Wu said that according to GreeksLive analysis, as the quarterly delivery is about to begin at the end of June, the forward option trading volume has increased significantly this week, mainly in the form of large call option combinations. The option data shows that although the RV fluctuates greatly, the IV has been relatively stable in the past two weeks, both in absolute value and in terms of change level. According to past experience, there is often no big market before the quarterly delivery. The trend in the second quarter of this year is relatively weak, which is also in line with the historical experience of previous years. The trend in the third quarter is generally struggling, and the end of the third quarter is usually the node for the market to pick up.
