When a company consistently beats but the stock doesn't react, consensus is usually set too low or the buy-side number is materially above sell-side. Watch for guidance walk-downs ahead of the print.
Raised guidance 3 quarters in a row
SampleConsecutive raises tighten the bar quarter over quarter. Watch the most recent print for the magnitude of the beat — a smaller beat against a higher bar is the early signal that the regime is breaking.
