In contrast, institutional investors remain active, maintaining their stock holdings despite an increase in Treasury yields.

Viraj Patel, a global market strategist at Vanda, noted in a client update that institutional investors have demonstrated resilience amid macroeconomic volatility. He indicated that options flows from these investors are currently three times higher than usual for September.

Despite the 10-year and 30-year U.S. Treasury yields reaching their highest levels in over a decade, Patel mentioned an uptick in large investor purchases over the past five trading sessions, which he views as a positive indicator of risk appetite among institutions.

Patel highlighted that institutional traders are selectively investing in stocks, particularly in the artificial intelligence sector. Meta Platforms, which saw a nearly 13% increase in stock value following the launch of its Muse Charm device, was identified as a key selection.

While retail investors had a strong year in 2025, helping to redefine their reputation, recent reports from Goldman Sachs reveal a decline in their trading volume share of the S&P 500. This share has dipped over three percentage points below the five-year average since its peak nearly a year ago.

Despite the pressure from rising Treasury yields, the S&P 500 concluded last week with a gain of over 1%, marking a positive trend for the month.
