Growth Stock

A growth stock is a share in a company whose revenue and earnings are expected to grow significantly faster than those of the average company in the market. Investors buy growth stocks mainly for price appreciation rather than income: such companies usually reinvest their profits in expansion instead of paying them out, so many pay a small dividend or none at all.

Because buyers are paying today for profits they expect in future, growth stocks typically trade at high multiples of current earnings, sales or book value. They are the counterpart of the value stock, which looks cheap on those same measures. The strategy of seeking them out is called growth investing, and funds built around it are known as growth-style funds. A growth stock can be any size, from a young small-cap stock to a technology giant among the large-cap stocks.

Imagine two cafés for sale. One is a long-established shop with steady, predictable takings. The other is a new place with queues out of the door that is opening a second and third branch. Buyers will pay more for the new café, relative to what it earns today, because they expect it to earn much more in a few years.

A growth stock is the busy new café. Its price reflects hopes for the future more than results so far. If the branches open on time and fill up, the high price looks like a bargain in hindsight. If the queues fade, buyers who paid for the future can lose a lot, because the price was resting on expectations that did not come true.

There is no single official test. Analysts and index providers look at measures such as:

• Past growth in sales and earnings per share (EPS), often over three to five years.
• Forecast earnings growth, as reflected in a high forward P/E ratio relative to the market.
• Valuation ratios. A high price-to-earnings ratio or price-to-book ratio signals that investors expect strong growth.
• Reinvestment. Heavy spending on research, new products or expansion, and a low dividend payout.

Index providers turn these into formal rules. S&P Dow Jones Indices has long scored companies for its growth and value indexes using three growth factors (three-year change in earnings per share relative to price, three-year sales-per-share growth and 12-month price momentum) against three value factors, and it announced revisions to those factors in October 2026. FTSE Russell's Russell growth indexes rank companies on book-to-price, forecast medium-term earnings growth and historical sales growth. Morningstar's style box places stocks and funds on a value–blend–growth scale. Because the methods differ, the same company can count as growth in one index and blend or value in another.

A high P/E alone does not say whether a growth stock is expensive, because faster growth can justify a higher multiple. One rough adjustment is the price/earnings-to-growth (PEG) ratio:

• $\text{P/E}$ is the share price divided by earnings per share.
• $g$ is the expected annual growth rate in earnings per share, written as a whole number (20 for 20%).

For example, a company trading at a P/E of 40 with expected earnings growth of 20% a year has a PEG of $40 \div 20 = 2$. A slower company on a P/E of 15 growing at 10% has a PEG of 1.5. By this measure the first stock is more expensive for each unit of growth, even though both may still be fairly priced. The PEG depends heavily on growth forecasts, which are often wrong, so it is a screening tool rather than a complete valuation.

Much of a growth company's value lies in profits expected many years ahead. When those future profits are discounted back to today, a higher discount rate shrinks them sharply. As a result, growth stocks tend to rise when interest rates fall and fall when rates rise. Growth stocks led US markets through much of the 2010s, an era of very low rates linked to the zero interest-rate policy, and then fell steeply in 2022 when central banks raised rates quickly to fight inflation.

Growth stocks usually carry higher volatility and a higher beta than the overall market, so they tend to fall further in a sell-off. Because their price depends on future expectations, a single disappointing quarter can trigger a large drop. Periods of enthusiasm can also inflate prices far beyond any reasonable forecast: the late-1990s technology boom, centred on the Nasdaq, ended in a crash in 2000–2002 in which many popular growth companies lost most of their value or failed.

Research by Eugene Fama and Kenneth French in the early 1990s found that, over long periods of US history, cheap value stocks had on average outperformed expensive growth stocks, a pattern known as the value premium. The pattern has not held in every decade; growth stocks outperformed value for much of the period after 2008. Many investors therefore hold both styles and rely on diversification rather than betting on one.
