At the end of the day on Tuesday, February 6, 2018, a snapshot of the Dow and 10 year Treasuries was as below:
At the dip of the stock market on Tuesday, there was also a dip in the yield of the 10-year notes (red line on the images).
I want to know if the following would be a good interpretation:
As the marked plunged in the middle of the day on Tuesday, big investors cashed out of the stock market and sought refuge in the bond market. At the lowest point in the graphs (middle of the day), the yield of the 10 year notes went down as more demand for bonds raised their price. At the end of the day, the stock market bounced back, and the 10 year Treasuries price went down (yield moved up).
I'm explaining it to myself. Basically, I want to make sure that the underlying ideas are not messed up: risk aversion makes money flow from stocks to bonds; this results in a rise in the price of bonds, which, in turn, decreases the yield. Also, not being even close to a professional investor, I wanted to know if the effect (the velocity) is that fast as to almost be able to superimpose both graphs.
