Market Making Correlation Interview Questions
Market making correlation interview questions for updating related markets, hedging exposures, and avoiding independence mistakes.
Candidates in multi-asset or related-event market-making games.
Correlation links markets
When two markets are related, information in one market can change fair value or risk in the other.
Do not assume independence
If two events are correlated, multiplying probabilities or treating quotes separately can produce bad markets.
Concrete example
If two event contracts depend on the same underlying driver, a signal that raises one probability may also raise the other.
Hedging depends on relationship strength
A related market can hedge some exposure, but weak or unstable correlation leaves residual risk.
Update cautiously
Correlation does not mean one-for-one movement. State the direction and rough strength of the relationship.
Common mistakes
Candidates often treat related markets as either identical or independent. Most interview cases live between those extremes.
