The shape of the vol-curve in SPX and single names. I assume that you're referring to the CBOE ticker, which has not moved.

Cboe SKEW has a greater weight to OTM strikes and is at 145...which is quite elevated compared to the past 20 years. Barclays SKEW is not as elevated because they measure more near term stikes. The single name skew is low due to the call buying, but the index skew is elevated...so what is wrong with my conclusion that Softbank bought single name calls and index puts?
