« Multifractal Cryptocurrencies »

We model high-frequency cryptocurrency returns with a Markov-Switching Multifractal process (MSM; Calvet and Fisher 2001). We use Approximate Maximum Likelihood (AML; Czellar, Frazier, and Renault 2022) to estimate all the parameters of the MSM model, including the number k of hidden states. The MSM model accurately predicts major cryptocurrency returns and its prediction power is largely superior to those of GARCH-type alternatives. Furthermore, we propose a trading strategy based on dynamic Sharpe ratio signals generated through the MSM model at high-frequency. The strategy generates substantial returns, proving resilient to the high trading fees and execution delays common in cryptocurrency exchanges.

Kind regards,
Jeremy Heng, Olga Klopp, Roberto Reno, and Marie Kratz
