Methodology & Formulation

Mathematical Chain-Linking & Survivorship Elimination

Primary Source: SEC EDGAR Form 8-K (Item 5.02)
1. Equal-Weight Formulation

w_(i, t-1) = 1 / N_t

Rebalanced quarterly across active constituents, ensuring no single mega-cap dominates the comparative return profile.

2. Daily Chain-Linking

Index_t = Index_(t-1) · (1 + R_t)

Prevents price gaps when executive transitions occur. Turnover takes effect immediately on the official corporate handoff date.

3. Exhaustive Partition

W_t ∩ M_t = ∅ ; W_t ∪ M_t = S&P 100

Every S&P 100 firm belongs strictly to either WSP100 or MSP100, guaranteeing an unbiased mathematical counterfactual.
