Data sources & methodology

League dates: S&P 500: 2026-10-08; Dividend: 2026-10-08; Nuclear & SMR: 2026-10-08 market close (ET). NAV is fund asset value per share. These are calculated NAV total returns in USD; exchange prices and issuer-published performance can differ.

Calculation: (ending NAV / starting NAV) × product of (1 + total cash distribution / ex-date NAV) − 1. Only distributions with ex-dates after the start and on or before the end are included. NAV and cash use the same share basis. Cash is reinvested on the ex-date under this site's method.

Input and comparison limits

Official issuer NAV and distribution records are used where available. SCHD 1Y/YTD, NUKZ historical NAV and URNM NAV include MoneyDJ records. NUKZ critical dates were checked against Weiss and issuer evidence; its unresolved November 28, 2025 daily point is excluded from charts and does not affect these period calculations.

SPYM 2026 cash uses Indeval's explicit gross totals. URNM 1Y uses the finer cash amount reported by Stock Analysis alongside Sprott's rounded notice. Its ex-date reinvestment result differs from issuer performance; the issuer's exact convention has not been confirmed. The common site formula is retained for comparison.

Quoted input precision limits accuracy. The 0.01 percentage point display bucket determines ties; rounded ties do not establish outperformance. Daily charts and weekly form need separate complete histories and may be unavailable. Empty split or event lists do not independently certify the absence of corporate actions.

Trading dates use the versioned US exchange calendar. Benchmark proxies are SPY, SCHD and NLR ETFs; no separate index-return dataset is used. Fund expenses already reflected in NAV are not deducted again. Taxes, trading fees and spreads are excluded.

Ranks cover the selected period. ETFs in a league can hold different assets and carry different risks. Past returns do not predict future returns.

Updates & corrections

Dates beside the rankings and comparisons refer to market close (ET), not live prices. The site checks all 11 funds once each weekday morning after the prior US market close. Each league advances only when every member has complete NAV and distribution data; a delayed league keeps its previous complete results. Cross-fund comparisons use a separate complete common-date snapshot for all 11 ETFs. An "Update delayed" label means the snapshot has passed its update window or the latest release is unavailable; the displayed date still applies.
