The chart shows the PMI and the ISM, two separate US surveys of manufacturing sentiment about sales, production, etc. The ISM used to be called the NAPM survey, and it's correlated very well indeed with economic growth, both big and smaller cycles, over 70 years. The ISM survey has a much shorter history, but the two move more or less together.
Both are strengthening.
Disclaimer. After nearly 40 years managing money for some of the largest life offices and investment managers in the world, I think I have something to offer. These days I'm retired, and I can't by law give you advice. While I do make mistakes, I try hard to do my analysis thoroughly, and to make sure my data are correct (old habits die hard!) Also, don't ask me why I called it "Volewica". It's too late, now.
BTW, clicking on most charts will produce the original-sized, i.e., bigger version.
