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 Jumat, dan VIX mencapai level tertinggi sejak April sebelum jatuh kembali ditutup pada 19,4, naik hanya 2,2 poin. Brent Kochuba dari SpotGamma mengatakan kenaikan tersebut relatif kecil, dan berdasarkan penelitiannya berdasarkan 126 aksi jual sejak 2018, VIX seharusnya naik sekitar 2,6 poin.
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.
