Southwest Airlines (NYSE:LUV) is expected to report earnings on Thursday, January 23. The whisper number is $0.27, two cents short the analysts’ estimate. Whispers range from a low of $0.24 to a high of $0.30. LUV has a 63 percent positive surprise history, having topped the whisper in 26 of the 41 earnings reports for which we have data.

Earnings history:

– Beat whisper: 26 qtrs
– Met whisper: 1 qtrs
– Missed whisper: 14 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 thirty trading day timeframe.


The strongest price movement of -1.5 percent comes within thirty trading days when the company reports earnings that beat the whisper number, and -2.7 percent within thirty trading days when the company reports earnings that miss the whisper number. The overall average price move is ‘negative’ (beat the whisper number and see weakness, miss and see weakness) 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 one of the past four quarters with a whisper number. In the comparable quarter last year, the company did not have a whisper number. Last quarter, the company reported earnings two cents short of the whisper number. Following that report, the stock realized an 11.5 percent gain in thirty trading days. Overall historical data indicates the company to be (on average) a ‘negative’ price reactor when the company reports earnings.
