Explanation

INV 201: A delta hedge leaves other risks to assess

Delta describes a local first-order sensitivity. Nonlinearity, volatility changes, discrete rebalancing, basis differences and transaction costs can remain after a delta hedge.

Original practice scenario

An original option position is delta-neutral at inception. After a large market move its delta changes, and a volatility change also affects value. Identify gamma and volatility sensitivity before claiming the hedge eliminates risk. State the rebalancing assumptions and a practical limitation.

Study check

Write the assumptions, the decision being supported and one limitation. Use the current course syllabus for the required terminology and scope; this introductory guide is not a complete course summary.

Explanation

INV 201: Risk-neutral pricing and real-world projection answer different questions

A pricing measure and an experience-projection measure have different purposes. A no-arbitrage value should not be interpreted automatically as a real-world expected payoff or forecast.

Original practice scenario

For an original derivative example, label the measure used to value the payoff and the assumptions used to project realised returns. Explain where discounting enters. Keep the intended valuation and forecasting tasks separate rather than swapping probabilities to obtain a preferred number.
