In investing, equities are ownership shares in a company. Buying equity makes you a part-owner of the business, with a claim on a slice of its profits and assets proportional to how many shares you hold. “Equities” and “stocks” mean the same thing in everyday usage, and as an asset class they have delivered average annual returns of around 10% over the past century, which is why they anchor most long-term portfolios.
What You Actually Own
Buying equity is not the same as lending money to a company. A bondholder is a creditor owed a fixed repayment by a set date. An equity holder owns a permanent piece of the business itself, with a legal claim on its assets and on whatever earnings remain after the bills are paid.
Your ownership percentage is simply your shares divided by the total shares outstanding. Own ten thousand shares of a company that has issued one million, and you hold a one-percent stake. As the company grows more valuable, your one-percent slice grows in dollar terms alongside it.
The math also runs the other way. Companies sometimes issue additional shares through secondary offerings to raise capital, which increases the total share count and shrinks the fraction each existing share represents. If a company doubles its share count, a one-percent stake becomes half a percent unless you buy more. This dilution is one of the less obvious risks of equity ownership and worth watching in any company that frequently raises money by selling new shares.
How Equities Make Money
Stockholders earn returns in two ways: capital appreciation and dividends.
Capital appreciation is the rise in a share’s market price above what you paid. Buy at $50, watch the shares trade at $75 a year later, and you have an unrealized gain of $25 per share. The gain becomes real when you sell.
Dividends are cash payments a company distributes to shareholders out of its earnings, usually on a quarterly schedule. Not every company pays them. Younger, fast-growing firms often reinvest all profits back into the business, while more established companies tend to share a portion with investors. Both forms of return compound significantly over decades, which is why equities have historically been the primary wealth-building tool for individual investors.
Common Stock and Preferred Stock
Companies issue two main classes of shares.
Common stock is what most people mean by “stocks.” It carries voting rights on major corporate decisions and unlimited upside if the company performs well. The trade-off: common shareholders are last in line for any payout if the company runs into trouble, and dividends are never guaranteed.
Preferred stock sits between common equity and bonds. It typically pays a fixed dividend, which appeals to investors who want predictable income. Preferred shareholders usually cannot vote, but they receive dividends before common shareholders and have a higher claim on assets in a liquidation. Many preferred shares are cumulative, meaning any skipped dividend payments pile up and must be paid in full before common shareholders receive anything.
Where Equities Trade
Equities trade in two arenas with very different rules for who can participate.
Public equities are listed on regulated exchanges where anyone with a brokerage account can buy and sell during market hours. Prices update in real time and trades settle within a day. The Securities and Exchange Commission oversees these markets under the Securities Exchange Act of 1934, which requires listed companies to file detailed financial reports, including annual 10-K filings and quarterly 10-Q updates. That transparency is one of the main advantages of public markets: you can review a company’s revenue, debt, and expenses before investing a dollar.
Private equity involves ownership in companies not listed on any exchange. These investments are generally restricted to accredited investors, a category the SEC defines by income and net worth. Individuals typically qualify with annual income above $200,000 (or $300,000 jointly with a spouse) or a net worth above $1 million excluding a primary residence. Certain licensed financial professionals also qualify regardless of income. A company crosses from private to public through an Initial Public Offering, filed with the SEC on Form S-1.
Investors also sort public companies by size, using market capitalization (share price multiplied by shares outstanding). The tiers, as categorized by FINRA, run from mega-cap at $200 billion and above down to micro-cap under $250 million, with large-, mid-, and small-cap in between. Larger companies generally have more diversified revenue and easier access to capital; smaller ones can grow faster but are more vulnerable to downturns.
The Rights That Come With Shares
Common stock is more than a financial stake. It carries legal rights that let you influence how the company is run.
The most important is voting. Shareholders elect the board of directors and weigh in on major corporate actions such as mergers and executive compensation. Most votes happen at annual meetings, and if you cannot attend, the company sends a proxy statement (filed with the SEC as Schedule 14A) so you can vote remotely. Proxy materials list who is running for the board, what proposals are on the ballot, and how management recommends you vote.
Shareholders also have the right to receive dividends when the board declares them, to inspect certain corporate records, and to sue the company or its directors for breach of fiduciary duty. Some corporate charters grant preemptive rights, meaning existing shareholders get first crack at buying newly issued shares to maintain their ownership percentage before outsiders are offered any.
The Risks
Equities can lose value. That is the price of admission for their higher long-term return potential compared to bonds or savings accounts, and any honest conversation about stocks starts there.
Market-wide risk affects every stock regardless of how the underlying company is doing. A recession, rising interest rates, geopolitical conflict, or a broad shift in investor sentiment can drag entire markets down at once. You cannot diversify this away. You can only manage it by adjusting how much of your portfolio sits in equities versus less volatile assets like bonds or cash.
Company-specific risk is the chance something goes wrong at a particular business. A product recall, accounting scandal, key executive departure, or a new competitor can sink a single stock even while the broader market rises. Diversification handles this well: owning shares across many companies and sectors means one blowup will not wreck your entire portfolio. Index funds and exchange-traded funds that hold hundreds or thousands of stocks are the simplest way to achieve it.
Liquidity risk deserves a separate mention for private equity. Shares in private companies have no public exchange for quick sales, and investment commitments in private equity funds often lock up capital for a decade or more. Selling early, if permitted at all, usually means accepting a steep discount.
Bankruptcy is the ultimate downside. Equity holders sit at the bottom of the payment hierarchy. Under what bankruptcy law calls the absolute priority rule, secured creditors get paid first, unsecured creditors like bondholders come next, preferred shareholders follow, and common shareholders receive anything left over. In practice, particularly in Chapter 7 liquidations, there is rarely anything left by the time the line reaches common stock. Chapter 11 reorganizations sometimes preserve some equity value, but common stakes are typically reduced sharply or wiped out entirely. That priority structure is exactly why concentrating too much of a portfolio in a single company’s stock is dangerous, no matter how strong the company looks today.
How Equity Returns Are Taxed
The IRS taxes stock gains based on how long you held the shares before selling.
Short-term capital gains apply to shares held one year or less. They are taxed at your ordinary income tax rate, which for 2026 ranges from 10% to 37% depending on taxable income.
Long-term capital gains apply to shares held more than one year and receive preferential rates. For 2026:
- 0% on taxable income up to $49,450 for single filers ($98,900 for married couples filing jointly)
- 15% on taxable income from $49,451 to $545,500 for single filers ($98,901 to $613,700 for married filing jointly)
- 20% on taxable income above $545,500 for single filers ($613,700 for married filing jointly)
Qualified dividends receive the same favorable rates as long-term capital gains. To qualify, the stock must be held for at least 61 days during the 121-day window surrounding the ex-dividend date, and the dividend must be paid by a U.S. corporation or a qualifying foreign company. Dividends that do not meet those requirements are taxed as ordinary income.
High earners face an additional 3.8% net investment income tax on capital gains and dividends when modified adjusted gross income exceeds $200,000 for single filers or $250,000 for married couples filing jointly. Those thresholds are not indexed to inflation and have stayed the same since the tax took effect in 2013.
One rule catches new investors off guard: the wash-sale rule. Sell a stock at a loss and buy the same or a substantially identical stock within 30 days before or after the sale, and the IRS disallows the loss deduction. The disallowed loss is added to the cost basis of the replacement shares, so it is not permanently lost, but you cannot use it to offset gains on that year’s return.
