ETF Arbitrage Quant Interview Guide
ETF arbitrage quant interview guide for ETF price, NAV, baskets, creation-redemption, premium-discount, costs, and risks.
Candidates discussing ETF market structure and relative value mechanics.
ETFs trade separately from their basket
An ETF has a market price and an underlying basket or NAV estimate. Premiums and discounts can emerge when trading frictions or demand differ.
Creation-redemption links price and basket
Authorized participants can create or redeem ETF shares under rules, helping connect ETF price to basket value. The process still has costs and constraints.
Concrete example
If an ETF trades above basket value, an arbitrage-style mechanism may involve buying the basket and creating ETF shares, but costs and execution risk matter.
Basket liquidity drives risk
Hard-to-trade constituents, stale prices, market stress, and creation-redemption constraints can make the apparent premium or discount difficult to monetize.
Common mistakes
Candidates often call ETF arbitrage risk-free. Strong answers discuss basket pricing, fees, timing, liquidity, and operational constraints.
