Repeated misses without a guidance reset suggest management is structurally optimistic relative to operating reality. Track whether next-quarter guidance is being benchmarked off the prior miss or the prior plan.
Missed in 4 of the last 4 quarters
SampleRecent misses matter more than long-window beat rate — the trailing 12 months drives the analyst model and the next-print bar.
