Post-Earnings Announcement Drift
In 1968, Ray Ball and Philip Brown found that stocks keep moving in the direction of an earnings surprise after the news is already public. Six decades later it still happens — but the reason it is hard to see is the yardstick. Measured against the published consensus, a beat is a beat. Measured against what investors actually expected, the same report can be a disappointment, and the stock spends the next week telling you so.

is confirmed to report Wednesday, September 30, after the close.
Micron heads into its fiscal fourth-quarter report riding one of the most dramatic guidance progressions in recent memory, yet the stock has fallen 15% since its last print even as the S&P 500 climbed nearly 5%. That divergence between operating momentum and share performance sets up an unusually pointed question for this release: has the market already priced in the good news, or is it losing confidence in a narrative that management has described in increasingly triumphant terms.
Consensus calls for $31.24 in earnings on $50.76 billion in revenue, essentially in line with management's own guidance of $30 to $32 per share and $49 billion to $51 billion issued last quarter. The Earnings Whisper of $34.14 sits meaningfully above the Street consensus, suggesting whisper-number watchers expect another beat rather than a mere in-line quarter. That said, Micron has trained investors to expect upside after three consecutive quarters of guidance that undershot actual results by wide margins, so a beat here may be viewed as table stakes rather than a fresh catalyst.
