Whisper Number Impact: Earnings Preview For Keryx Biopharmaceuticals

This article is now exclusive for PRO subscribers.

Keryx Biopharmaceuticals (NASDAQ:KERX) is expected to report earnings on Wednesday, May 8th. The whisper number is -$0.01, in-line with the analysts' estimate. KERX has a 33% positive surprise history (having topped the whisper in 1 of the 3 earnings reports for which we have data).

Earnings history:

- Beat whisper: 1 qtrs
- Met whisper: 0 qtrs
- Missed whisper: 2 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 +6.1% comes within 30 trading days when the company reports earnings that beat the whisper number, and +7.3% within 20 trading days when the company reports earnings that miss the whisper number. While the strongest price moves are positive, the overall average price movement is inconsistent through 30 trading days when the company reports earnings.

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

Last quarter, the company reported earnings one cent ahead of the whisper number. Following that report, the stock realized a 2.0% loss in one trading day, but turned and ended up with a 6.1% gain in 30 trading days. Overall historical data indicates the company to be (on average) an inconsistent price reactor through 30 trading days when the company reports earnings.

Since 1998, WhisperNumber.com has been tracking and publishing "crowd sourced estimates" for earnings. We call these earnings expectations whisper numbers. Our whisper numbers are gained from individual investors and traders just like you that have registered with our site. While the whisper number itself is an important part of our analysis, a company's "price reaction" to beating or missing the whisper number expectation is the key. On average, companies that exceed the whisper are "rewarded," while companies that miss are "punished" following an earnings report. Trading on whispers is a technical play on market psychology, rather than a bet on a company's fundamental strengths.
