Wiki Attention Earnings Interaction
In plain terms
When Wikipedia pageviews on a stock surge AND there was a recent positive earnings surprise in the past 2 weeks, the typical post-earnings drift gets amplified — go long for 1-3 months.
How it works
When a stock has BOTH (a) high Wikipedia attention (top-decile WoW pageview growth) AND (b) a recent positive earnings surprise (surprise_pct > +5%), the standard PEAD drift is amplified — retail attention reinforces the institutional follow-on buying.
