The Q3 2021 Market Review reveals a mixed performance across global markets. U.S. stocks were flat for the quarter, outperforming both international developed and emerging markets. Growth stocks outperformed value in large caps, but the reverse occurred in small caps. Real estate investment trusts (REITs) in the U.S. posted positive returns, while non-U.S. REITs underperformed. Commodities experienced a strong quarter, with natural gas and cotton being the top performers. Meanwhile, fixed-income markets saw interest rates rise, especially in U.S. Treasuries, leading to modest gains in short-term corporate bonds and mixed results in municipal bonds. The report underscores the importance of maintaining a diversified portfolio and a long-term investment strategy amid market volatility.
