Coverage initiations across 2,268 names
Coverage initiations were measured across 2,268 names over the last three years; 48% of them have a positive median reaction at 30 minutes. An analyst starts covering a name. New coverage tends to be constructive — but the reaction varies by name.
Coverage initiations do not move one way.
AAPL initiations were among the most reliably positive classes measured: median +0.48% at 30 minutes with 85% of events up; AMD initiations popped hardest (median +1.02%).
Across all 2,268 measured names, 48% have a positive median 30-minute reaction and 246 have a median of exactly 0.00%. No single median is published for the class: with the names split that evenly, the middle of that distribution is zero, and it is zero on all six of these pages.
