ETF (Exchange-Traded Fund)
An ETF is a fund that trades on an exchange like a stock and usually holds a basket of securities.
Exchange-traded funds let you own a basket — an index, a sector, a bond stack, a commodity — with one ticker and intraday liquidity. The price you pay should stay near the value of the holdings because large dealers can create or redeem shares in kind. When that mechanism works, the ETF is a cheap, transparent wrapper. When it does not, in a closed market or a niche product, the price can drift from the assets.
Stocklytics gives major ETFs their own pages under /etfs so the quote, the move, and the fund's profile load as a full page rather than a broken stock view. Read the expense ratio and what the fund actually holds before you treat the ticker as 'the market.' A leveraged or inverse ETF is a trading tool with daily reset math, not a long-term holding, even though it looks like any other symbol.
Formula
An ETF's market price ≈ net asset value, kept in line by authorized participants creating and redeeming shares.
Live example
Apple Inc. (AAPL) last printed at $345.33 with a market cap of $5.04T. If this symbol is a fund, the price is the tradable quote. Compare it with the holdings' value and the expense ratio before treating a one-day move as the return.

Questions
Is an ETF a stock?
It trades like one. Economically it is a fund. You own shares of the fund, and the fund owns the portfolio.
Why did my ETF not match the index today?
Fees, withholding tax, futures roll, cash drag, or a premium and discount to net asset value. Over years, the expense ratio is the gap you can predict.
