Macro researcher Adam@Greeks.live released this week's market outlook on the X platform, pointing out that this Friday is the annual delivery day, and nearly half of the options positions will face delivery, releasing a huge amount of margin and putting immense pressure on implied volatility (IV).
Currently, IV for options after mid-January remains high and faces the greatest pressure. There may be a significant decline before and after delivery. Short-term selling convex yield treasure or adding some timing-based sales would be more cost-effective.
