The published consensus estimate isn't always the number that actually determines a stock's reaction — a informal secondary expectation often matters just as much.
The Distinction
The consensus estimate is a formal average of professional analysts' published EPS and revenue forecasts. A whisper number is an informal, unofficial expectation circulating among traders — often reflecting more current sentiment than the sometimes-stale published consensus, since analyst estimates can lag recent developments. When a stock reacts unexpectedly to a "beat" against the official consensus, a gap against the unofficial whisper number is a common explanation.
Whisper numbers are harder to pin down than the published consensus — no single official source tracks them — but checking recent options market positioning and analyst commentary in the days immediately before a report can reveal where actual trader expectations have shifted beyond the stale official consensus.
Someone Confused by an Unexpected Reaction to a Published Beat: Consider whether the informal whisper number may have been higher than the official consensus.
Someone New to This Concept: Treat whisper numbers as a secondary signal — useful context, not a replacement for the official consensus.
Use Estimates the Way
- Check the official consensus as your baseline expectation.
- Watch for signs the whisper number may diverge from it ahead of a report.
- Don't treat either as a guarantee of the actual result.
