Purchasing Managers’ Indexes (PMI) are economic indicators derived from monthly surveys of private sector companies. Today the latest PMI Manufacturing Index for the US (The ISM Manufacturing Index) came out which was the most negative reading in the last decade.
Global manufacturing PMI’s are rising again though after a record streak of 15 negative months of declines. The last time this index went positive after a long streak of negative PMI’s it was 2009 and that turned out to to be the bottom and a great moment to buy stocks.

The above index has coincided quite nicely with the Bloomberg World Stock Market Cap index which hit a high in January 2018. The index still hasn’t recovered since then.
