How to read the analysis

Fundamentals basics

The analysis groups the numbers into four questions: how profitable, how fairly priced, how strong the business and what could go wrong.

  • Pasting real figures from the company’s annual report gives far better results than a name alone.
  • Check two or three of the ratios yourself with a calculator. It is the fastest way to learn them.
  • Compare ratios with similar companies, not with a fixed rule.
  • Treat valuation comments as clues for research, not price targets.

Quick answer

How do you do fundamental analysis of a stock?

Fundamental analysis judges a company by its business and its numbers. Read the annual report (Form 10-K) and work through four questions: Is it growing? (revenue trend), Is it profitable? (margins and return on equity), Is it financially strong? (debt and cash flow) and Is the price reasonable? (ratios such as P/E).1 In Apple’s historical FY2025 example below, revenue grew 6.43% and net margin was 26.92%. A current P/E needs a separately verified share price.

Revenue growth6.43%
Net margin26.92%
Debt to equity1.34

Key takeaways
  • Four questions. Growth, profit, strength, price.
  • Margins. Gross, operating, net: profit per dollar of sales.
  • ROE. Net income ÷ average equity; specify the period.
  • Debt to equity. Debt ÷ equity.
  • Free cash flow. Operating cash − capital spending.
  • P/E. Price ÷ earnings per share.

Part 1 of 3 · The key ratios

How should I read the fundamental analysis?

A handful of ratios answer most of the questions. Here they are, worked out from Apple’s historical FY2025 filing.

Apple FY2025, ratio by ratio

Apple FY2025 ratios — USD millions, except EPS
RatioHow it is calculatedHistorical result
Revenue growth(This year − last year) ÷ last year(416,161 − 391,035) ÷ 391,035 = 6.43%
Gross marginGross profit ÷ revenue195,201 ÷ 416,161 = 46.91%
Operating marginOperating income ÷ revenue133,050 ÷ 416,161 = 31.97%
Net marginNet income ÷ revenue112,010 ÷ 416,161 = 26.92%
Return on equityNet income ÷ average beginning/end equity112,010 ÷ [(56,950 + 73,733) ÷ 2] = 171.42%
Debt to equityInterest-bearing debt ÷ ending equity(7,979 + 12,350 + 78,328) ÷ 73,733 = 1.34
Free cash flowCash from operations − capital spending111,482 − 12,715 = $98,767M
P/EShare price ÷ earnings per shareA matching dated share price ÷ FY2025 diluted EPS of $7.46; no price is assumed

Historical filing figures. Debt excludes leases; free cash flow is operating cash less PP&E payments. P/E needs a separately checked price. 4

What do these figures tell us?

Revenue grew, but free cash flow was below net income. High ROE can reflect a small equity base and share repurchases; it does not by itself establish business quality. Read cash flow, debt definitions and risks together. No share price is supplied, so this example does not claim a current P/E or valuation.

3

Is a P/E of 30 high?

Only in comparison. P/E is share price divided by earnings per share. Compare the same earnings basis with similar companies and the company’s own history.5 Apple reported diluted EPS of $7.46 for FY2025. At a hypothetical P/E of 30, that historical EPS implies $223.80 (30 × $7.46). This is arithmetic, not a current quote, price target or estimate of fair value.

The reciprocal of 30 is an earnings yield of about 3.33%; at a P/E of 15 it is about 6.67%. This is an accounting ratio, not a cash return promised to shareholders. Growth, risk and the quality of earnings all matter.

Keep the comparison consistent

Apple’s $7.46 is historical diluted EPS. Do not compare a P/E using that figure with another business’s forward or adjusted P/E without identifying the difference. A current P/E also needs a verified share price from the same stated date.

The rule

Growth, profit, strength, price. Work through them in that order.

Part 2 of 3 · Getting good input

What input gives the best fundamental analysis?

The AI can only analyze what you give it. A name alone gets general comments; real figures get real analysis.

4

Where to find the numbers

  1. Search the company on SEC EDGAR and open its latest Form 10-K.
  2. Copy revenue, gross profit, operating income and net income from the income statement, for two years.
  3. Copy total debt and shareholders’ equity from the balance sheet.
  4. Copy cash from operations and capital spending from the cash flow statement.
  5. Paste them into the tool with your question.
5

What should I ask?

  • “Is this company financially healthy?”
  • “What are the biggest risks in these numbers?”
  • “How does its profitability compare with typical companies in its industry?”
  • “What would need to happen for the current price to make sense?”
6

Should I use annual or quarterly numbers?

Start with annual figures from the 10-K, which include audited financial statements.4 Quarterly 10-Q reports are filed for the first three fiscal quarters and are unaudited, so they are more current but less checked.6

When the annual report is many months old, build a trailing twelve months figure by adding the four most recent quarters. Because there is no separate fourth-quarter 10-Q, derive that quarter from the full year less the first nine months, using the same accounting basis. Compare like periods and check whether the company has restated its figures.

Label every figure with its period and units, for example “Apple revenue, FY2025: $416,161 million.” Mixing a quarter with a year can distort growth and margins; a P/E requires an annual earnings basis. Use average equity when calculating the ROE shown on this page.

The rule

Better numbers in, better analysis out.

Part 3 of 3 · What it can get wrong

What can the AI fundamental analysis get wrong?

The analysis is a learning aid. Numbers and judgments need checking.

7

What are the limits?

  • No live data. Without pasted figures, it relies on general knowledge, which can be out of date.
  • Math and facts can be wrong. Recheck key ratios yourself.
  • No price targets or buy and sell recommendations.
  • Daily limits. Free analyses are limited each day.

What if net income includes a one-time gain or charge?

One-time gains and charges can distort comparisons based on reported profit. An AI working only from totals may miss them, so check the notes and management’s discussion rather than treating every change as an operating trend.

A real Apple tax charge

Apple’s FY2024 Form 10-K describes a one-time $10.2 billion net income-tax charge related to the State Aid decision. This reduced reported profit and complicates a comparison with FY2025. It is a charge, not a recurring fall in sales.7

Keep reported and adjusted figures separate, state what you removed and why, and reconcile any adjustment to the filing. Comparing net income with cash from operations can help, but working capital and tax timing can also create legitimate differences.

The rule

Let the AI explain. Check the math yourself.

Mistakes to avoid

Three mistakes to avoid, and what to do instead

Asking without the numbers

With only a ticker the AI works from memory and can be out of date. Paste revenue, profit, debt and cash from the latest filing for a real answer.

Stopping at one ratio

A low P/E can mean cheap or can mean trouble ahead. Read growth, margins and debt together before you decide what the number says.

Skipping the risk factors

The filing lists what could go wrong, in the company’s own words. It is the most honest section and the least read.

Three quick questions and one why

0 of 3 answered

1. Apple FY2025 revenue was $416,161M and net income was $112,010M. About what was its net margin?

Answer: B, 26.92%.112,010 ÷ 416,161 × 100 = 26.92%.

2. Apple’s defined FY2025 debt was $98,657M and ending equity was $73,733M. About what was debt to equity?

Answer: A, 1.34.98,657 ÷ 73,733 = 1.34; this definition excludes leases.

3. Where are a company’s official yearly figures?

Answer: A, its Form 10-K on SEC EDGAR.Public companies file audited annual reports with the SEC.
Why: why compare free cash flow with net income?

Compare cash and accounting measures over several periods. Working capital, taxes and capital spending can create legitimate differences. Apple FY2025 free cash flow was below net income; that gap calls for explanation, not a conclusion that earnings are unreal.

Common questions

AI Fundamental Analysis Tool FAQ

What is fundamental analysis of a stock?

Fundamental analysis judges a company by its business and its financial results rather than its price chart. You read the annual report and ask whether revenue is growing, whether the company is profitable, whether its finances are strong and whether the share price is reasonable for what you get. Ratios such as net margin, return on equity, debt to equity and P/E turn those questions into numbers you can compare across years and with similar companies.

What are the most important financial ratios for beginners?

Start with revenue growth, net margin, return on equity, debt to equity and P/E, then compare free cash flow with profit. Apple’s historical FY2025 example here has 6.43% revenue growth, 26.92% net margin, 171.42% ROE using average equity, and debt to equity of 1.34 under the debt definition stated beside the table. Its diluted EPS was $7.46; a current P/E also requires a verified share price. Compare definitions, periods and similar businesses.

How do you calculate the P/E ratio?

Divide the share price by annual earnings per share, identifying whether EPS is basic, diluted, reported, adjusted or forward. Apple reported FY2025 diluted EPS of $7.46. A purely hypothetical $223.80 share price divided by $7.46 gives 30. That illustrates the ratio; it is not a current Apple quote or a valuation recommendation. Compare like earnings bases and explain any adjustments.

Is the AI fundamental analysis tool free?

Yes. The tool is free with a daily limit on analyses, and no account is needed. You enter a company name or ticker, optionally paste figures or upload a TXT or CSV file up to 5MB, add a question and press Analyze Fundamentals. Everything you enter goes to an AI model through StockEducation’s server, which returns an explanation of ratios, valuation, business quality and risks.

Do I need to paste financial numbers into the tool?

No, but the results are far better when you do. The tool does not fetch live prices or filings, so a company name alone gets general comments based on what the AI model already knows, which can be out of date. Pasting revenue, profit, debt, equity and cash flow figures from the latest 10-K lets it calculate real ratios. Label each figure with its year so annual and quarterly numbers do not get mixed.

Does a low P/E mean a stock is cheap?

Not necessarily, and this is one of the most common misconceptions. A low P/E can signal that investors expect profits to shrink, or that last year’s earnings were inflated by a one time gain. A high P/E can be reasonable for a company growing quickly. The ratio tells you what the market is paying today, so ask why the number is low or high before treating it as a bargain.

Does the tool give price targets or buy recommendations?

No. It explains what a company’s numbers say about growth, profitability, financial strength and valuation, and it points out risks worth researching. It does not set price targets or tell you to buy or sell, and its math can contain errors. Recheck two or three ratios yourself with a calculator. To turn the figures into an estimate of value, try the DCF calculator linked on this page.

What is the difference between fundamental and technical analysis?

Fundamental analysis studies the business: its revenue, profits, debt, cash flow and valuation, mostly from the 10-K and 10-Q. Technical analysis studies price charts and trading volume to look for patterns and trends. A fundamental investor asks what the company is worth; a technical trader asks where the price is likely to move next. Many long term investors rely mainly on fundamentals.
