Institutional Investors Drive Stocks as Bond Yields Rise

Institutional investors have remained active in U.S. stocks despite a sharp rise in Treasury yields, while retail traders’ share of the market has declined, according to CNBC.

Vanda global market strategist Viraj Patel said institutional options flows were about three times higher than in a typical September and had increased over five sessions even as 10-year and 30-year Treasury yields reached their highest levels in more than a decade. He described the activity as a “reasonably constructive signal for risk appetite,” saying large investors were selectively buying artificial-intelligence-related stocks rather than broadly retreating from risk.

Meta Platforms was among the favored names identified by Patel. Its shares rose almost 13% in the week after the company introduced its Muse Charm device, following the earlier unveiling of its Muse personal AI agent.

Retail participation, by contrast, has receded after strong performance in 2025. Goldman Sachs found that retail investors’ share of S&P 500 trading volume had fallen to more than three percentage points below its five-year average.

The shift came as a government-bond selloff pushed yields higher in the United States and Europe, according to The Wall Street Journal, and MarketWatch reported that bond yields moved higher. Despite that pressure, the S&P 500 gained more than 1% last week and moved into positive territory for the month.
