iShares 20+ Year Treasury Bond is an Exchange-Traded Fund (ETF) that holds a collection of underlying securities designed to track a specific index, sector, commodity, or strategy. You can view its full holdings and prospectus on the fund provider's website or on Yahoo Finance. The market cap shown here reflects the total value of all outstanding shares of the ETF.

The expense ratio is the annual fee iShares 20+ Year Treasury Bond charges investors, expressed as a percentage of assets under management. Lower expense ratios mean more of your investment compounds over time. Index-tracking ETFs typically have very low expense ratios, while specialty or actively managed ETFs may charge more. Check the fund provider's official page for the current expense ratio.

For an ETF, market cap and assets under management (AUM) are closely related — both reflect the total value of the fund's shares outstanding. As more investors buy shares, new shares are created through an authorized participant mechanism, growing the AUM and market cap. Conversely, outflows reduce shares outstanding and shrink the fund's size.

Yes, ETF shares trade on an exchange and can briefly trade at a premium or discount to their underlying NAV. However, for large, liquid ETFs this gap is typically very small — often just a few cents — because arbitrageurs profit by closing the gap. In volatile or illiquid markets, premiums and discounts can widen more significantly.

ETF suitability depends on your investment goals, risk tolerance, and time horizon. Broad index ETFs are widely used as long-term core holdings due to their diversification and low costs. Leveraged, inverse, or highly concentrated ETFs carry significantly more risk and are generally not intended for long-term buy-and-hold investing. Always consult a financial advisor before making investment decisions.
