Does the Coca-Cola Whisper Number Show Investor Confidence?

Coca-Cola Co. (NYSE:KO) is expected to report earnings on Tuesday, April 15. The whisper number is 46 cents, 2 cents ahead of the analyst estimates. Whispers range from a low of 45 cents to a high of 48 cents. Coca-Cola has a 60 percent positive surprise history, having topped the whisper in 29 of the 48 earnings reports for which we have data.

Earnings history:

  • Beat whisper: 29 qtrs
  • Met whisper: 2 qtrs
  • Missed whisper: 17 qtrs

Our primary focus is on post-earnings price movement. Knowing how likely a stock’s price will move following an earnings report can help you determine the best action to take (long or short). In other words, we look at what happens when the company beats or misses the whisper number expectation.

The table below indicates the average post-earnings price movement within a one and 30 trading day timeframe:


The strongest price movement of -0.9 percent comes within 20 trading days when the company reports earnings that beat the whisper number and +1.5 percent within 30 trading days when the company reports earnings that miss the whisper number. The overall average price move is “opposite” (beat the whisper number and see weakness, miss and see strength) when the company reports earnings.

The table below indicates the most recent earnings reports and short-term price reaction:


The company has reported earnings ahead of the whisper number in none of the past four quarters with a whisper number. In the comparable quarter last year, the company reported earnings 1 cent short of the whisper number. Following that report, the stock realized a 3 percent gain in five trading days. Last quarter, the company did not have a whisper number. Overall historical data indicate the company to be (on average) an “opposite” price reactor when the company reports earnings.
