possible trading strategy?

[Moonshine]

this worked for a while in the past. Wall St used to habitually underforecast earnings. In the late 90's when the internet came about, a bunch of sites rose up that gave extremely accurate earnings predictions. Owners of the sites later fessed up that all they were doing was taking wall st forecasts and revising them upwards X percent every time.

Long story short, no, you cant generate alpha by doing this strategy (and if you could in theory it would immediately go away)
