokers hold customers' shares in street name, so the register lists an intermediary, often Cede & Co., the nominee of the Depository Trust Company, while the broker's records show you as the beneficial owner. The broker credits your dividends and forwards annual reports and proxy materials. If you want your own name on the register, Investor.gov explains that you can move shares into the Direct Registration System, kept by the company's transfer agent, where the company offers it.

What is the difference between common and preferred stock?

Common stock usually carries the vote and the open-ended claim on profits; preferred stock usually has no vote but is paid first. When people say they own stock, they almost always mean common shares, the kind tracked on stock price pages.

Common stock can itself come in classes with different voting power. Some founders keep high-vote shares so they can control the board while selling most of the economic stake to the public. Usually each class still shares equally in profits, so the split affects control rather than the economics of each share.

The Alphabet stock page follows the Class C shares. Despite having no vote, they closed at $278.22 on October 30, 2026, against $279.84 for Class A.

How does shareholder voting work?

Most shareholders vote by proxy, sending instructions online, by phone or by mail before the annual meeting instead of attending it. Ahead of each meeting the company files a proxy statement with the SEC describing every item on the ballot and naming a record date. Only holders on that date can vote, so shares bought afterward cannot be voted at that meeting. The SEC notes that most annual meetings fall between March and June, though companies with other fiscal years meet at other times.

Microsoft's 2026 meeting, to be held online on December 8, shows the mechanics:

The gap between 7.4 billion shares and 73,581 holders of record shows how few owners are on the register; the rest hold through brokers and banks. If you hold in street name and your instructions have not arrived 10 days before the meeting, the SEC explains, your broker may vote your shares only on routine matters. Director elections are not routine, so uninstructed shares go uncounted there, which is why Microsoft's proxy says broker non-votes have no effect on its director, pay and shareholder-proposal items.

Not every vote binds the board. Microsoft's say-on-pay vote is advisory, and its four shareholder proposals ask for reports or a change of policy, with the board recommending against all four.

Do all stocks pay dividends?

No: a company pays a dividend only when its board declares one, and many profitable companies prefer to reinvest or buy back shares instead. A dividend is a decision rather than a debt, nothing is owed until it is declared, and a later board meeting can lift, trim or scrap it.

Apple pays $0.27 a share each quarter, or $1.08 a year, roughly an eighth of its trailing earnings per share. It hands far more back through buybacks, as the worked example below shows.

Three companion guides cover the details. Who receives a declared payment depends on the record and ex-dividend dates in dividend dates explained. Judging a payout by its yield, payout ratio and growth is the subject of dividend investing basics, and the tax rate depends on whether a payment counts as qualified or ordinary. Reinvesting payouts automatically is covered in dividend reinvestment plans.

How are stock prices determined?

A stock's price is the last price at which a buyer and a seller agreed to trade, and it moves whenever one side grows more eager. Once its shares are listed, a company does not set their price and receives nothing when investors trade them with each other; its stock brings in cash only when it sells new shares.

Buyers and sellers meet through exchanges and other venues, described in how the stock market works. Each order reflects a judgment about three things: how much the company will earn in the years ahead, how confident anyone can be about that, and what the same money could earn elsewhere.

The third point is where interest rates come in. When safe yields rise, a dollar of profit expected in 2035 is worth less today, so investors tend to pay a lower multiple of current earnings, other things being equal. And because prices already contain expectations, results move a stock only to the extent that they differ from what was expected: a record quarter can send the price down if investors had counted on more.

Two summary numbers come straight from the price. Divide it by earnings per share and you get the price-to-earnings ratio, the subject of the P/E ratio guide; multiply it by the share count and you get the company's market value, its market capitalization.

Over days and weeks, prices also move for reasons that have little to do with the business, such as a large fund selling, a stock joining or leaving a major index, or a burst of buying after a headline. How to read a stock quote shows where those moves appear on a quote screen.

What does one share of a large company represent?

One Apple share is a claim on about one 14.6-billionth of the company, which earned $8.72 per diluted share in the 12 months to June 2026. Apple makes a useful case because it is among the world's most valuable companies and reports its share count every quarter. The figures below come from its 10-Q for the quarter ended June 27, 2026, its 10-K for fiscal 2025 and Nasdaq's closing price on October 30, 2026.

Buybacks make each remaining share a bigger slice. Apple's share count fell from 14,773,260,000 on September 27, 2025 to 14,608,963,000 on June 27, 2026, a drop of 1.1%, so every remaining share's claim grew by about 1.1% without its owner doing anything. In those nine months Apple spent $61.8 billion repurchasing 215 million shares, about $287 each on average, and in April 2026 its board authorized another $100 billion.

Apple was due to report its September-quarter results on November 2, 2026, which will update every line of the table, though the method stays the same. Multiply the share count by $344.79 (Nov 2, 2026) for a current market value, or see Apple's stock page for the price history.

How is a stock different from a bond or a fund?

A stock makes you a part-owner with an uncapped but uncertain return; a bond makes you a lender with a fixed claim. A stock fund or ETF changes something else: it holds many companies, so one failure costs you only that company's share of the basket.

Many investors own stocks both ways, through individual shares and through funds in a brokerage account or retirement plan. How to buy stocks walks through a first purchase, and crypto vs stocks sets shares against digital assets.

What are the risks of owning a stock?

A single stock can lose most or all of its value, and in a liquidation common shareholders are paid last, often receiving nothing. Investor.gov describes the order: bondholders first, then preferred holders, then common stockholders, who get whatever is left.

• Price swings. Investor.gov notes that large-company stocks as a group have lost money in about one year out of three, and bear markets and corrections covers the deeper drops.
• Company risk. A lawsuit, a failed product or an accounting problem can sink one stock while the wider market rises. Owning many companies, directly or through a fund, spreads that risk.
• Dilution. New shares issued to raise money or pay employees shrink each existing share's slice, the reverse of a buyback.
• Limited say. Dual-class structures such as Alphabet's can leave public shareholders with little influence over the board.
• No backstop for losses. Brokerage failure is handled separately: SIPC restores missing securities and cash up to $500,000 per customer, including up to $250,000 in cash, but no program reimburses a fall in a share's price, as FDIC vs SIPC explains.

The wider set of risks, from inflation to liquidity, is laid out in types of investment risk.
