What Is Preferred Stock? A Plain English Guide

March 10, 2026·6 min read·By Robin Gillingham

Most investors are familiar with two types of securities: common stock and bonds. Preferred stock is a hybrid that draws features from both. It is widely used by corporations to raise capital and underpins the structure of newer income instruments like STRC and SATA.

Where preferred stock sits in the capital structure

When a company raises money, it can borrow through bonds, sell ownership through common stock, or issue preferred stock — a middle path. The term "preferred" refers to payment priority. If dividends are paid or the company is liquidated, preferred stockholders receive their payment before common stockholders. Bondholders, however, still rank above preferred stockholders. This places preferred equity firmly in the middle of the capital stack: more protected than common stock, less senior than debt.

Fixed dividends and income predictability

Preferred stock carries a fixed dividend expressed as a percentage of the issue (par) price. This payment is agreed at issuance and does not fluctuate with company profits. Unlike common stock dividends — which can be raised, cut, or eliminated at will — preferred dividends offer a level of consistency that makes them attractive to income-focused investors.

In most structures, preferred stockholders receive no voting rights. They trade governance influence for income stability. For investors primarily interested in reliable cash flow rather than corporate control, this is a straightforward tradeoff.

Cumulative versus non-cumulative dividends

One critical distinction between preferred stock structures is whether dividends are cumulative or non-cumulative.

With cumulative preferred stock, if the issuer misses a dividend payment, the unpaid amount accumulates as an obligation. Before common stockholders receive anything, all back-owed preferred dividends must be settled. Non-cumulative preferred stock offers no such protection: a missed payment is simply gone.

This distinction matters considerably when assessing downside risk. Non-cumulative structures offer less protection if an issuer encounters financial difficulty.

Perpetual versus term preferred stock

Perpetual preferred stock has no maturity date. The issuer pays dividends indefinitely, and the stock does not automatically redeem. Total return depends almost entirely on dividend income — there is no built-in capital return event to anchor pricing.

Term preferred stock has a fixed maturity at which the company redeems stock at par value, similar to a bond. This creates a known endpoint that affects both price behaviour and yield calculation.

STRC, issued by Strategy, is a perpetual preferred stock. This means its effective yield — your actual return based on the price you pay — can shift over time even if the dividend itself remains unchanged.

How preferred stock compares to bonds

Bonds are debt instruments. The issuer is legally obligated to pay interest and return principal. Missing a bond payment triggers a default. Preferred dividends are equity payments — they can theoretically be suspended without triggering a default event. In practice, suspending preferred dividends is severely damaging to an issuer's reputation and its ability to raise future capital, so issuers treat these obligations seriously.

To compensate investors for bearing slightly more risk than bondholders, preferred stock typically carries a higher yield than bonds from the same issuer. This yield premium is the return for accepting a lower position in the capital stack.

Adjustable-rate preferred stock

Some preferred stock has a variable dividend rate that adjusts periodically in response to market conditions. STRC operates this way — its dividend rate is reviewed monthly to keep the instrument trading close to its $100 par value. When the price drifts below par, the rate adjusts upward to attract buyers; when it drifts above par, the rate adjusts down. This mechanism is designed to reduce price volatility while maintaining a competitive income stream.

Why this matters for income investors

If you are evaluating STRC or SATA, you are looking at preferred equity instruments. The three metrics that matter most are: the stated yield (annual dividend as a percentage of par), the effective yield (annual dividend as a percentage of the current market price), and the par proximity (how close the instrument trades to its issue price at any given time).

The STRC hub and SATA hub show you all three metrics in real time. Understanding the preferred equity framework means you know exactly what you are looking at — and why the price matters as much as the dividend.
