A "Whisper Number" is a term used to describe an unofficial earnings estimate for a publicly traded company. Whisper numbers are not officially released by the company or by analysts, but instead, are informal estimates that are spread by market participants, including traders and investors.Whisper numbers are often higher than the consensus earnings estimate, which is the average earnings estimate of all analysts covering the stock. The idea behind whisper numbers is that they provide a more optimistic outlook for a company's earnings performance, and may indicate that the company is expected to beat its consensus earnings estimate.Many investors use whisper numbers as a way to gain insight into a company's earnings performance before the official announcement. If a company beats its whisper number, it can result in a positive reaction in the stock price, as investors are often pleased with better-than-expected results.Conversely, if a company misses its whisper number, it can result in a negative reaction in the stock price.It is important to note that whisper numbers are not always accurate and should not be relied upon as the sole source of information for making investment decisions. Whisper numbers are not based on any official or verified data and are simply informal estimates based on speculation and rumors.In conclusion, a "whisper number" is an unofficial earnings estimate for a publicly traded company that is spread informally among market participants. Whisper numbers are often higher than the consensus earnings estimate and provide a more optimistic outlook for a company's earnings performance.However, it is important to note that whisper numbers are not always accurate and should not be relied upon as the sole source of information for making investment decisions.
