Equities are ownership shares in a corporation. Buy one and you own a fractional piece of the company, with a proportional claim on its profits, a vote on major decisions, and the right to sell your stake whenever a buyer will take it. That ownership is the source of both the higher long-run returns equities have historically produced and the volatility that comes with them. The S&P 500 has returned roughly 10% per year on average since 1957, but that average hides years with double-digit gains and years with steep losses.
What You Actually Own When You Buy a Share
A share represents fractional ownership of a corporation. Buy 100 shares of a company with 10 million shares outstanding and you own 0.001% of the business. Small, but real: you hold a proportional claim on earnings, a vote at the annual meeting, and the right to sell.
That claim is a residual one. If the company goes bankrupt, creditors get paid first. Banks, bondholders, suppliers, employees owed wages, and the IRS all sit ahead of shareholders in the distribution order set by federal bankruptcy law.1Office of the Law Revision Counsel. 11 U.S. Code 726 – Distribution of Property of the Estate In practice, common shareholders in a liquidation rarely recover anything.
The counterweight to that risk is limited liability. You can lose every dollar you put into a stock, but the company’s creditors cannot come after your bank account, house, or other assets. Courts pierce that protection only in narrow cases involving fraud or clear misuse of the corporate form. For an ordinary investor buying shares on a public exchange, personal exposure beyond the amount invested is essentially zero.
A company’s book equity is total assets minus total liabilities. That net figure is what belongs, on paper, to shareholders. Market prices rarely match book value, because investors are also pricing future earnings, growth, and much else that the balance sheet does not show.
Rights Attached to Stock Ownership
Voting
Public companies send out proxy statements before their annual meetings, and shareholders vote on directors, executive compensation packages, and shareholder-submitted resolutions on issues like governance and environmental policy. The standard structure is one vote per share. Some companies use dual-class share arrangements that give founders or insiders shares carrying 10 or even 50 votes each while public investors get one vote per share.2FINRA. Supervoters and Stocks: What Investors Should Know About Dual-Class Voting Structures That lets leadership keep control with a modest economic stake.
Dividends
A company can distribute part of its profits to shareholders as dividends, usually quarterly and expressed as a per-share dollar amount. Dividends are never guaranteed. The board decides whether to pay them, how much, and whether to cut or suspend them. Many highly profitable companies, including several of the largest technology firms, pay no dividend and reinvest everything in the business instead.
Price Appreciation
The other return channel is the share price itself. Buy at $50, sell at $80, and the $30 difference is a capital gain. Over long periods, stock prices tend to track corporate earnings growth, which is why equities have historically outpaced both inflation and bond returns. The trade-off is volatility. Prices can drop 30% or more in a single year, and individual companies can go to zero.
Common Stock and Preferred Stock
Corporate equity comes in two main forms, and they behave quite differently.
Common Stock
Common stock is what most people mean when they say “stock.” It makes up the vast majority of shares traded on public exchanges and carries the standard package: voting power, eligibility for dividends, and full exposure to price gains and losses. Common shareholders benefit most when a company thrives, because there is no ceiling on the share price. They also carry the most downside, standing behind every other class of investor in a bankruptcy.
Preferred Stock
Preferred stock sits between common stock and bonds. Preferred shareholders receive dividends before common shareholders, and those dividends are typically fixed at a set rate when the shares are issued. In a liquidation, preferred holders also have a senior claim on remaining assets compared to common shareholders, though they still rank behind debt holders.1Office of the Law Revision Counsel. 11 U.S. Code 726 – Distribution of Property of the Estate
The trade-off is usually the loss of voting rights and limited upside. Preferred prices tend to move less than common shares, so they participate less in a company’s growth. Many income-focused investors treat preferred shares almost like bonds with somewhat higher risk.
Convertible Preferred Stock
Some preferred shares include a conversion feature that lets the holder exchange them for a fixed number of common shares. The ratio is set at issuance. A preferred share with a $100 par value and a $25 conversion price converts into four common shares, giving the investor preferred-style income with the option to switch to common if the share price climbs high enough to make conversion worthwhile.
How Equities Differ From Debt
The clearest way to see what equity is is to compare it with debt. Buy a corporate bond and you are lending money to the company. It owes you fixed interest payments on a set schedule and must return your principal on a specific maturity date. Missing a payment is a default that can trigger lawsuits, restructuring, or bankruptcy.
Buy stock and nobody owes you anything on a schedule. Dividends are optional. There is no maturity date and no promise your original investment will come back. Returns depend on whether the share price rises and whether the board pays dividends. In exchange for that uncertainty, equity investors have historically earned higher returns over long stretches than bondholders.
The priority gap shows up hardest in distress. Bondholders and other creditors must be paid in full before equity holders receive anything from a bankrupt company’s remaining assets.1Office of the Law Revision Counsel. 11 U.S. Code 726 – Distribution of Property of the Estate That is the core equity trade: upside without a ceiling, last place when things fail.
Some securities straddle the line. Convertible bonds start as debt with regular interest payments but include an option to convert into common stock at a preset price. The holder collects interest while the share price is low and can switch to equity if the price rises enough. Companies use these hybrids to borrow at lower interest rates, because the conversion option itself has value.
How Equity Returns Are Taxed
Tax treatment is where equity investing gets more complicated than it first appears. Your bill depends on how long you held the shares and what type of income they produced.
Capital Gains
Sell a stock for more than you paid and the profit is a capital gain. Held for one year or less, it is short-term and taxed at your ordinary income rate, which ranges from 10% to 37% depending on your bracket. Held for more than a year, it qualifies for lower long-term capital gains rates.3Office of the Law Revision Counsel. 26 U.S. Code 1 – Tax Imposed
For 2026, the long-term capital gains brackets for single filers are:
- 0% on taxable income up to $49,450
- 15% on taxable income from $49,451 to $545,500
- 20% on taxable income above $545,500
For married couples filing jointly, the thresholds are $98,900, $613,700, and above $613,700 for the 0%, 15%, and 20% rates respectively.4Internal Revenue Service. Revenue Procedure 2025-32 The gap between short-term and long-term treatment is large. Selling a profitable position a day before the one-year mark can nearly double the tax on that gain.
Dividend Income
Dividends from U.S. stocks are taxed one of two ways. Qualified dividends get the same favorable rates as long-term capital gains. Ordinary (non-qualified) dividends are taxed at your regular income rate. To qualify for the lower rate, you have to hold the stock for at least 61 days during the 121-day window that starts 60 days before the ex-dividend date. For preferred stock, the required holding period is longer: at least 91 days within a 181-day window.5Internal Revenue Service. Instructions for Form 1099-DIV
The Net Investment Income Tax
Higher earners face an additional 3.8% surtax on investment income, including capital gains and dividends. It applies once modified adjusted gross income tops $200,000 for single filers or $250,000 for married couples filing jointly.6Office of the Law Revision Counsel. 26 U.S. Code 1411 – Imposition of Tax Those thresholds are set by statute and are not adjusted for inflation, so more taxpayers cross them each year.7Internal Revenue Service. Topic No. 559, Net Investment Income Tax Combined with the top 20% long-term rate, the surtax pushes the effective federal rate on investment income to 23.8% before state taxes.
The Wash Sale Rule
Sell a stock at a loss and you can normally deduct that loss against your gains. The IRS disallows the deduction, though, if you buy the same or a substantially identical stock within 30 days before or after the sale.8Office of the Law Revision Counsel. 26 U.S. Code 1091 – Loss From Wash Sales of Stock or Securities The disallowed loss isn’t lost for good. It gets added to the cost basis of the replacement shares, so you recognize it when you eventually sell those.9Internal Revenue Service. Case Study 1 – Wash Sales
How Shares Reach the Market
A stock’s life as a publicly traded security typically begins with an initial public offering. The company hires investment banks as underwriters, who set the initial share price based on investor interest gathered during a roadshow. The company issues new shares, collects the proceeds after fees, and trading opens on a public exchange.10Legal Information Institute. Initial Public Offering (IPO)
Some companies use a direct listing instead. There are no underwriters and no pre-negotiated price; the opening price is set entirely by supply and demand on the first trading day. Direct listings originally allowed only existing shareholders to sell, but a 2020 SEC action permitted the New York Stock Exchange to let companies sell new shares as part of a direct listing.11U.S. Securities and Exchange Commission. Order Setting Aside Action – NYSE Direct Listings
After issuance, shares change hands on the secondary market. The New York Stock Exchange, NASDAQ, and other venues match buyers and sellers throughout the trading day. That continuous trading gives investors liquidity and produces the real-time price that also feeds into a company’s ability to raise more capital and its value in a potential acquisition.
Foreign Equities and ADRs
American Depositary Receipts give U.S. investors a way to own foreign companies without opening an overseas brokerage account or holding foreign currency. A custodian bank holds the foreign shares and issues dollar-denominated ADRs that trade on U.S. exchanges. One ADR can represent a fraction of a foreign share, one share, or multiple shares.
Sponsored ADRs are set up with the foreign company’s cooperation, and the company files reports with the SEC. Unsponsored ADRs are created by a bank without the company’s involvement and come with fewer disclosures. Both carry pass-through custodian fees, typically one to three cents per share, automatically deducted from dividend payments. Foreign governments may also withhold tax on dividends before they reach your account, though you can often claim a U.S. tax credit for that withholding.
Disclosure Rules That Apply to Large Holders
Equity ownership triggers SEC reporting once it crosses certain lines. Any investor acquiring more than 5% of a company’s registered equity must file a Schedule 13D or 13G disclosing the holdings and intent.12U.S. Securities and Exchange Commission. Exchange Act Sections 13(d) and 13(g) Beneficial Ownership Reporting
Corporate insiders face tighter deadlines. Officers, directors, and holders of more than 10% of a company’s stock must file a Form 3 within 10 days of becoming an insider and a Form 4 within two business days of each subsequent trade in the company’s shares.13U.S. Securities and Exchange Commission. Insider Transactions and Forms 3, 4, and 5 Those filings are public, which is why insider buying and selling regularly turns up in financial news.
