This paper proposes the generalized use of fractional Brownian motion in a multifractal trading time framework to reveal variation in the index price diffusion process that appears before and after 'extreme' events of distinct origin. "Crashes" following internal self-organization and those...

To shed a light on these questions, we analyse a sample of 69 transition risk metrics delivered by 9 different … climate transition risk providers and covering the 1,500 firms of the MSCI World index. Our findings show that convergence … between metrics is significantly higher for the firms most exposed to transition risk. We also show that metrics with similar …
