Wu Shuo learned that according to Greekslive, with the release of PPI and CPI data, market volatility expectations have dropped significantly, resulting in a significant drop in the implied volatility (IV) of each major term. Short-term IV fell by more than 20% this week, and medium- and long-term IV Also down about 5%. This is a rare drop, with institutional sellers profiting handsomely from the decline, making up for losses from hedging over the past month. The current term structure has returned to far high and near low, the market may enter a period of stability, and the price/performance ratio of selling mid-term options looks better.
