About this resource
Most aspiring quants don’t struggle with equity models because they lack math.
They struggle because they can’t connect models to PnL, hedging, and real desk decisions.
- You may know:
- Black–Scholes assumptions
- Heston equations
- Local volatility formulas
- But interviews and desks ask different questions:
Why does delta hedging bleed?
Why do barriers misprice under local vol?
Why does skew dominate PnL in crashes?
Which model breaks first — and how do you detect it?
This guide is built to answer those questions.
📘 What this guide focuses on
This is not a formula-heavy textbook.
This is a model-thinking and PnL-first guide for equity desks and interviews.
- You’ll learn:
- Why equity skew is structural (not incidental)
- How volatility, skew, vanna, and jumps drive real PnL
- Why desks knowingly use “wrong” models
- How to choose models based on dominant risk — not elegance
- 🧠 Models Covered (with intuition + consequences)
- Black–Scholes — why it fails, why it still survives
- Local Volatility (Dupire) — perfect fit, broken dynamics
- Stochastic Volatility (Heston) — skew, vol-of-vol, hedging stability
- Jump Models (Merton / Bates) — earnings gaps & crash risk
- Local–Stochastic Vol (LSV) — the desk compromise model
- Each model is explained via:
- assumptions → equations → calibration → Greeks → PnL → failure modes
- 📊 What makes this guide different
- Master Equity Model Map (one-glance comparison of all models)
- Explicit PnL attribution: delta, gamma, vega, skew, vol-of-vol
- Model failure signatures (how to detect when your model is wrong)
- Real desk-style case studies (barriers, autocalls, crash regimes)
- Interview-ready language, not academic phrasing
- Clear explanation of why residual PnL ≠ trader error
- 🎯 Who this is for
- Aspiring Equity Desk Quants
- Derivatives Traders who want model intuition
- Risk / Model Validation / XVA Quants
- Candidates preparing for front-office interviews
If you already know the math but struggle to explain models like a practitioner, this guide closes that gap.
