Investors are growing more confident in the post-pandemic recovery, which is spurring movement into corporate bonds, a good sign for the Vanguard Long-Term Corporate Bond Index Fund ETF Shares (VCLT). As per the fund description, VCLT seeks to track the performance of a market-weighted corporate bond index with a long-term dollar-weighted average maturity. "The premium between corporate debt and US Treasuries has dropped to its lowest level in more than a decade in a sign that investors are growing confident recent rises in inflation will not hinder the economic recovery," a Financial Times article said.
