Gamma Market Making Interview Intuition
Gamma market making interview intuition for convexity risk, changing delta, large moves, and option quote protection.
Candidates who need high-level option risk language.
Gamma is changing directional exposure
At interview-intuition level, gamma means the directional exposure of an option can change as the underlying moves.
Convexity matters in large moves
Large underlying moves can change option value and hedge needs more sharply than a simple linear position.
Concrete example
A position that seems lightly directional near one price can become much more directional after the underlying moves closer to a payoff threshold.
Quote wider when risk changes fast
If exposure can change quickly, a market maker may need wider quotes or smaller size to avoid stale risk.
Connect to volatility
Higher expected movement can make convexity more important because the underlying is more likely to move into states where exposure changes.
Common mistakes
Candidates often use greek terms without explanation. In interviews, plain-language risk intuition is more useful than jargon.
