Evidence

Why it moves the price

Higher realised earnings lift the base for future cash-flow estimates, and analysts revise forward numbers upward.

What separates a good call from a naive one

Beats are the norm β€” companies guide so they can beat, so a small beat is already in the price. What actually moves the stock is the *size* of the beat versus the whisper number, and the guidance that accompanies it. A beat paired with weak guidance usually trades down.
