Growth Stock

A growth stock is a share of common stock in a company that is expanding its revenue and earnings, or that investors expect to. Nothing about the security itself differs from any other share: the holder has the same residual claim on assets and earnings and the same vote. What differs is the expectation attached to the price, and the reason the shares are being held.

FINRA's investor education describes the category directly. Growth stocks "are issued by companies that are expanding, sometimes quite quickly, but in other cases over a longer period of time," and "typically, these are young companies in fairly new industries that are rapidly expanding." FINRA adds a qualification worth keeping: growth stocks "aren't always new companies," and can be established firms "poised for expansion—perhaps because of technological advances, a shift in strategy, movement into new markets, acquisitions or other factors."

A naming point that saves confusion. "Growth investing" and "growth stock" name the same subject from two directions, and FINRA teaches them together under one heading. The strategy is nothing more than deliberately holding more of these companies than a broad market fund would, so this page covers both the classification and what buying into it involves.

Where the return is supposed to come from, and what follows from that. FINRA puts the mechanism plainly: when a growth stock investment produces a positive return, "it's usually because the stock price moved up from where the investor originally bought it—and not because of dividends," because "most growth stock companies tend to plow gains directly back into the company rather than pay dividends." That is a choice about capital, not an oversight. A company that believes it can earn more on a dollar by building with it than a shareholder could earn elsewhere has a reason to keep it.

Two consequences follow. The whole return depends on someone later paying more for the shares, so nothing arrives in cash along the way. And because the price already reflects expected expansion, the price has further to fall if the expansion slows. FINRA states the resulting pattern in the context of a stock's beta, a measure of how a stock's movement compares with the market as a whole: "generally, growth stocks tend to be more volatile than value stocks."

There is no definition to look up, and the regulator's response to that is the most useful thing on this page. The SEC's investor glossary has no entry for it, FINRA describes the characteristics rather than setting a test, and the federal rule that does use the word declines to define it. That rule is 17 CFR 270.35d-1, the fund names rule, which treats a fund name including terms suggesting an investment focus in issuers with "particular characteristics (e.g., a name with terms such as 'growth' or 'value')" as materially deceptive unless the fund adopts a policy to invest, under normal circumstances, at least 80% of the value of its assets in accordance with that focus. The rule adds that any such term in the name must be "consistent with those terms' plain English meaning or established industry use," and states separately that a name can still be materially deceptive even where the fund adopts and follows the 80% policy.

So the SEC did not settle what growth means. It required each fund to settle it, disclose the settlement, and stand behind it with the bulk of the portfolio. The practical reading for an investor is that "growth" in a fund name is a pointer to a definition written in that fund's own documents rather than a shared standard, and the definitions differ: one screen may rank on revenue expansion, another on earnings expansion, another on a valuation measure. The compliance dates for the amended rule were extended to 11 June 2026 for fund groups with $1 billion or more in net assets and to 11 December 2026 for smaller fund groups, with the timing tied to each fund's fiscal year-end, so the phase-in is still running.

Membership is temporary and depends on price. Because most growth screens compare a company's valuation or its expansion rate against the rest of the market, a company can move into or out of the category without doing anything differently, simply because its share price or its peers moved. A stock is not permanently a growth stock in the way a bond is permanently a bond.

The portfolio question is separate from the classification question. A broad market fund weighted by company size already holds these companies, at the weight the market assigns them. Adding a fund devoted to them is therefore not filling a gap; it is deliberately holding more of something already owned, which is an active decision and needs an active reason.

An investor or an index provider applies a screen: measures such as revenue expansion, earnings expansion and the valuation the market is placing on them. Companies passing the screen are classed as growth companies, and a fund built on the screen holds them in some weighting. Because the screen is private to whoever wrote it, two funds applying the words "growth stock" to the same universe can produce different lists.

A hypothetical example of what the fund names rule actually requires. A fund with $500 million in assets calls itself a growth fund. Under the rule it must adopt a policy to invest, under normal circumstances, at least 80% of the value of its assets in accordance with the growth focus its name suggests. Eighty percent of $500 million is $400 million, so at least that much has to sit inside the fund's own definition of growth, leaving up to $100 million that need not.

Two details in that example matter more than the figure. The definition of growth being tested is the fund's own, written in its documents, not a standard set by the SEC. And the rule requires the fund to review whether its holdings still qualify at least quarterly and, if they no longer do, to come back into compliance within 90 consecutive days. So the 80% is a maintained position rather than a one-time check at launch.

Pros

• Expansion is the only route by which a company becomes materially larger, so this is where the largest long-run gains have to come from.
• Retained earnings produce no taxable distribution along the way, so in a taxable account the tax arrives when the holder chooses to sell.
• The characteristics FINRA names are observable in filings rather than a matter of opinion, so a reader can check a company against them.
• The category is broad enough to include established firms repositioning themselves, not just recent listings.

Cons

• The SEC's glossary has no entry and FINRA describes rather than defines, so two funds using the word can hold different companies and neither is mislabeled.
• FINRA states that growth stocks generally tend to be more volatile than value stocks, so the ride is rougher for the same amount of money.
• The return depends entirely on selling to a later buyer at a higher price, with nothing arriving as cash in the meantime.
• The price already contains the expected expansion, so meeting expectations may produce nothing and missing them can be expensive.
• A broad market fund already holds these companies at market weight, so a dedicated fund is an active bet rather than an added exposure.
