The VIX is seen as a measuring stick for how worried investors are about the possibility of a stock selloff. It is based on S&P 500 index options for 30 days following the measurement date and is often referred to as the fear gauge.
With US/China trade issues being far from finding any sort of common ground, the market seems to be bracing for more turbulence to come. Treasury bond yields, usually a haven when investors worry, were down again. The 10-yr dipped below 4% briefly (1), and the 30-yr dropped to 4.59% (2), as I write, both down 10 basis points since Oct 1st.
