What the Drop in ISM Suggests for Equities

The recent plunge in the ISM manufacturing index was the largest one month drop since 1984. Some will suggest that it’s a mere slowdown in growth which should naturally be expected in any recovery, but I believe it is indicative of all negative economic surprises as of late that have lead to a sub 3% yield on the 10 year treasury. What is even more ominous is the strong correlation between the ISM and the 1 year rolling return in the S&P 500. Click to enlarge:

An ugly drop in ISM suggests an equity correction?

The adjusted R squared of this duo is above 50%, but if you analyze the data you will find that sometimes the ISM leads, sometimes it happens at the same time, sometimes it is a bit behind. Regardless, it is a very negative reading that actually is just indicative of the other ugly economic news that continues to roll out. Click to enlarge:

Bottom line: It will probably get more interesting from here before it gets boring.

Disclosure: I have no positions in any stocks mentioned, and no plans to initiate any positions within the next 72 hours.
