U.S. stock trading may be shifting back toward professional investors. A CNBC report dated September 27 said institutional investors kept participating even as Treasury yields climbed. It also said retail traders made up a smaller share of S&P 500 trading volume. The report presents a possible change in market leadership, not a settled verdict.
What happened
Vanda Research data showed institutional options flows at about three times a typical September level. Institutional stock flows also turned higher during the latest five sessions. That happened while yields on 10-year and 30-year U.S. Treasury securities reached their highest levels in more than a decade. Viraj Patel, Vanda’s global market strategist, viewed the resilience as a constructive signal for institutional risk appetite.
Separately, Goldman Sachs found that retail investors’ share of S&P 500 trading volume had fallen from a peak nearly a year earlier. It was more than three percentage points below the five-year average. The S&P 500 still finished the previous week more than 1% higher. The index also returned to positive territory for the month.
The background
Retail traders had a strong 2025. They were credited partly with buying market dips after President Donald Trump’s tariff rollout. That period gave individuals unusual influence over daily trading. The new data suggests their share of trading volume has weakened. It does not say every retail trader stopped buying.
Institutional investors are not acting as one group. The report describes selective buying rather than a broad rush into every risky asset. Patel’s view was that macroeconomic uncertainty is not ending risk-taking. Instead, it is making institutions more selective about where they place money.
Why the shift matters
The key issue is not simply who feels optimistic. It is who is setting the pace of trading. Institutional investors control large pools of money. Their selected positions can therefore draw attention toward particular stocks. Still, higher activity does not automatically mean that every institution expects prices to rise.
The report’s artificial intelligence example shows this selectivity. Institutional traders were buying certain AI-related stocks. Meta Platforms, the company behind Facebook and AI products, was highlighted as a top pick. Its shares rose almost 13% during the week after its Muse Charm device debuted. Momentum had also been building since Meta introduced its Muse personal AI agent earlier that month.
That example shows where large investors were interested. It does not prove that the device caused the entire gain. Stock prices can reflect several views at once, and the report does not separate each possible cause.
What the data confirms
The short-term contrast is clear. Institutional flows increased, Treasury yields rose, retail investors’ volume share declined, and the S&P 500 still gained. These facts support the idea that large investors remained willing to take selected risks. They do not prove that the entire market has become broadly bullish.
What remains unknown
Five trading sessions are too short to prove a lasting change in market leadership. A threefold increase in options flows shows unusual activity, but it does not show that every institution is bullish. A lower retail share measures the mix of trading volume. It does not reveal every individual’s confidence, holdings, or reason for trading.
The durability of Meta’s rise is also unknown. So is the effect of continued increases in Treasury yields. The report gives a snapshot of current behavior, not a complete forecast.
What to watch next
Watch Treasury yields, institutional flows, retail volume share, S&P 500 performance, and new AI-related information. If institutions keep choosing AI stocks while yields stay high, the selective-risk-taking explanation gains support. If institutional flows reverse or retail participation rebounds, the leadership story becomes weaker.
For now, the careful conclusion is not that individuals lost. It is that large investors have become more visible again.

Who is influencing U.S. stocks now?
📰 Full story: Big Investors Regain Influence as Retail Trading Loses Share
Large professional investors are becoming more important in the U.S. stock market.
institutional investors
Professional investors who manage money for many people or groups.
Treasury yields
Returns from lending money to the U.S. government.
S&P 500
A measure of many large U.S. companies’ stock prices.
💡 The gist
- Professional investors are playing a bigger role.
- Individual traders now make up a smaller trading share.
- Big investors are still choosing stocks carefully.
U.S. stocks are showing a change in who trades them. Institutional investors are large professional investors. They manage money for many people or groups. Retail traders are individuals using their own money.
Vanda Research, a market research firm, studied recent trading flows. It found institutional options flows were about three times normal September levels. Their stock flows also rose during the latest five trading days.
These moves happened while Treasury yields climbed. Treasury yields are returns from lending money to the U.S. government. Ten-year and 30-year yields reached their highest levels in more than a decade.
The article highlights those rising yields because they created a difficult market background. Large investors kept participating despite that pressure. One Vanda strategist called this a constructive sign for risk appetite. However, it may show selective confidence, not a broad market bet.
Retail traders had a strong 2025. Many bought stocks after prices fell following President Donald Trump’s tariff rollout. Goldman Sachs found their S&P 500 trading share had fallen. It was more than three percentage points below the five-year average.
That number measures trading volume. It does not prove that retail traders disappeared.
Big investors are not buying every stock. They are selecting certain artificial intelligence companies. Meta Platforms, the company behind Facebook and AI products, was one example. Its shares rose almost 13% after its Muse Charm device debuted. The report also mentioned Meta’s newer Muse personal AI agent.
Why is this important? Large investors can make selected stocks more noticeable. But the data covers a short period. It cannot prove a permanent change.
Watch Treasury yields and institutional flows. Watch retail volume and AI stock news, too.

Who is moving the stock game?
📰 Full story: Big Investors Regain Influence as Retail Trading Loses Share
Big money managers are moving more stock prices now.
institutional investors
Big money managers who invest for many people or groups.
retail traders
People who buy stocks with their own money.
Meta Platforms
The company that makes Facebook and AI tools.
What happened?
A stock is a tiny piece of a company. People can buy or sell that piece. Retail traders are people using their own money. Institutional investors are big money managers. They hold money for many people.
Recently, these big investors traded more stocks. Retail traders made up a smaller part of trading. That does not mean they all stopped. It means their share became smaller.
The big investors did not buy everything. They picked some artificial intelligence companies. Meta Platforms makes Facebook and AI tools. Its stock rose after a new device appeared.
More buying can make a stock move faster. But nobody knows if this change will last. We will watch the big investors. We will watch individual traders, too.
