Remember that we mentioned from now on, we need to focus on this chart. The drop of 220 points yesterday is caused by this rising yield of the 10 year treasury note, also is regarded as the long term interest rate.
Do pay attention to it as the coming months can be volatile if yield continue to rise... 2.77% now.
This happens when we are still adjusting to a rising interest rate.
