Publicly Traded Stocks

How it works

A company sells shares to the public through a listing, most commonly an initial public offering. After that, shares trade between investors on an exchange, and the company itself receives no further money from ordinary secondary-market trades — buying Apple stock today pays another shareholder, not Apple.

Each share is a proportional claim on the company's residual value: what is left of profits and assets after employees, suppliers, lenders and any preferred shareholders are paid. The board decides what to do with that residual profit — reinvest it in the business, pay down debt, repurchase shares, or declare a dividend. Nothing in corporate law obliges the board to distribute anything to common shareholders.

Buybacks reduce the number of shares outstanding, so each remaining share represents a larger slice of the company. Retained earnings that are reinvested at a good return raise the value of that claim without any cash changing hands or any tax event occurring. Shareholders also hold voting rights on the board of directors and certain corporate actions, normally exercised by mailed or electronic proxy rather than in person; dual-class share structures can leave public holders with a small fraction of the voting power of founders or insiders.

Shares are typically held in street name at a brokerage rather than as physical certificates, and are protected in the US by SIPC coverage if the broker itself fails — that coverage does not protect against the stock losing value. US equity trades settle on a one-business-day cycle. The mechanics of dividend policy specifically, including payout ratios and dividend growth records, are covered in a separate part of this library.

What it pays

Total return on a stock is price change plus any dividends paid. A company that never pays a dividend can still deliver a substantial total return entirely through growth in business value and reduction of share count — Berkshire Hathaway is the standard example.

Dividends are declared at the board's discretion and can be raised, held flat, cut, or eliminated at any time. They are not a contractual obligation the way a bond coupon is; a missed dividend is not a default. Repurchases return cash to shareholders as a group without creating a taxable event for holders who do not sell, which is why share count reduction matters as much as total company earnings when judging what an owner actually receives.

Because prices are set continuously by other investors rather than by any formula tied to earnings, returns arrive irregularly and can be sharply negative over periods of several years even when the underlying business is performing normally. The shareholder is last in line for any distribution: in a bankruptcy, equity is paid only after every creditor and preferred holder is made whole, which in practice frequently means equity holders receive nothing at all.

Costs and taxes

Commission-free trading is now standard at major US brokers. The real costs are less visible: the bid-ask spread paid on every trade, and for pooled vehicles like funds, an ongoing expense ratio charged against assets rather than billed directly.

Under US federal tax law, qualified dividends are taxed at long-term capital gains rates once holding-period requirements are met, while dividends that do not qualify and short-term gains are taxed at ordinary income rates. A capital gain is taxed only when the position is sold — an unrealized gain, no matter how large, is not a taxable event. Gains on shares held more than one year qualify for long-term capital gains treatment.

The wash sale rule disallows a claimed loss if substantially identical securities are bought within thirty days before or after the sale that generated the loss; the disallowed loss is added to the cost basis of the replacement shares instead of being lost outright. Shares held inside a tax-advantaged retirement account, such as an IRA or 401(k), are not taxed on dividends or gains while inside the account — tax is assessed later, under the withdrawal rules of that account type.

Non-US investors in US stocks generally face withholding on dividends at a rate set by tax treaty. US investors holding foreign shares may face foreign withholding taxes on dividends, often offset in whole or part by a foreign tax credit claimed on the US return.

Liquidity and time commitment

Publicly traded stock is the most liquid structure in this category. Shares of large, actively traded companies can normally be sold within seconds during market hours, with cash proceeds settling the next business day.

Liquidity is not uniform across the asset class. Thinly traded small-company shares can have wide bid-ask spreads and can move sharply, or gap, on order sizes that would barely register in a large-cap name.

The effort required is genuinely minimal because professional management runs the operating business day to day. The shareholder's ongoing tasks are optional: monitoring the position, voting proxies if desired, and reporting dividends and sales for tax purposes. There are no capital calls, no lock-up periods, no consent required from anyone to sell, and no minimum holding period imposed by the instrument itself.

The practical time cost is behavioral rather than structural. A price visible every second of every trading day invites trading activity that an illiquid private ownership stake simply does not offer the chance to make.

How it goes wrong

The core risk is permanent capital loss when the underlying business deteriorates — a falling share price recovers only if the company's fortunes recover, and some companies never do. Dilution from new share issuance or heavy stock-based compensation quietly shrinks each existing holder's proportional claim even while the company's total value is stable or growing.

A company can be genuinely and durably profitable while paying its owners nothing for years, because ownership of common stock carries no right to receive cash. Concentration in a single company means an idiosyncratic event — a lost patent lawsuit, an accounting fraud, an adverse regulatory ruling — can take a position to zero on a day the broader market is unaffected or even rising.

In bankruptcy, common equity ranks behind every creditor and every preferred shareholder, and is commonly wiped out entirely even in reorganizations where the underlying business continues operating under new ownership. Finally, the volatility inherent in a continuously priced instrument is often realized through the holder's own behavior: an illiquid private stake cannot be sold in a panic at the worst possible moment, while a listed stock always can.
