What is fundamental analysis?

What it looks at

Fundamental analysis starts from a simple idea: behind every stock there is a business, and over the long run the price tends to reflect what that business earns. To estimate it, you look at three layers:

• The company: revenue, earnings, cash flow, debt, and margins, all taken from its quarterly and annual financial statements.
• The industry: competition, competitive advantage, regulation, and where the sector is headed.
• The economy: interest rates, inflation, employment, and growth, which affect every company at once.

An example with numbers

One of the most widely used measures is the price-to-earnings ratio (P/E): the stock price divided by earnings (profit) per share over the last twelve months.

Hypothetical example: a company trades at $50 and earned $2.50 per share. Its P/E is 50 ÷ 2.50 = 20. You are paying $20 for every $1 of annual earnings. If comparable companies trade at a P/E of 25, this one looks cheaper.

That word “looks” matters. A low P/E can point to an opportunity, or to a business with problems the market is already pricing in. One number on its own is not enough: you also need to check the sales trend, the debt, and the outlook.

Fundamental vs. technical: what vs. when

Fundamental analysis answers what has value. Technical analysis answers when, because it studies how price behaves. A long-term investor can lean almost entirely on fundamentals. A trader who holds positions for days or weeks, as in swing trading, usually relies on technicals to get in and out and uses fundamentals as a filter.

In practice, a technical trader doesn’t ignore fundamentals: they check the date of the next earnings report, because on that day the price can gap open right past their stop.

What a trader checks before trading

Even if you trade from charts, it pays to keep three fundamental items handy:

• Earnings calendar: the date of the company’s next quarterly report.
• Expectations: the market doesn’t react to the number itself, but to the gap between what was reported and what was expected, and to what the company forecasts for the coming quarters.
• Economic calendar: Federal Reserve rate decisions, inflation, and jobs data, which move the whole market on the same day.

Hypothetical example: a company reports earnings above expectations but cuts its sales forecast for the year. The stock may fall the next day, because the price had already priced in a good quarter and what changed was the future. That’s why “good news” doesn’t always mean the price will go up.

The limitation

The market can take months or years to recognize the value you found, and a “cheap” stock can keep falling in the meantime. On top of that, financial statements look backward while the price looks forward. That’s why it makes sense to decide in advance how much you are willing to lose if your thesis doesn’t play out in time.
