A Golden Finance report states that the former US Treasury Secretary, Summers, has called for an investigation by the Comissão do Mercado de Valores Mobiliários (SEC) and related exchanges into the surge in the panic index (VIX) on Monday, August 5th. My understanding is that due to the use of some non-liquidity tools in calculating the VIX index, the fluctuation of the VIX index on Monday may have been somewhat artificial, Summers said on a TV show on Friday. After the surge in the VIX index on Monday, experts measuring volatility say that the violent fluctuations of the index may be caused by several technical factors, including a significant lack of liquidity, the failure of some short positions betting on volatility, or simply the way volatility is calculated.
