ETF
Exchange-Traded Fund: A type of investment fund that trades on a stock exchange, just like an individual stock. ETFs typically hold a basket of assets (stocks, bonds, commodities) and offer instant diversification at low cost.
Expense Ratio
The annual fee an ETF or mutual fund charges to manage your money, expressed as a percentage of your total investment. Higher expense ratios reduce your net returns over time.
Liquidity
How easily you can buy or sell an asset without moving its price. High liquidity means large orders fill with little price impact.
Tracking Error
How closely an ETF follows the performance of its target index. Lower tracking error means the ETF is doing a better job of replicating the index returns (before fees).
Diversification
Spreading risk across different assets, strategies, or markets so a single bad event cannot seriously hurt the whole account.
Index Fund
A type of investment fund (ETF or mutual fund) designed to replicate the performance of a specific market index, rather than trying to beat it through active management. Known for low costs and broad diversification.
