ETF returns use the stored Yahoo adjclose series; distributions are modelled as reinvested only where adjustments exist. Identical close/adjclose series are price only. Price-only mode uses closing prices. Fund operating expenses are already reflected in market prices; no separate expense-ratio deduction is applied. Trading fees, taxes and FX are excluded. Leveraged and inverse funds typically target daily returns; compounding can make longer-term results differ from a multiple of the index.
