Breadth thrusts
Mixed result in its pre-registered test
A breadth thrust (the share of advancing stocks jumping from under 40% to over 61.5% within ten sessions) has happened 11 times since 2003, most recently on 8 April 2026. The Nifty 500's average return over the next six months was 14.9% against 8.8% on all days (p = 0.11, so it could be chance), and over the next year 30.7% against 18.3% (p = 0.03, unlikely to be chance). That is 11 signals, so one or two years carry the result.
