Title
In Pursuit of Samuelson: Studies of Commodity Volatilities and Correlations
Abstract
Empirical analysis of price returns is an essential component in the valuation methods in any asset class. Energy commodities present unique challenges: seasonality and inventory are crucial for covariance structure; forward price volatility increases dramatically while approaching contract’s expiration: the famous Samuelson effect; liquidity in commodity futures and options liquidity is concentrated at short tenors.
This fact makes the term structure of volatility and correlations very important in pricing and hedging decisions. In this presentation, I give the results of my work with NYU students devoted to this subject. We will follow three goals:
- Parameterization of Samuelson effect and the calibration procedures for commodities futures, including seasonal commodities as gas and power.
- Samuelson effect for commodity correlations, parameterizing calendar correlations.
- Contrast between the traditional Black and its long-ago predecessor Bachelier model in view of recent dramatic events in oil markets in Spring 2020.
