The S&P 500 climbed 10.6% in Q2 2025. Hedge funds? They averaged 8.2%. That gap tells you something important: the smart money isn't chasing the index—they're rotating into specific bets while the market grinds higher.

Q2 13F filings just dropped, and they show a clear pattern. Hedge fund assets hit a record $5 trillion with $24.8 billion in net inflows—the highest quarterly inflow since 2014. That money's going somewhere specific, and it's not where most retail investors are looking.

According to Morgan Stanley's analysis of the filings, funds made aggressive moves into growth and cyclical sectors while dumping defensives. The rotation was sharp, concentrated, and tells a story about where institutional money thinks the next phase of returns will come from.

The Big Sector Shifts

Here's where the money actually moved in Q2:

What Drove It

Technology

+1.9%

AI and semiconductor plays, especially NVIDIA; still underweight since the 2017 peak

Industrials

+0.6%

Housing recovery and defense spending (Lennar, RTX)

Communication Services

+0.6%

Selective adds in streaming and social media (Alphabet)

Healthcare

-1.3%

Trimmed amid regulatory pressure, though small-cap biotech interest persists

Financials

-0.7%

Bank sells (Bank of America getting hammered); small-cap financials bucked the trend

Consumer Staples

-0.7%

Defensive unwind as volatility fears eased

The pattern is clear: funds are betting on growth and cyclicals, not safety. Tech got the biggest allocation increase despite being expensive. Healthcare, traditionally a defensive hedge, got cut hard—except for one very specific contrarian play we'll get to.

For small-caps (Russell 2000 proxy), the rotation was even sharper:

Consumer Discretionary

Small-cap tech got a massive boost. Consumer Staples and Healthcare got dumped. That's not defensive positioning—that's betting on cyclical acceleration.

Where the Marquee Funds Stand

A tracker of five big-name funds—Berkshire Hathaway, Appaloosa, Yacktman, Pershing Square, and Millennium—shows persistent overweight and underweight positions versus the S&P 500. These funds averaged 8.2% returns in Q2, with 2 out of 5 outperforming the index.

Pershing Square is wildly overweight in Consumer Discretionary at 57% of the portfolio. Berkshire is sitting heavily in Financials and Energy. Millennium slashed Meta by 62%. These aren't index-hugging positions—they're concentrated bets.

The Stock-Level Action: Who Got Bought, Who Got Sold

Hedge funds executed over $50 billion in net U.S. equity trades via 13F filings. Here's where the dollars actually went:

The pattern here is fascinating. Funds piled into NVIDIA and Amazon—consensus AI plays. But they also made a huge contrarian bet on UnitedHealth, which got destroyed earlier in the year on regulatory fears. Berkshire and Appaloosa both went big, with Appaloosa increasing its position by 1,300%.

Meanwhile, they trimmed or dumped megacaps like Apple, Microsoft, and Meta. Even Berkshire, famously loyal to Apple, cut 7%. That's rotation within tech—out of mature platforms, into AI infrastructure.

Four Key Takeaways

1. The AI pile-in is real: NVIDIA, Alphabet, Microsoft, Broadcom, Amazon—funds are consensus buyers. Tech stocks now make up 23% of total hedge fund holdings, the largest sector allocation. The bet is clear: AI drives the next wave of growth, and these are the primary beneficiaries.

2. Healthcare is split: The sector saw the largest net allocation decrease overall, but a handful of high-profile managers—Buffett, Burry, Tepper—made massive contrarian buys on UnitedHealth. That's a vote of confidence that regulatory fears are overdone and the stock's beaten down enough to be attractive.

3. Geographic pivot away from China: Funds reduced China exposure due to geopolitical and regulatory risks, while building new positions in domestic U.S. sectors like homebuilding and industrials. Berkshire's new positions in Lennar and D.R. Horton signal confidence in the U.S. housing recovery. Meanwhile, Bridgewater (Dalio) executed a "Full China Exit," with others starting to trim their holdings.

4. Rate cuts change the game: While Q3 13F data isn't public yet, preliminary ETF flows and bank outlooks suggest emerging interest in new areas following the Fed's September rate cut. The rotation might be shifting again.

What This Means for You

13F filings are backward-looking—they show what funds held as of June 30, not what they're doing now. But they reveal positioning and conviction. The themes are clear:

  • AI infrastructure is still the dominant growth bet

  • Defensives are out of favor

  • Selective contrarian plays (UnitedHealth) attract big money when valuations get cheap enough

  • Small-cap tech is getting attention as a cheaper way to play the AI theme

The rotation from defensives into growth and cyclicals tells you funds aren't bracing for recession—they're positioning for continued expansion, albeit with more volatility. The fact that they're willing to trim Apple and Microsoft to add NVIDIA and Amazon shows they're chasing specific narratives, not just index weight.

If you're trying to front-run institutional money, the message is: growth over defense, AI over legacy tech, and selective contrarian bets when regulatory fear creates opportunity. That's what $5 trillion in hedge fund assets is doing. Whether they're right is another question, but that's where the smart money is flowing.
