Fundamental Analysis of a Stock: Complete Method and Key Ratios

Introduction to Fundamental Analysis of a Stock

Fundamental analysis aims to evaluate the intrinsic value of a stock based on the company’s financial and economic data. Unlike technical analysis, it relies on quantitative and qualitative indicators to determine whether a stock is undervalued or overvalued by the market. This method is essential for French investors seeking to make informed decisions, especially regarding international stocks such as Apple or LVMH.

Key Ratios in Fundamental Analysis

Price-to-Earnings Ratio (P/E)

The P/E ratio is the relationship between the stock price and the earnings per share (EPS). Formally:

P/E = Stock Price / EPS

It indicates how much investors are willing to pay for one euro of earnings. A high P/E can signal anticipated growth but also overvaluation. A low P/E may indicate undervaluation or difficulties.

Example: As of 12/31/2023, Apple shows a P/E of 27.6 (Bloomberg), while LVMH has a P/E of 28.1 (Bloomberg). These values are relatively close, reflecting similar growth expectations in their respective markets.

Price-to-Book Ratio (P/B)

The P/B ratio compares market capitalization to the book value of equity:

P/B = Stock Price / Book Value per Share

It measures how much the market values the company’s net assets. A P/B close to 1 indicates the stock is valued at its book value; a P/B above 1 suggests valuation beyond book value, often justified by profitability or prospects.

As of 12/31/2023, Apple has a P/B of 36.8 (Bloomberg), reflecting its significant intangible assets (brand, innovation), while LVMH has a P/B of 5.7 (Bloomberg), high but more moderate, consistent with its luxury sector.

EV/EBITDA Ratio

EV/EBITDA compares enterprise value (EV) to EBITDA (earnings before interest, taxes, depreciation, and amortization):

EV = Market Capitalization + Net Debt

This ratio is less affected by financial structure than the P/E and is useful for comparing companies with different debt levels.

As of 12/31/2023, Apple’s EV/EBITDA is 19.4, while LVMH’s is 21.2 (Bloomberg). These figures indicate the market values LVMH’s revenue before non-operational charges slightly higher.

Return on Equity (ROE)

ROE measures the profitability of shareholders’ equity:

ROE = Net Income / Shareholders’ Equity

It indicates the company’s efficiency in generating profit with shareholders’ money. A high ROE generally signals strong operational performance.

For the 2023 fiscal year, Apple reports an ROE of 47.8% and LVMH an ROE of 23.4% (Bloomberg). Apple’s ROE is exceptionally high, reflecting its strong profitability and low equity base.

How to Read an Annual Report

The annual report is the primary source of financial information. Key sections to analyze are:

  • Income Statement: To study profitability, revenue growth, and margins.
  • Balance Sheet: To understand financial structure, equity, and debt.
  • Cash Flow Statement: To verify the company’s ability to generate cash.
  • Management Discussion and Analysis: For outlook, risks, and strategy.

For example, Apple’s 2023 annual report (available on investor.apple.com) highlights 11% revenue growth to USD 420 billion and a stable gross margin of 43%. LVMH’s report (available on lvmh.fr) shows 15% revenue growth to EUR 90 billion with an operating margin of 24%.

Numerical Example: Apple vs LVMH

Net Debt (Billion)1090.72023 Annual Reports
EV/EBITDA19.421.2Bloomberg
ROE47.8 %23.4 %Bloomberg

These figures illustrate two global giants with different financial profiles: Apple is highly profitable with a high ROE and significant intangible assets valued by the market (very high P/B). LVMH, in the luxury sector, shows solid growth and a high but more "classic" valuation.

Estimating Intrinsic Value via a Simplified DCF Method

The Discounted Cash Flow (DCF) method estimates the present value of future cash flows available to shareholders, discounted at a rate reflecting risk. To simplify:

  • Estimate current free cash flows (FCF)
  • Project an average annual growth rate
  • Apply a discount rate (cost of capital)
  • Calculate the terminal value

Apple (in billion USD):

  • FCF 2023: 100 Bn (annual report)
  • Projected FCF growth: 5% per year
  • Discount rate: 8% (weighted average cost of capital WACC)
  • Terminal value with perpetual growth of 2%

Terminal value formula: Vt = FCFn × (1 + g) / (r - g)

At year 5: FCF5 = 100 × 1.05⁔ ≈ 127.6 Bn

Terminal value = 127.6 × 1.02 / (0.08 - 0.02) = 2170 Bn USD

Discounting the cash flows over 5 years plus terminal value yields an estimated enterprise value around 1800-1900 Bn USD, consistent with the market capitalization (~1800 Bn USD) (Bloomberg).

LVMH (in billion EUR):

  • FCF 2023: 15 Bn (annual report)
  • Projected FCF growth: 6% per year
  • Discount rate: 7.5% (WACC)
  • Perpetual growth: 2%

FCF5 = 15 × 1.06⁔ ≈ 20.1 Bn

Terminal value = 20.1 × 1.02 / (0.075 - 0.02) = 374 Bn EUR

Discounted firm value estimated around 310-320 Bn EUR, in line with the market capitalization of 320 Bn EUR (Bloomberg).

Conclusion and Recommendations for French Investors

Comprehensive fundamental analysis, using P/E, P/B, EV/EBITDA, and ROE ratios combined with rigorous annual report review and a DCF estimate, allows assessing a stock’s real valuation. Apple and LVMH clearly illustrate two distinct sectoral approaches: technology with high profitability and valued intangible assets, versus luxury with strong growth and more tangible valuation.

For a French investor:

  • Apple remains a solid but expensive stock, whose valuation reflects future growth already priced in. The high P/E and very high P/B should encourage caution regarding timing of purchase.
  • LVMH offers a more classic valuation supported by robust growth and high margins, interesting for exposure to the luxury sector with a less volatile profile.

In summary, these analyses show that no stock is intrinsically "cheap" or "expensive" without context. The investor must combine these tools with their strategy, horizon, and risk tolerance. Using the DCF method confirms that current valuations are broadly justified, suggesting waiting for market opportunities to enter at a better price.
