## Why Analyze a Stock?

Before investing your hard-earned money, you need to answer these questions:

1. **Is the company profitable?** - Fundamental analysis
2. **Is the stock undervalued or overvalued?** - Valuation ratios
3. **What is the risk level?** - Volatility and correlations
4. **Is the momentum favorable?** - Technical analysis

---

## Part 1: Fundamental Analysis

Fundamental analysis involves studying the **financial fundamentals** of the company.

### Essential Metrics

#### 1. Revenue
This is the total amount of sales. Consistent growth is a good sign.

**What to watch:**
- YoY (Year-over-Year) growth > 10% = Excellent
- Stable growth 5-10% = Healthy
- Stagnation or decline = Warning signal

#### 2. Net Income
The money left after all expenses. This is the true profit.

**What to watch:**
- Net margin > 15% = Very profitable company
- Net margin 5-15% = Average
- Net margin < 5% = Fragile

#### 3. P/E Ratio (Price-to-Earnings)
The **most commonly used ratio** to evaluate if a stock is expensive or not.

```
P/E = Stock Price / Earnings Per Share (EPS)
```

| P/E | Interpretation |
|-----|----------------|
| < 15 | Potentially undervalued |
| 15-25 | Normal valuation |
| 25-40 | Growth expected |
| > 40 | Very expensive or hyper-growth |

#### 4. P/B Ratio (Price-to-Book)
Compares the stock price to the company's book value.

```
P/B = Stock Price / Book Value Per Share
```

- P/B < 1: Stock worth less than company assets (opportunity or value trap?)
- P/B > 3: High valuation of intangible assets (brand, tech, IP)

#### 5. Dividend Yield
The annual return in dividends.

```
Dividend Yield = Annual Dividend / Stock Price × 100
```

**Strategies:**
- Value investor: > 3% with stable growth
- Growth investor: 0-1% (profit reinvestment)

---

## Part 2: Technical Analysis

Technical analysis studies **charts and price patterns** to anticipate movements.

### Key Indicators

#### 1. Moving Averages (MA)
- **50-day MA**: Short-term trend
- **200-day MA**: Long-term trend
- **Golden Cross**: 50 MA crosses 200 MA upward = Bullish signal
- **Death Cross**: 50 MA crosses 200 MA downward = Bearish signal

#### 2. RSI (Relative Strength Index)
Measures the speed and magnitude of price movements.

| RSI | Signal |
|-----|--------|
| > 70 | Overbought - Possible correction |
| 30-70 | Neutral zone |
| < 30 | Oversold - Possible bounce |

#### 3. Volume
Volume confirms or invalidates a price movement.

- **Price up + Volume up** = Validated movement
- **Price up + Volume down** = Fragile movement
- **Price down + Volume up** = Strong selling pressure

## Part 3: Evaluating Risk

### Volatility

Volatility measures the amplitude of price variations.

**Classification:**
- Annualized volatility < 20%: Low risk
- Volatility 20-40%: Moderate risk
- Volatility > 40%: High risk

**Learn more**: [Volatility and Beta: Measuring Risk](https://portfolio-terminal.com/blog/volatility-beta-risk)

### Beta

Beta measures a stock's sensitivity relative to the market.

| Beta | Behavior |
|------|----------|
| < 0.8 | Less volatile than market |
| 0.8-1.2 | Follows the market |
| > 1.2 | More volatile than market |

**Concrete examples:**
- [Apple (AAPL)](https://portfolio-terminal.com/analyse/aapl): Beta ~1.2 - Follows market with slight amplification
- [Johnson & Johnson (JNJ)](https://portfolio-terminal.com/analyse/jnj): Beta ~0.6 - Defensive
- [Tesla (TSLA)](https://portfolio-terminal.com/analyse/tsla): Beta ~2.0 - Very volatile

## Part 4: Sector Comparison

Always compare a stock to its peers in the same sector.

### Benchmarks by Sector

| Sector | Avg P/E | Div Yield | Volatility |
|--------|---------|-----------|------------|
| Tech | 25-35 | 0.5-1% | 25-40% |
| Finance | 12-18 | 2-4% | 20-30% |
| Healthcare | 18-25 | 1-2% | 15-25% |
| Energy | 10-15 | 3-5% | 25-35% |
| Consumer | 20-28 | 1-3% | 15-25% |

## Questions and answers

**What is the single most important metric to analyze a stock?**

Free cash flow is one of the most reliable metrics because it reflects real cash a company generates after reinvestment.

**How do I know if a stock is overvalued?**

Compare valuation ratios like P/E and FCF yield to sector peers, and check if growth justifies the premium.

**What is a good ROIC for a quality business?**

A ROIC consistently above 10–15% is generally considered strong, especially if it exceeds the company’s cost of capital.

**Should I use technical analysis or fundamentals?**

Use fundamentals to select quality businesses and valuation, then technical analysis to optimize entry points and risk.
