An equity position is an ownership stake in a company. Holding one entitles you to a proportional share of the company’s profits and, if it is ever wound up, whatever assets remain after every creditor has been paid. That last-in-line status is the defining feature: your financial outcome rises and falls with the business, with no guaranteed payment and no ceiling on the upside.
The people who hold equity are called residual claimants. Under the federal bankruptcy code, they sit at the bottom of the repayment hierarchy, behind nine tiers of creditor priority.1Office of the Law Revision Counsel. 11 USC 507 – Priorities If a company thrives, that residual can be enormous. If it fails, there may be nothing left.
How an Equity Stake Differs From a Loan
Lending money to a company by buying its bonds or extending it credit gives you a fixed legal claim to principal and interest regardless of how the business performs. Equity carries no such promise. You cannot demand a payment, and the company is not required to distribute profits even in a strong year. In exchange for accepting that risk, equity holders capture the full appreciation when the company grows in value.
Your ownership percentage is straightforward arithmetic. If a company has one million shares outstanding and you hold 100,000, you own ten percent of the business. That percentage sets your share of any distributed profits, your voting weight in corporate decisions, and your slice of anything left over if the company dissolves. Public equity takes the form of standardized shares trading on exchanges like the NYSE or NASDAQ, with prices moving by the second. Private stakes trade rarely, if at all, and depend on periodic appraisals or negotiated valuations.
The Main Types of Equity
Common Stock
Common stock is the standard ownership unit in most corporations. When someone says they own stock in a company without further qualification, they almost always mean common shares. Common stockholders get full voting rights, which means they elect the board of directors and vote on major corporate actions such as mergers. The tradeoff is that they stand last in line for dividends and liquidation proceeds. When the company does well, common stock captures the most appreciation because there is no cap on what the shares can be worth.
Preferred Stock
Preferred stock sits between debt and common equity. Preferred shareholders usually give up voting rights in exchange for two advantages: a priority claim on dividends, often at a fixed rate, and a higher position in the liquidation order. If dividends are declared, preferred holders get paid before common shareholders. If the company liquidates, preferred holders collect before common shareholders, though they still stand behind all creditors and bondholders.2SEC. Accredited Investors
In private companies, preferred stock often carries a liquidation preference, typically set at one times the original investment. With non-participating preferred, the investor chooses between taking the preference or converting to common. With participating preferred, the investor collects the preference and then takes a proportional share of what remains. Founders and early employees holding common stock should read this clause carefully, because a participating preference can significantly reduce the payout to common holders in an acquisition.
Private Equity and Partnership Interests
Not every equity position looks like stock. In limited liability companies and limited partnerships, ownership takes the form of membership interests or partnership units. These interests are governed by operating agreements or partnership agreements that spell out how profits are split, when distributions happen, and under what conditions an owner can sell or transfer their stake.
The tax treatment differs too. Corporations distribute dividends, reported on Form 1099-DIV. Partnerships and most LLCs pass their income through directly to the owners, who each receive a Schedule K-1 reporting their share of the entity’s profits, losses, deductions, and credits.3Internal Revenue Service. About Form 1065 – US Return of Partnership Income You owe tax on your share of partnership income whether or not the company actually distributes cash to you, which catches some first-time investors off guard.
What Rights Come With Ownership
Voting and Governance
Common stockholders elect the board of directors and vote on significant corporate decisions. Voting power is proportional to shares held, so a 5% owner has five times the influence of a 1% owner. Preferred shareholders typically do not vote, though some preferred agreements restore voting rights if the company misses a set number of dividend payments. Dual-class share structures, common in tech companies, can give founders outsized voting control relative to their economic ownership, so how much you own and how much say you have are not always aligned.
Dividends
Equity holders may receive a portion of profits through dividends, but no company is required to pay them. The board decides whether, when, and how much to distribute. A wildly profitable company can choose to reinvest every dollar instead. When dividends are declared, they are distributed proportionally, with preferred holders receiving their fixed payment before common holders.
Limited Liability
The most important protection for equity holders is limited liability. If the business goes bankrupt or gets sued for more than it can pay, your personal assets stay protected. The most you can lose is the money you put in. A shareholder who paid $50,000 for stock cannot be forced to cover the company’s debts from personal savings, a home, or other property.
The rare exception is veil-piercing, where a court disregards the corporate structure and holds owners personally responsible. That typically happens only when owners have mixed personal and company money, failed to maintain basic corporate records, or used the entity to commit fraud. For a passive investor holding publicly traded shares, veil-piercing is essentially a non-issue.
Inspection Rights
Shareholders generally have the right to inspect certain corporate records, including financial statements, meeting minutes, and shareholder lists. Specifics vary by state, but most require the shareholder to make a written request and state a proper purpose related to their ownership interest. This right cannot be eliminated by a company’s bylaws. Public companies satisfy much of it through mandatory SEC disclosure, so inspection rights matter most for private company shareholders who lack other visibility into the business.
How Your Percentage Can Shrink
Ownership percentages are not permanent. Every time a company issues new shares, whether to raise capital, compensate employees, or convert debt into equity, the total share count grows and your percentage falls. If you owned 100 out of 1,000 shares (10%) and the company issues 250 new shares to a new investor, you now own 100 out of 1,250 shares (8%). Your percentage dropped by two points even though you did not sell anything.
Dilution is not automatically bad. If the new capital makes the company substantially more valuable, a smaller slice of a bigger pie can be worth more in dollars than your original stake. A founder who goes from 100% of a $1 million company to 80% of a $2.5 million company has seen their position double in value despite the dilution. The danger appears when a company raises money at flat or declining valuations, or issues so many shares that early investors’ stakes shrink to the point of losing meaningful influence.
Some shareholder agreements include preemptive rights, which give existing owners the first chance to buy new shares before they are offered to outsiders. The purpose is to let you keep your percentage by purchasing your proportional share of any new issuance. Preemptive rights are not automatic in most states; they have to be built into the governing documents or negotiated into an investment agreement.
What Your Position Is Worth
Market Value and Book Value
For publicly traded companies, the market value of your equity is simply the share price multiplied by the number of shares you hold. That price moves constantly with investor expectations, industry conditions, and market sentiment. It is the most accessible measure, but it reflects what people believe the company is worth, not necessarily what its assets are worth today.
Book value takes the balance-sheet route: total assets minus total liabilities equals the net value attributable to shareholders. This accounting figure matters more in liquidation scenarios or when analyzing companies with significant tangible assets. For asset-light businesses such as software companies, book value can be a fraction of market value.
Return Metrics
Return on Equity (ROE) measures how much profit the company generates relative to total shareholder equity. A company earning $10 million on $50 million of shareholder equity has a 20% ROE. A consistently high ROE suggests management is putting shareholder capital to work well. A declining ROE alongside rising debt is a warning that the company may be borrowing to mask weakening profitability.
The Price-to-Book (P/B) ratio compares a stock’s market price to its book value per share. A P/B above 1.0 means the market is pricing the company higher than the accounting value of its net assets, common for growth companies or businesses with valuable intangibles like intellectual property. A P/B below 1.0 sometimes signals an undervalued stock, but it can also mean the market expects poor returns on those assets going forward.
Valuing a Private Stake
Valuing a private equity position is harder because there is no daily market price. Professional appraisals typically use discounted cash flow models, comparable company analysis, or a blend of both. These valuations are updated quarterly or annually, not in real time, and carry a meaningful margin of uncertainty. If you are buying into or selling a private company, the valuation methodology matters as much as the number it produces.
Taxes When You Sell
Capital Gains
When you sell equity for more than you paid, the profit is a capital gain. How much tax you owe depends largely on how long you held the position. Held more than one year, the gain qualifies as long-term and is taxed at preferential rates of 0%, 15%, or 20% depending on your taxable income.4Office of the Law Revision Counsel. 26 USC 1222 – Other Terms Relating to Capital Gains and Losses Held one year or less, the gain is short-term and taxed at your ordinary income rate, which can reach 37%. Your holding period starts the day after you acquire the shares and includes the day you sell them.5Internal Revenue Service. Topic No. 409 – Capital Gains and Losses That is worth tracking carefully if you are sitting on a large gain and approaching the one-year mark.
The Wash Sale Rule
If you sell equity at a loss, you can normally deduct it against other gains or up to $3,000 of ordinary income. The IRS disallows the deduction if you buy the same or a substantially identical security within 30 days before or after the sale. That creates a 61-day window during which you cannot harvest the tax loss and immediately repurchase the same position. The disallowed loss gets added to the cost basis of the replacement shares, so the benefit is deferred rather than lost.
Qualified Small Business Stock
If you hold equity in a qualifying small C-corporation, Section 1202 lets you exclude some or all of the gain from federal tax. The rules changed in mid-2025 when the One Big Beautiful Bill Act became law. For stock issued after July 4, 2025, the company must have gross assets below $75 million at issuance, up from $50 million. The exclusion is tiered by holding period: 50% at three years, 75% at four, and 100% at five or more. The maximum excludable gain per issuer is the greater of $15 million or ten times your adjusted basis. For stock issued before July 4, 2025, the older rules still apply: a five-year minimum holding period, a $50 million gross asset cap, and a $10 million exclusion limit. The benefit is narrowly targeted, but for founders and early investors, it can wipe out the federal tax bill on a successful exit.
Equity From an Employer
Many people hold their first equity position through employer compensation rather than a brokerage purchase. The tax rules differ by grant type, and the timing of when you owe taxes varies too.
Restricted Stock Units
RSUs are promises to deliver actual shares once a vesting schedule is satisfied, typically over three to four years. You owe nothing at grant. When shares vest and are delivered, their full market value on that date counts as ordinary income and appears on your W-2. Your employer withholds federal, state, Social Security, and Medicare taxes at vesting, often by automatically selling a portion of the newly vested shares to cover the bill. The federal supplemental withholding rate is 22% on income up to $1 million, but your actual tax rate may be higher depending on your total earnings. Any gain when you later sell above the vesting-day price is taxed as a capital gain.
ISOs and NSOs
Stock options give you the right to buy company shares at a fixed strike price set at grant. The two types have meaningfully different tax consequences.
Non-qualified stock options (NSOs) create a taxable event when you exercise. The spread between the strike price and the current market value is taxed as ordinary income, and your employer withholds on that spread like a bonus. Any additional gain when you sell the shares is a capital gain.
Incentive stock options (ISOs) get better treatment under the regular tax system: exercising triggers no ordinary income tax. However, the spread at exercise is a preference item for the alternative minimum tax.6Internal Revenue Service. Instructions for Form 6251 – Alternative Minimum Tax If you hold the shares at least two years from grant and one year from exercise, the entire gain when you sell is taxed at long-term capital gains rates. Selling before meeting both holding periods is a disqualifying disposition, which converts the spread into ordinary income and erases the ISO advantage.
Access Limits on Private Equity
Buying publicly traded stock is open to anyone with a brokerage account. Private equity is not. Federal securities law restricts most private offerings to accredited investors, defined by the SEC as those with a net worth above $1 million (excluding their primary residence) or annual income above $200,000 individually, or $300,000 jointly with a spouse or partner, in each of the two most recent years, with a reasonable expectation of the same in the current year.2SEC. Accredited Investors Holders of certain professional securities licenses (Series 7, 65, or 82) also qualify regardless of income or net worth.
Even after you acquire a private stake, selling it is restricted. If the company later goes public, shares from a private placement are classified as restricted securities. Under SEC Rule 144, you must hold restricted shares for at least six months after purchase before selling them in the public market if the company files regular reports with the SEC. If it does not file reports, the holding period extends to one year.7SEC. Rule 144 – Selling Restricted and Control Securities These restrictions exist to prevent privately placed shares from flooding the public market immediately after an IPO.
Private investors also face liquidity constraints public stockholders rarely think about. There is no exchange for selling a partnership interest with a click. Transfers are often restricted by the operating agreement and may require consent from other members or the general partner. Some private funds lock up capital for years with no early redemption. Treat private equity as money you will not be able to access for an extended period.
