美股大跌之际VIX反应异常平静，期权分析师怎么看
Wall Street's Fear Index is doing something strange. Here's what it means for stocks
S&P 500 ditutup turun hampir 2% pada hari Jumaat, dan VIX mencecah paras tertinggi sejak April sebelum jatuh semula untuk ditutup pada 19.4, naik hanya 2.2 mata. Brent Kochuba dari SpotGamma berkata kenaikan itu agak sederhana, dan berdasarkan penyelidikannya berdasarkan 126 penjualan sejak 2018, VIX sepatutnya meningkat kira-kira 2.6 mata.
The S&P 500 fell nearly 2% in a single day while the VIX only rose 2.2 points, lower than the average of historical sell-off samples. This shows that the options market has not priced systemic risks and the panic premium is limited. For gold and foreign exchange traders, this is more like a reduction of leveraged funds than a comprehensive increase in risk aversion. In the future, we need to pay attention to whether the VIX can continue to maintain a high level and whether safe-haven assets really receive capital inflows.
