This paper investigates price jumps in commodity markets. We find that jumps are rare and extreme events but occur less frequently than in stock markets. Nonetheless, jump correlations across commodities can be high depending on the commodity sectors. Energy, metal and grains commodities show...

The introduction of derivatives on Bitcoin enables investors to hedge risk exposures in cryptocurrencies.
