Vanguard Short-Term Investment-Grade Fund Investor Shares 

This fund aims to provide investors with exposure to a mix of high- and medium-quality debt instruments that carry an investment-grade rating and have relatively short durations. Its portfolio consists of corporate debt, securitized consumer credit, and U.S. government bonds. While it generally offers a more attractive yield compared to money market alternatives, it's important to recognize that its share value will fluctuate. Moreover, rising interest rates can diminish the value of the bonds held within the portfolio, subsequently impacting the fund's share price. This investment could be suitable for individuals with near-term financial goals who are prepared for some degree of principal volatility.
