Equities are ownership shares in a corporation. When you buy a share of stock, you own a slice of the company itself, which gives you a proportional claim on its profits, a vote on major decisions, and the right to sell your stake at any time. That ownership is what separates equities from bonds and other debt instruments: nobody owes you a fixed payment, and your returns rise or fall with the business. The S&P 500 has returned roughly 10% per year on average since 1957, but that figure hides large swings from year to year, and that volatility is the price of admission for equity returns.
What You Actually Own When You Buy a Share
An equity share represents fractional ownership of a corporation. Buy 100 shares of a company with 10 million shares outstanding, and you own 0.001% of it. The percentage sounds trivial, but it carries real legal weight: a proportional claim on earnings, a vote on major corporate decisions, and the right to sell whenever you choose.
Your ownership interest is what lawyers call a residual claim, which is a polite way of saying you are last in line. If the company goes bankrupt, every creditor is paid before shareholders see a dollar. Banks, bondholders, suppliers, employees owed wages, and the IRS all have priority. Federal bankruptcy law spells out six tiers of distribution, and equity holders sit below all of them.1Office of the Law Revision Counsel. 11 U.S. Code 726 – Distribution of Property of the Estate In practice, shareholders in a liquidation almost never recover anything.
The counterweight to that risk is limited liability. You can lose every dollar you put into a stock, but creditors cannot pursue your personal bank account, home, or other assets to cover the company’s debts. Courts will pierce that protection only in extreme cases involving fraud or blatant misuse of the corporate structure. For an ordinary investor buying shares on a public exchange, personal liability is essentially zero.
The Two Ways Equities Pay You
Equities generate returns through dividends and price appreciation. Both are optional in the sense that neither is guaranteed, and understanding how each works is the foundation for understanding the asset class.
When a company earns profits, its board can distribute part of them to shareholders as dividends, typically paid quarterly as a per-share dollar amount. Dividends are never promised. The board decides whether to pay them, how much to pay, and whether to cut or suspend them when business weakens. Several of the largest technology companies have historically paid no dividends at all, choosing to reinvest profits back into the business.
The other source of return is capital appreciation. Buy a share at $50, sell it at $80, and the $30 difference is your gain. Over long stretches, stock prices tend to track corporate earnings growth, which is why equities have historically outpaced inflation and bonds. The trade-off is volatility: stock prices can drop 30% or more in a single year, and individual companies can go to zero.
Shareholders also get a vote. Public companies solicit votes through proxy statements before the annual meeting, covering board elections, executive compensation, and sometimes shareholder-proposed resolutions. The standard arrangement is one vote per share, but some companies use dual-class structures that give founders or insiders dramatically more voting power, sometimes 10 or even 50 votes per share while public investors get one.2FINRA.

Common Stock and Preferred Stock
Corporate equity comes in two main forms, and they behave very differently.
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 full package: voting rights, eligibility for dividends, and complete exposure to both gains and losses. Common shareholders benefit most when a company thrives, because there is no ceiling on how high the price can go. They also absorb the most pain in a bankruptcy, sitting behind every other class of investor.
Preferred stock sits between common stock and bonds on the risk spectrum. Preferred shareholders receive dividends before common shareholders do, and those dividends are usually fixed at a set rate when the shares are issued. That predictable income is the main appeal. In a liquidation, preferred holders also rank above common shareholders, though still behind all 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, since preferred prices tend to move much less than common shares.
Some preferred shares include a conversion feature that lets the holder swap them for a set number of common shares. The ratio is locked in at issuance. A preferred share with a $100 par value and a $25 conversion price, for example, converts into four common shares. This blends preferred-style income with the option to switch to common stock if the price climbs enough to make conversion worthwhile.
Equities vs. Bonds
The deepest divide in corporate finance is between equity and debt, and it reduces to a single question: are you an owner or a lender?
Buy a corporate bond, and you are lending the company money. In return, it owes you fixed interest on a schedule and must repay your principal on a specific date. Those obligations are legally binding. Miss a payment and the company is in default, which can trigger litigation, restructuring, or bankruptcy.
Buy stock, and nobody owes you anything on a fixed schedule. Dividends are optional. There is no maturity date and no guaranteed return of your original investment. Your returns depend on whether the share price rises and whether the board chooses to pay dividends. In exchange for that uncertainty, equity investors have historically earned higher long-run returns than bondholders. The priority gap becomes stark in financial 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
Some securities blur the line. Convertible bonds start as debt with regular interest payments but include an option to convert into common stock at a predetermined price. The holder collects interest while the stock price is low and can switch to equity if the price climbs enough to make conversion attractive.
How the IRS Taxes Equity Investments
Taxes are where many new investors stumble. Your bill depends on how long you held the stock and what kind of income it produced.
Capital Gains
Sell a stock for more than you paid, and the profit is a capital gain. Hold the stock for one year or less and the gain is short-term, taxed at your ordinary income rate, which runs from 10% to 37%. Hold it for more than a year and the gain qualifies for lower long-term 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 Selling a profitable position one day before the one-year mark can nearly double your tax rate on the 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, you need to hold the stock for at least 61 days during the 121-day window starting 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
High earners pay an additional 3.8% surtax on investment income, including capital gains and dividends. It applies once your modified adjusted gross income exceeds $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, which means more taxpayers cross them each year.7Internal Revenue Service. Topic No. 559, Net Investment Income Tax Combined with the top 20% long-term capital gains rate, the surtax pushes the 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. But the IRS will not allow the deduction 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 This wash sale rule stops investors from harvesting a tax loss while immediately buying back the same position. The disallowed loss is not gone forever; it is added to the cost basis of the replacement shares, so you recognize it when you later sell those shares.9Internal Revenue Service.

Buying Foreign Companies Through ADRs
American Depositary Receipts let U.S. investors buy shares of foreign companies without opening overseas brokerage accounts or dealing in foreign currencies. A custodian bank holds the foreign shares and issues dollar-denominated ADRs that trade on U.S. exchanges just like domestic stocks. One ADR can represent a fraction of a foreign share, exactly one share, or multiple shares, depending on how the program is structured.
Sponsored ADRs are set up with the foreign company’s cooperation, meaning the company files reports with the SEC and follows U.S. disclosure rules. Unsponsored ADRs are created by a bank without the foreign company’s involvement and carry fewer protections. Both come with pass-through fees, typically one to three cents per share, that custodian banks charge for currency conversion and dividend processing. Foreign governments may also withhold tax on dividends before they reach your account, though you can often claim a credit for those taxes on your U.S. return.
When Owning Equities Triggers SEC Reporting
Equity ownership triggers mandatory SEC reporting once you cross certain thresholds. Any investor who acquires more than 5% of a company’s registered equity must file a Schedule 13D or 13G disclosing their holdings and intentions.10U.S. Securities and Exchange Commission. Exchange Act Sections 13(d) and 13(g) Beneficial Ownership Reporting The requirement exists to alert the market when someone is building a potentially controlling position.
Corporate insiders face even tighter rules. Officers, directors, and anyone who owns 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 any later trade in the company’s shares.11U.S. Securities and Exchange Commission. Insider Transactions and Forms 3, 4, and 5 These filings are public, which is why financial news headlines sometimes feature a CEO buying or selling company stock. A pattern of heavy insider buying is one signal that the people who know the company best are putting their own money behind it.
