Table of Contents
1. What is Quantitative Finance?
Quantitative Finance applies mathematical models, statistics, and programming to analyze financial markets, price derivatives, manage risk, and optimize portfolios.
Key areas include stochastic calculus, Monte Carlo simulations, and machine learning.
Quants develop algorithms for trading, hedging, and arbitrage, using tools like Python, R, and numerical libraries.
2. Quant Finance Interview Topics
- Core Models: Black-Scholes, binomial pricing, Greeks, VaR, CVaR.
- Math: Stochastic calculus (Ito’s lemma), PDEs, linear algebra, probability puzzles.
- Programming: Python/R/C++ coding (optimization, data structures), algorithmic trading simulations.
- Data: Time-series analysis, volatility modeling, backtesting.
- Advanced: Machine learning (predictive models), fixed-income math, exotics pricing.
- Case Studies: Portfolio optimization, hedging strategies, market impact analysis
Quant Finance Interview Questions
3.1 Negative Beta
A negative beta implies the asset moves opposite direction to the market. It’s rare but can occur with certain defensive stocks or gold.
3.2 Negative Working Capital in DCF
Some businesses, like grocery stores, receive cash from customers before paying suppliers. This negative working capital can inflate DCF valuations as the business effectively gets “free” financing.
3.3 Zero Cost of Equity
Zero Cost of Equity is theoretically possible if a company’s returns perfectly match the market’s. Practically unrealistic due to company-specific risks.
3.4 Negative Cost of Debt
Negative Cost of Debt is possible in certain economic environments with negative interest rates. Rare but can occur, particularly with government bonds in some countries.
3.5 Perpetual Growth Rate Exceeding GDP
Perpetual Growth Rate Exceeding GDP is generally considered unsustainable long-term, as a company can’t outgrow the economy forever. It may be temporarily justified for disruptive companies in growing markets.
3.6 Terminal Value Exceeding Total Value
Terminal Value Exceeding Total Value is common in high-growth companies where near-term cash flows are negative. Implies most value comes from long-term performance, which can be risky.
3.7 Negative Equity Value, Positive Stock Price
Negative Equity Value, Positive Stock Price can occur if the market expects future performance to improve dramatically or if there are valuable off-balance sheet assets not reflected in book value.
3.8 Valuation Multiple Expansion
Valuation Multiple Expansion occurs when a company’s multiple (e.g, P/E ratio) increases. Often due to improved growth prospects, reduced risk, or overall market sentiment changes
3.9 Deferred Tax Assets in Valuation
Deferred Tax Assets in Valuation represent potential future tax savings. In DCF, they’re often treated as a non-operating asset and added to the present value of future cash flows.
3.10 Off-Balance Sheet Liabilities
Off-Balance Sheet Liabilities are obligations not reported on the balance sheet, like operating leases or contingent liabilities. Must be considered in valuation as they represent a real financial commitment
3.11 Valuation of Intangible Assets
Valuation of Intangible Assets uses methods like relief from royalty or excess earnings. Crucial for knowledge-based companies where most value isn’t captured on the balance sheet.
3.12 Valuation of Zero-Revenue Companies
Valuation of Zero-Revenue Companies relies on non-financial metrics, market size estimates, and probability-weighted scenario analysis. Common in biotech, where value depends on the potential of drugs in development.
3.13 Impact of Stock-Based Compensation on Valuation
The impact of Stock-Based Compensation on Valuation significantly affects cash flows and ownership structure. Often treated as a non-cash expense in EBITDA calculations, but represents a real cost to shareholders through dilution.
3.14 Adjusting Beta for Financial Leverage
Adjusting Beta for Financial Leverage involves unlevering and re-levering beta to account for differences in capital structure between the company being valued and its comparable. Ensures fair comparison of business risk.
