Revisions cluster and trend. A company whose estimates are being raised across most of its coverage tends to keep seeing raises, because analysts update incrementally rather than jumping straight to a new view.
For traders, revision breadth is the practical measure: the share of analysts moving up minus the share moving down. It changes the denominator of forward-pe even when the price stands still.
Example: nine of Northwind's eleven analysts raise next-year EPS within a fortnight of the guidance raise, lifting consensus from $0.98 to $1.05 and cutting the forward multiple from 26.5 to 24.8 times.
