Calculation rules

window: Latest 40 completed benchmark quarters; unavailable issuer evidence remains visible and scores 0.
return Basis: Issuer adjusted close reinvests distributions and normalizes splits; the S&P 500 Total Return Index is the direct benchmark.
point Rule: Strict same-quarter win = 1. Loss, tie or unavailable evidence = 0. No partial or subjective points.
frequency: Quarter endpoints only.
fundamentals: Trailing-four-quarter issuer revenue and EPS growth use the issuer's normalized government-filed facts.
