The Stock Market Is Not the Economy — But They’re Connected

“The stock market and the economy are two different things.” — Milton Friedman

The stock market and the economy are closely connected, but they are not the same thing. Understanding the difference helps explain why a rising stock market does not necessarily mean that households and businesses are becoming better off.

When stock markets are rising, commentators often talk as though the economy must be doing well. When markets fall sharply, the assumption is frequently reversed: a falling stock market must mean the economy is heading into trouble.

Neither conclusion necessarily follows.

The stock market and the wider economy measure different things. But that does not mean they are completely separate. In reality, they interact with one another through company profits, investment, employment, consumer spending, interest rates and expectations about the future.

The Stock Market and the Economy: What Is the Difference?

The stock market is a market for ownership claims in publicly traded companies.

When investors buy shares, they are not simply buying a piece of what a company is worth today. They are buying a claim on its expected future earnings and cash flows.

That makes share prices heavily influenced by expectations.

Investors consider questions such as whether profits will rise, whether interest rates will fall, how quickly the economy might grow, what inflation will look like and how much risk they are prepared to take.

A share price can therefore rise even when current economic conditions are weak if investors believe conditions will improve.

Equally, shares can fall while the economy is still performing reasonably well if investors begin to believe that future profits will be lower than previously expected.

The Economy Is Much Bigger

The wider economy encompasses far more than the companies represented on a stock exchange.

It includes employment, wages, household finances, consumer spending, business investment, productivity, government activity, trade and millions of private businesses.

Many of those businesses are not publicly traded at all.

This creates an obvious problem when we use a stock-market index as a shorthand for economic wellbeing.

A relatively small number of very large companies can have an enormous influence on a major stock index. Their share prices can rise substantially while smaller businesses are struggling and households are dealing with higher costs.

The market can therefore be booming without the typical household necessarily feeling that it is booming.

Markets Look Forward

One of the most important differences between financial markets and economic statistics is timing.

Economic data often tells us what has already happened. The stock market is constantly attempting to price what might happen next.

Milton Friedman placed considerable importance on the role of prices as signals. In a market economy, prices communicate information about scarcity, demand and changing conditions, helping businesses and individuals make decisions.

Share prices perform a similar signalling function in financial markets. They incorporate investors’ collective expectations about future profits, interest rates, economic growth and risk.

That does not mean markets are always right. Investors can be excessively optimistic, excessively pessimistic or simply wrong about what comes next.

But prices change because expectations change.

Investors do not wait for the economy to recover before buying shares. If they believe a recession is coming to an end, they may start buying long before official economic statistics show a clear recovery.

This is why a stock market can rise during a period when unemployment is still high or economic growth remains weak.

The opposite can happen too. An economy can appear healthy while the stock market falls because investors are becoming concerned about what lies ahead.

How Financial Markets Feed Into the Economy

The distinction between the stock market and the economy should not be taken to mean that the two operate independently.

The stock market can influence the wider economy through several channels.

One important mechanism is the wealth effect.

When share prices rise, people who own stocks, pensions or investment funds may see the value of their assets increase. Some households may respond by increasing their spending because they feel financially more secure.

That additional spending can support business revenues, employment and economic activity.

The effect can work in reverse as well. A substantial market decline can reduce household wealth and confidence, potentially causing people to postpone spending.

Stock Prices Can Also Affect Business Investment

Financial markets also influence companies themselves.

A company with a strong share price and a high market valuation may find it easier to raise equity capital. It can issue new shares to fund expansion, acquisitions, research or other investment.

A strong market can therefore improve the financial conditions facing businesses.

There is an important qualification, however. A higher share price does not automatically mean that every form of finance becomes cheaper. Companies also face bond-market conditions, interest rates, credit risk and the wider availability of finance.

Nevertheless, functioning capital markets can help businesses obtain the funds they need to invest and grow.

This is one of the ways in which financial markets and the real economy interact. The market reflects expectations about future economic activity, while financial conditions created by the market can themselves influence future investment and growth.

Why a Rising Stock Market Doesn’t Mean Everyone Is Prosperous

This is perhaps the most important point.

Ownership of financial assets is not evenly distributed.

A rising stock market can create substantial gains for people who own shares directly or through pensions and investment funds. But someone with little or no exposure to equities may see very little direct benefit from a market rally.

At the same time, that person may be dealing with rising rents, mortgage costs, food prices or other household expenses.

Looking at an index and concluding that everyone is becoming wealthier therefore tells us very little about the distribution of those gains.

A market index can tell us how investors are valuing a group of companies. It cannot, by itself, tell us how the average household is coping financially.

Why a Falling Market Doesn’t Necessarily Mean Recession

A falling stock market does not automatically mean that the economy is collapsing.

Share prices can decline because investors believe valuations have become excessive, because interest rates have changed, because expectations about future profits have deteriorated or simply because investors have become more risk-averse.

The real economy may continue expanding even while share prices fall.

Eventually, however, a prolonged market decline can have economic consequences through weaker investment, reduced household wealth and confidence, and tighter financial conditions.

Again, the important point is the relationship between the two.

The stock market can influence the economy without being a complete measure of the economy.

So Which One Should We Watch?

The answer is both — but for different reasons.

If we want to understand how investors value future corporate profits, financial markets are extremely important.

If we want to understand whether living standards are improving, we need to look at much more than share prices.

Employment, real wages, productivity, household incomes, business investment, inflation and economic output all tell us something that a stock-market index cannot tell us on its own.

The mistake is not paying attention to the stock market. The mistake is treating it as though it were the entire economy.

The Simple Lesson

Milton Friedman’s observation provides a useful starting point, but the relationship between the two is more interesting than the quotation alone suggests.

The stock market is not the economy. But the stock market is part of the economic system, and what happens in financial markets can eventually affect the real economy.

A rising market can reflect expectations of stronger economic growth. It can also create wealth and improve companies’ access to capital.

A falling market can reflect fears about the economy. It can also reduce wealth, confidence and investment.

Understanding the difference — while also understanding the connection — is much more useful than simply assuming that a rising stock index means the economy is healthy, or that a falling one means it is sick.
