(Examples: Nvidia, Apple, Microsoft, Amazon, Meta, Tesla, and Alphabet)

Analyzing a stock professionally involves combining fundamental analysis, technical analysis, sector evaluation, and risk management criteria. This guide outlines a complete method applicable to any stock.

1. Understand the Business and Its Competitive Advantage

Before reviewing numbers, you need to understand what the company does and why it might continue growing.

Key Questions

  • What is its business model? (hardware, software, cloud services, advertising…)
  • Does it have durable competitive advantages (moats)?
  • Does it depend on a single product, or is it diversified?
  • How exactly does the company generate revenue?

Examples

  • Nvidia → Dominates GPU markets for AI, gaming, and data centers.
  • Apple → Closed ecosystem, strong customer loyalty, recurring service revenue.
  • Microsoft → Software, Azure, AI, and enterprise productivity tools.
  • Meta → Advertising + growth in AI and VR.
  • Tesla → EV leader but faces increasing competition.
  • Amazon → E-commerce + AWS (its most profitable segment).
  • Alphabet (Google) → Search, ads, YouTube, AI, and cloud.

2. Review Financial Statements (Fundamental Analysis)

Here you analyze key metrics to understand whether the company is solid, growing, and profitable.

2.1 Revenue (Top Line)

Measures growth.
Question: Are revenues increasing consistently?

Example:
Nvidia and Microsoft have accelerated revenue growth driven by AI.

2.2 Operating Margin and Net Margin

These measure efficiency.

Professional Reference Levels - Net margin > 15% → excellent for tech companies.
- Higher operating margins → better efficiency.

Example:
Meta significantly improved margins after cost reductions in 2023–2024.

2.3 Free Cash Flow (FCF)

More important than net income.
Question: Does the company generate real cash?

Example:
Apple and Microsoft generate large free cash flows used for buybacks and dividends.

2.4 Debt Metrics

Review: - Debt / Equity
- Debt / EBITDA

Examples:
- Tesla now maintains healthy debt levels.
- Alphabet has very low debt relative to its size.

2.5 Valuation

Determines whether the stock is expensive or undervalued.

Main Valuation Multiples - P/E (Price / Earnings)
- P/S (Price / Sales)
- P/FCF
- EV/EBITDA

Examples - Nvidia often trades at a high P/E due to high expectations.
- Apple trades at a higher P/E relative to its growth rate.
- Alphabet is usually cheaper relative to its cash flow.

3. Analyze the Sector and Macroeconomy

Economic and sector-specific conditions impact performance.

Key Factors

  • Interest rates (strong influence on tech valuations)
  • Competitive landscape
  • Regulatory pressures (especially for Meta and Alphabet)
  • Tech trends (AI, cloud, semiconductors, EVs, digital ads)

Examples - Nvidia benefits from the AI boom.
- Tesla faces competition from Chinese manufacturers like BYD.
- Amazon and Microsoft compete intensely in cloud computing.

4. Technical Analysis (Timing Entry and Exit)

Technical analysis helps determine when to enter or exit a position.

Useful Indicators

  • Trend: 50-day and 200-day moving averages
  • Support and resistance levels
  • RSI (overbought/oversold)
  • Volume
  • Price structure

Examples

  • Nvidia often trends strongly upward; pullbacks to the 50-day MA can be good entries.
  • Tesla is volatile; timing is crucial.
  • Apple and Microsoft follow long-term trends more consistently.

5. Risk Evaluation

Professional analysis always includes risk assessment.

Main Risks

  • Product dependence (Apple → iPhone)
  • Strong competition (Tesla vs BYD, Nvidia vs AMD)
  • Regulation (Meta, Alphabet)
  • Economic cycles
  • Overvaluation risk (Nvidia, Tesla)

6. Company Comparison (Benchmarking)

Compare companies with similar business models:

  • Nvidia vs AMD
  • Apple vs Samsung
  • Microsoft vs Amazon vs Google (cloud services)
  • Meta vs Google (digital advertising)

This helps identify the strongest option in each segment.

Company Summary Table

Company Main Strength Main Risks
Nvidia AI leadership, GPUs, high margins High valuation
Apple Ecosystem, cash flow, loyalty Heavy dependence on iPhone
Microsoft Azure, AI, Office suite Cloud competition
Amazon AWS, logistics Low e-commerce margins
Meta Advertising, efficiency, AI Regulation, saturation
Tesla Strong brand, EV technology Competition, volatility
Alphabet Search, YouTube, AI Antitrust regulation
