What Is a Preferred Stock Fund?

Updated July 9, 2026 6 min read

Most investing conversations split neatly into stocks or bonds, but there’s a security that borrows features from both — and a fund category built specifically to hold it.

The short answer

A preferred stock fund invests primarily in preferred securities, which are a class of shares that combine bond-like features, such as a fixed distribution, with equity-like features, such as being issued by a company rather than representing a loan. A dedicated fund exists because preferred securities behave differently enough from both common stock and traditional bonds that many investors prefer to access them as a distinct category rather than mixed into a general stock or bond fund.

Bond-like and equity-like features side by side

Preferred securities sit in an unusual middle position on a company’s balance sheet and in its capital structure.

Why a dedicated fund exists

Because preferred securities don’t fit cleanly into either a stock fund or a bond fund’s typical mandate, a specialized fund lets investors access this category directly rather than hoping a general fund happens to hold some. A preferred stock fund typically pools shares from many different issuers, which spreads out the risk of any single company deferring or cutting its distribution — a risk that would be far more concentrated in owning individual preferred shares directly. This pooling is similar in spirit to why a bond fund is often chosen over holding individual bonds.

How these funds tend to behave

Preferred securities are often sensitive to interest rate movements, somewhat similar to longer-term bonds, since their fixed distribution becomes more or less attractive as prevailing rates change. At the same time, because they’re issued by companies rather than being direct loan obligations, they can also be affected by the issuing company’s financial health in ways that resemble equity risk. That dual sensitivity is part of what makes preferred stock funds distinct from a typical bond fund or common stock fund — they don’t move in lockstep with either category.

Where it might fit in a portfolio

Some investors use a preferred stock fund as part of the income-oriented portion of a portfolio, given the typically higher distribution rates compared with many bonds. Others avoid the category specifically because of its added complexity and the risk that distributions can be deferred. As with any asset allocation decision, whether this fits depends on an investor’s goals, time horizon, and comfort with a security that doesn’t behave purely like a stock or purely like a bond.

A practical habit

A preferred stock fund is a way to access a security type that blends fixed-income and equity characteristics, pooled across many issuers to spread out company-specific risk. Its dual sensitivity to interest rates and issuer health is worth understanding fully before assuming it behaves like a typical bond or stock holding.
