Market Making Hedge Cost Interview
Market making hedge cost interview guide for weighing hedge benefit, transaction cost, residual risk, and quote impact.
Candidates discussing practical risk reduction tradeoffs.
Hedges have costs
A hedge can reduce risk but cost spread, fees, slippage, or opportunity. The benefit should be compared with the cost.
Compute net benefit
In a toy prompt, compare expected loss reduction with hedge cost and any residual risk.
Concrete example
If a hedge reduces expected downside by 2 but costs 0.5, it may be worthwhile under the toy model. If it costs 3, it may not be.
Costs can change quotes
If hedging after a fill is expensive, quote wider before the fill or reduce quote size.
Residual risk matters
A cheap hedge that only weakly offsets the exposure may not solve the real risk.
Common mistakes
Candidates often discuss hedging as free. In market making, hedge cost is part of expected value.
