According to TechFlow, on December 25, Greeks.live analyst Adam posted on social media that the difference between option skews of different maturities has been enlarged. Since the bull market at the end of this year, the skews of different maturities have been very close, fluctuating around 5%, and the difference between them is mostly no more than 1%. However, with the recent adjustment, the difference has begun to enlarge, and the short-term skew has dropped significantly.

These data show that the market's enthusiasm has obviously declined, and the optimism of option market participants for January has weakened.
