The report separates observed fund history from simulations, compares products only within compatible cohorts, and preserves known data breaks rather than smoothing them away.
Actual results use that security's observed history. Modeled results apply explicit daily leverage, financing, fee, rebalance, and return-floor assumptions. Modeled series remain separate from live fund history and are excluded from live-history rankings.
Returns use vendor-adjusted close at the daily session. They omit intraday execution, bid-ask spread, slippage, premium/discount, investor taxes, and account-level cash flows; null sessions are dropped, not filled forward.
Multi-day returns compound from the sequence of daily moves. Persistent trends can help; volatile chop can hurt. The route, financing, and rebalance all matter, so 'decay' is neither constant nor guaranteed.
Displayed fees come from current disclosures. Derivative financing, ETN financing formulas, futures roll and basis, spreads, transaction costs, and taxes may sit outside that number or flow through NAV.
Rankings require the same objective family and a common date window. Daily-reset index ETFs, ETNs, single-stock and crypto products, inverse funds, commodities, and stacked portfolios stay in separate cohorts.
Closed, called, or replaced products remain visible as history. CUSIP changes, ticker reuse, leverage or benchmark changes, missing sessions, and short records are flagged; broken series are excluded from rankings.
