The Revision Is Often the Real Headline

[Shadow Trader]

Headline employment and inflation figures arrive with attached revisions to previous months, and these revisions are sometimes as influential as the new print. A strong new number paired with a large downward revision to the prior month can produce a net signal that is much weaker than the headline suggests.

Algorithms often parse the headline first and the revision seconds later. The result is a recognizable two-step pattern on some releases: an initial move on the headline, then a partial or full reversal once the revision and other details have been processed. Whether that happens depends on the size of the revision relative to the surprise.

Revisions also matter for the baseline. Consensus for the next release is built on the revised level, and the trend narrative that central banks reference, such as the three-month average of job gains, shifts when earlier months change. Policy communication often leans on such averages rather than on a single month.

A practical habit is to read the net change: the new print plus the combined revision to earlier months. A scalper who logs both can later check how often the second move followed the first, without assuming the pattern will repeat.
