What fundamental analysis can and can't do

You can explain what fundamental analysis studies, what it can tell you about a company, and why it cannot tell you where the price goes next.

The business behind the price

Some people buy a share because the chart looks strong. Others buy it because the company looks strong: rising sales, healthy profits, little debt.

The second approach has a name, and it fills whole libraries. It is how many professional investors work. But it is often sold as more than it is. This lesson shows what it can tell you about a company, and the important things it cannot.

Value, not timing

Fundamental analysis studies the business behind a security to estimate what it is worth. For a share, that means:

the accounts: sales, profits, cash, debt, from the company's financial statements,
the business: its products, customers, competitors and management,
the environment: the industry and the wider economy, such as interest rates and growth.

The analyst then compares that estimated value with the price. If the price is far below the estimate, the share may be undervalued. If it is far above, it may be overvalued. The method goes back to Benjamin Graham and David Dodd, whose book "Security Analysis" appeared in 1934.

What it does well:

It shows whether a company earns money, how much cash it produces and how much it owes.
It makes companies comparable, for example by how much you pay for each dollar of profit.
It tells you what the current price assumes about the future.

What it cannot do is tell you when the price will move. A share can stay "too cheap" or "too expensive" for years.

It also competes with everyone else. The efficient market hypothesis, formalized by economist Eugene Fama in 1970, says that prices quickly reflect available information. Markets are not perfectly efficient, but the evidence is humbling: S&P's SPIVA scorecard found that 65% of active large-cap US funds trailed the S&P 500 in 2024, and over the 15 years to the end of 2024, in no fund category did a majority of active managers beat their benchmark.

Great company, high price

Take two fictional companies.

Company A grows its profits by about 20% a year. Its shares cost 50 times its yearly profit.
Company B grows its profits by about 3% a year. Its shares cost 8 times its yearly profit.

Company A is clearly the better business. But its price already assumes that the fast growth continues for years. If profits grow "only" 12% next year, that is excellent for a business, and still a disappointment for a price built on 20%. The shares can fall on good news.

Company B is a slower business, but very little is expected from it. Modest results may be enough to hold up its price.

The question fundamental analysis answers is not "Is this a good company?" but "Is this a good company at this price, given what is already expected?"

Common mistakes

Confusing a good company with a good investment. The price may already reflect all the good news. Ask what the price assumes, not only how good the business is.
Expecting a quick payoff. Value says nothing about when, or whether, the price moves toward it. Cheap shares can stay cheap for years.
Assuming you know something others don't. Published reports are read by thousands of professionals within minutes of their release.
Ignoring risk. A careful valuation can still be wrong. It does not replace position sizing and a plan for being wrong.

The takeaway

Fundamental analysis estimates what a business is worth. It cannot tell you when the price will move, and a great company can still be overpriced.

Tap the chart.

Fundamental analysis estimates value. It says nothing reliable about when a price will move toward that value, if ever.
2What does fundamental analysis mainly study?

Fundamental analysts look at the business and its environment to estimate what it is worth.
3A company grows its profits every year. Why can its shares still fall?

Prices reflect expectations. If results are good but below what was priced in, the price can fall.
4What did S&P's SPIVA scorecard find for the 15 years to the end of 2024?

Professional analysis is widespread, which is one reason known information is quickly reflected in prices.
