Key takeaways
Equity spotlight
Surging U.S. stocks in recent years have made equity benchmarks including the Standard & Poor’s 500 Index top-heavy with tech giants, raising concerns about overconcentration and overvaluation. Advisors are already shifting portfolios more toward small- and mid-cap stocks, but addressing home bias by adding more international stocks could further diversify portfolios and mitigate these risks.
Fixed income spotlight
During the second half of 2024, the yield differential between 2-year and 10-year Treasury bonds turned positive, ending the longest period on record of yield-curve inversion. Despite ongoing economic uncertainty, the restoration of the Treasury term premium and higher yields suggest rethinking allocations to Treasuries, with longer-term bonds offering potential return and diversification benefits.

Vanguard ETF Shares are not redeemable with the issuing Fund other than in very large aggregations worth millions of dollars. Instead, investors must buy and sell Vanguard ETF Shares in the secondary market and hold those shares in a brokerage account. In doing so, the investor may incur brokerage commissions and may pay more than net asset value when buying and receive less than net asset value when selling.
