Vanguard Ultra-Short Treasury ETF (VGUS)

This exchange-traded fund (ETF) aims to mirror the investment performance of a market-weighted U.S. Treasury index, which is characterized by an exceptionally short dollar-weighted average maturity. Its fundamental investment strategy is an indexing approach, specifically crafted to follow the Bloomberg Short Treasury Index. This benchmark index is comprised of debt instruments issued by the U.S. government that have maturities spanning up to 12 months. It deliberately omits certain types of bonds, such as inflation-protected securities, floating-rate debt, and a few other specific categories. Rather than holding every security within the index, the fund employs a sampling technique. This means it invests in a diverse selection of securities that, when considered collectively, closely replicate the complete index's principal risk factors and other defining characteristics. Under typical operating conditions, the fund allocates the vast majority, and certainly no less than 80%, of its assets to either the securities directly forming the Index or to other investments that the advisor deems to possess virtually identical economic traits. A key objective for the fund is to maintain a dollar-weighted average maturity consistent with that of its benchmark, which, under normal circumstances, is anticipated to fall between 1 and 12 months.
