What it is
A whisper number is an informal, unofficial earnings per share (EPS) estimate that circulates among market participants, including institutional investors and analysts, prior to a company's official earnings release. These numbers often differ from, and are typically higher than, the widely published consensus estimate. They represent the market's "gut feeling" or a more aggressive expectation based on recent data or anecdotal evidence not yet incorporated into official forecasts.
While not publicly endorsed, whisper numbers can significantly influence stock price movements. If a company's reported EPS beats the consensus estimate but falls short of the whisper number, the stock might still decline, as the "real" expectation was higher. This dynamic illustrates how market expectations extend beyond official analyst reports. Traders often position themselves based on whisper numbers, leading to volatility around earnings announcements.
Why it matters
Whisper numbers reveal hidden market expectations that can drive stock reactions even if official estimates are met. Knowing them helps you understand post-earnings volatility.
