Executive Summary
3-Sentence Investment Thesis
East West Bancorp is the largest Asian-American focused bank in the United States, uniquely positioned to serve the cross-border commercial banking needs between the US and Greater China. With a 16% ROE, 14.3% CET1 ratio, and Li Lu's 8.5% Himalaya Capital stake as superinvestor validation, EWBC represents a rare "quality bank" trading at 1.77x book value with 9% expected growth. The market may be undervaluing EWBC's sustainable competitive advantages in niche Asian-American banking while overweighting China trade war headline risk.

Investment Decision
| Recommendation | Entry Price | Position Size |
|---|---|---|
| WAIT | Accumulate <$105, Strong Buy <$95 | 2-4% portfolio |
Rationale: Exceptional franchise quality, but current price offers limited margin of safety. The stock has rallied 45% from 2024 lows. Wait for a pullback driven by macro headlines (China trade tensions, CRE concerns) that would create opportunity in an otherwise excellent bank.

Phase 1: Risk Analysis (Munger Inversion)
"What Would Destroy This Investment?"
Top 10 Risks Ranked by Expected Loss
| # | Risk Event | P(Event) | Impact | Expected Loss | Mitigant |
|---|---|---|---|---|---|
| 1 | US-China trade war escalation | 25% | -30% | -7.5% | Revenue 95%+ US-based; export finance <5% |
| 2 | Commercial Real Estate cycle (office) | 35% | -20% | -7.0% | CRE 28% of loans; office only 2.4%; 3.1% reserves |
| 3 | Interest rate volatility | 40% | -15% | -6.0% | Asset-sensitive but hedged; 50% deposit beta |
| 4 | Regulatory/Compliance risk | 15% | -25% | -3.8% | Long history of compliance; no consent orders |
| 5 | Credit cycle deterioration | 30% | -12% | -3.6% | NCOs 26bps; 1.31% reserves; conservative LTV |
| 6 | Competition from big banks | 20% | -15% | -3.0% | Niche too small for JPM/BAC focus |
| 7 | Key man risk (Dominic Ng) | 10% | -20% | -2.0% | Deep management team; CFO/CRO experienced |
| 8 | Deposit flight/concentration | 15% | -12% | -1.8% | Granular deposit base; 24% DDA |
| 9 | California earthquake | 5% | -20% | -1.0% | HQ in Pasadena; geographic diversification |
| 10 | China domestic banking exposure | 5% | -15% | -0.8% | No direct China bank subsidiaries |
Total Expected Downside: -36.5% (probability-weighted)
Tail Risk Scenario (Non-Additive)
Scenario: Full US-China Decoupling + CRE Crisis + Credit Cycle
- If all three occur simultaneously: -50% to -60% drawdown possible
- Probability: ~5%
- Mitigants: CET1 14.3% provides capital cushion; tangible book ~$65/share floor
Permanent Capital Loss Scenario
What would cause permanent impairment?
- Massive loan fraud - Low probability given conservative culture
- Regulatory action/consent order - No history of issues
- Complete US-China trade halt - Would still have 95%+ domestic business
- Bank run - $5.3B cash, 24% cash+securities = high liquidity
Assessment: Low risk of permanent capital loss

Catalysts
Positive Catalysts
- US-China trade normalization - Would remove headline overhang
- Interest rate cuts - Lower deposit costs, NIM expansion
- CRE concerns abate - Office loan maturities pass without issue
- Wealth management growth - 20%+ annual fee income growth
- Buyback acceleration - $329M authorization available

Negative Catalysts

Klarman Lens
Downside Case
What if everything goes wrong?
- EPS falls 30% to ~$6.60 (2020 levels)
- P/E compresses to 9x (sector average)
- Stock price: $60 (47% downside)
- Tangible book value: $65 (floor)
Probability: 15%
Why Market May Be Wrong
Bull case for mispricing:
- Headline risk overstated: China trade tensions don't impact 95%+ domestic business
- CRE fears overdone: Office only 2.4% of loans with 3.1% reserves
- Regional bank taint: SVB/FRC contagion unfair to well-run bank
- Li Lu underfollowed: Market doesn't appreciate superinvestor validation
- Niche moat undervalued: Unique franchise in Asian-American banking
Steelmanning the Bears
Why bears might be right:
- Overearning on NIM: 2022-2024 benefited from rate environment
- CRE risks underestimated: Office exposure could worsen
- China exposure hidden: Cross-border business more significant than disclosed
- Management succession risk: Dominic Ng (70+) eventual retirement
- Multiple compression: Regional banks structurally deserve lower multiples

| Accumulate | $95-$105 | Gradual position building |
| Hold | $105-$135 | Current range |
| Trim | >$135 (P/E 14x+) | Take profits |
Why WAIT (Not BUY Now)?
