Measuring the Impact of Transition Risk on Financial Markets: A Joint VaR‐ES Approach

Journal of Forecasting, EarlyView.
ABSTRACT Based on a joint quantile and expected shortfall semiparametric methodology, we propose a novel approach to forecasting market risk conditioned to transition risk exposure. This method allows us to forecast two climate‐related financial risk measures called CoClimateVaR$$ CoClimateVaR $$ and CoClimateES$$ CoClimateES $$, being jointly ...

Skewness Premium for Short‐Term Exposure to Squared Market Returns

Journal of Futures Markets, EarlyView.
ABSTRACT Following Kraus and Litzenberger, the skewness of stock returns is often modeled as exposure to the square of the market return. We use a trading strategy in S&P 500 options that creates exposure to the square of the S&P 500 return without affecting other characteristics of a direct index investment.
