Q-Day

Action

In cryptocurrency derivatives, “Q-Day” historically denoted the anticipated date for the qualification of options contracts for inclusion in certain volatility indexes, particularly the VIX. This qualification process, governed by CME Group, involved assessing the trading volume and open interest of options to ensure they accurately reflected market sentiment. The designation of a Q-Day triggered adjustments to the index composition, impacting volatility-linked products and trading strategies. Consequently, understanding Q-Day schedules is crucial for quantitative analysts and traders managing exposure to volatility risk.
