Earnings Positioning Read

WHAT A WHISPER NUMBER IS. An informal expectation circulating among traders that differs from published analyst consensus. It matters because price reacts to the surprise against what the market ACTUALLY expected, not against the published figure - which is why a company can beat consensus and fall. Whisper numbers are commercially collected, and this analysis licenses no such feed. Naming what a product does not have, rather than approximating it and letting the name imply otherwise, is the standard to expect.

WHAT IT BUILDS INSTEAD, which is a legitimate and different question. It compares the OPTIONS-IMPLIED earnings-day move against that ticker's own historical average earnings-day move and its realised surprise record, then classifies whether the priced-in move is supported by that history.

WHY THAT COMPARISON IS SOUND. The implied move is a market-set price for the event, derived from options spanning the announcement, and it aggregates the views of participants with money committed. Comparing it against how much the stock has ACTUALLY moved on past earnings asks whether the market's current pricing is consistent with the company's own behaviour. That is a well-posed question with an observable answer.

FOUR THINGS TO HOLD ONTO WHEN READING IT.

• IMPLIED IS RISK-NEUTRAL. Option prices embed volatility and jump-risk premia, so implied variance has generally exceeded subsequently realised variance in equity samples. An implied move ABOVE the historical average is therefore the expected baseline condition, not evidence of mispricing - the question is whether the gap is unusual for this name.
• THE HISTORICAL AVERAGE IS A TINY SAMPLE. Four or eight past earnings dates, with wide dispersion. Any average over that many observations is noisy, and the individual absolute moves are more informative than their mean.
• COMPARE ABSOLUTE MOVES. An implied move is two-sided, so it must be set against historical ABSOLUTE moves over a matching window - never signed average returns, which average toward zero.
• A COMPANY CAN CHANGE. A track record reflects the business and management of the past; a new segment, a new chief executive or an acquisition can make the history a poor guide precisely when it looks most stable.

THE FOUR CLASSIFICATIONS ARE THE USEFUL OUTPUT. An elevated move with no supporting history and a muted move despite a volatile history are the interesting cases, because each names a specific disagreement between what is priced and what has happened. Read the disagreement rather than the label.

COVERAGE MAY BE INCOMPLETE PER TICKER, and an absent ticker is unmeasured rather than fairly priced.
