The four numbers that price an ETF.
What the ETF actually owns.
From the most recent SEC N-PORT filing. The top-10 weight tells you how concentrated the fund is — broad-market trackers run 25-30%, single-theme funds often 50-70%.

What we measure and what we leave out.
Data sources: SEC EDGAR N-PORT filings (holdings + filing-date timestamp); issuer fact sheets for expense ratio + AUM + inception; Yahoo Finance for daily NAV.
Expense ratio is the single biggest forward predictor of long-horizon performance. A 0.03% expense ratio compounds to a fundamentally different outcome than a 0.95% expense ratio over 25 years — even if the underlying index is identical.
Concentration risk lives in the top-10 weight. For broad-market trackers (VOO, VTI, SPY) the top-10 sits around 28-32%. For thematic funds — semiconductors, AI, cannabis — top-10 often crosses 60%. A "sector tilt" with 60% in 10 names is closer to active stock-picking than passive index exposure.
LRS + tax for Indian investors: US-listed ETFs are securities for Indian-tax purposes — held > 24 months = LTCG @ 12.5%, ≤ 24 months = slab-rate STCG. Distributions are dividends taxed at slab rates (US withholds 25%, creditable via DTAA). LRS USD 250,000 / FY cap applies to each remittance.
India-listed alternative: for S&P 500 / NASDAQ-100 exposure without LRS friction, see India-listed ETFs at /etfs/ (Motilal Oswal, Mirae, Nippon, etc. variants). Higher TER but no LRS hassle and INR-settled.
What this page does not model: tracking error vs underlying index, premium/discount to NAV, bid-ask spread on-exchange, currency-hedged variants (e.g. JPST-hedged), securities lending revenue (which subsidises some expense ratios).
ETF NAVs, tracking error and AUM are computed from AMFI disclosures. ETFs are subject to market risk and tracking-error risk. MintByte is an AMFI-registered mutual fund distributor (ARN-314872).
