Prompt d'Analyse d'Investissement de Julian Robertson

❌ **Misconception 1**: "Tiger Management closed because of investment failure"
- **Reality**: Tiger's core investment thesis was correct — shorting overvalued tech stocks. The issue was **timing was too early**. Just months after closing in 2000, the Nasdaq crashed, proving Robertson right — the market's irrationality simply lasted longer than expected.

❌ **Misconception 2**: "He was just a stock trader"
- **Reality**: Robertson's greatest contribution was **talent development**. He created the "Tiger Cubs" ecosystem and is called the "godfather" of hedge funds. His proteges manage over $200 billion in assets.

❌ **Misconception 3**: "Long/short strategies are always safer than long-only"
- **Reality**: Short selling carries **unlimited loss risk**. Robertson's 1999-2000 experience demonstrates this — shorting tech stocks caused massive losses because bubbles can persist; "the market can stay irrational longer than you can stay solvent."

❌ **Misconception 4**: "Just follow Tiger Cubs' buys to make money"
- **Reality**: 13F filings have a **45-day delay**, and positions may have changed by publication. Institutional cost basis and risk tolerance are completely different from retail investors.

⚠️ **Core strategy cannot be replicated, but stock-picking philosophy is worth learning**:

**Cannot replicate**:
- ❌ **Short selling**: Ordinary investors face unlimited loss risk with shorts, requiring margin accounts and expertise
- ❌ **Leverage**: Amplifies losses alongside gains; unsuitable for individuals
- ❌ **Information advantage**: Robertson could meet with CEOs and industry experts directly; ordinary people lack such access

**Learnable concepts**:
- ✅ **Buy the best, avoid the worst**: Even without shorting, choose only the best companies in each industry
- ✅ **Management quality**: Robertson placed enormous emphasis on management integrity and competence — something anyone can assess (consistency of words and actions, reasonable compensation)
- ✅ **Concentrated portfolio**: Don't hold too many stocks (5-10 is sufficient), research each one deeply

**Practical advice**:
1. Learn Robertson's stock selection framework: industry position, management quality, valuation reasonableness
2. Invest in public funds managed by "Tiger Cubs" (like some Viking Global products) to indirectly benefit from his investment legacy
3. Follow 13F filings to track Tiger Cubs' holdings for investment inspiration

**Core Comparison**:

| Dimension | Robertson | Buffett |
|-----------|-----------|--------|
| **Strategy** | Long/short hedge (simultaneous long and short) | Long-only |
| **Vehicle** | Hedge fund (2%+20% fees) | Holding company (Berkshire) |
| **Analysis** | Fundamentals + macro overlay | Pure fundamentals, ignores macro |
| **Holding period** | Short to medium (months to 1-2 years) | Long-term/permanent |
| **Leverage** | Uses leverage to amplify returns | Rarely uses leverage |
| **Talent development** | Mentored 50+ top fund managers | Selects successors but doesn't mass-mentor |

**Biggest difference**: Robertson's shorting ability let him **profit in bear markets** (pre-1998), but also caused **losses from shorting during the tech bubble** — Tiger Management closed in 2000 precisely because of premature internet stock shorts. Buffett never shorts, avoiding such risks.

**Interesting relationship**: They respect each other. Robertson has called Buffett one of the investors he admires most.
