ETFs were built to make investing simpler. So what happens when the ETFs themselves stop being simple?

A comprehensive snapshot of U.S. ETF market activity in Week 39 (September 21-25, 2026), spanning flows, performance, sector and thematic trends, geographic exposures, asset classes, and leading funds and issuers.

The Four Pillar Strategy is a passive investment model designed to capture global market returns efficiently and at minimal cost. By focusing on four distinct, non-correlated asset classes, this portfolio provides a framework for long-term capital appreciation and inflation protection. The strategy rests on four pillars: Total US Equities, International Stocks, Total Bond Market, and Real Estate Investment Trusts (REITs). The addition of REITs offers an additional layer of diversification.
Built on the foundational principles of diversification, this model allocates 60% of capital to equities for long-term growth and 40% to fixed-income securities to provide a defensive cushion and steady income. Investors have utilized the 60/40 investment strategy to navigate diverse market cycles. The equity portion captures the upside of economic expansion and corporate earnings. Conversely, the bond component acts as a stabalizer. This synergy aims to optimize risk-adjusted returns.
The Yale Endowment Model, pioneered by David Swensen, moves beyond the traditional 60/40 portfolio by emphasizing a diversification into other asset classes, designed to generate equity-like returns with reduced systemic risk. This model prioritizes broad-market exposure while allocating a significant portion to Real Estate (REITs) and inflation-sensitive assets. The fixed-income component is strategically split between Intermediate Treasuries and Treasury Inflation-Protected Securities (TIPS).
