Q4 2025 hedge fund filings began rolling in after the February 17 deadline, offering a clear snapshot of a market in transition. The world's largest and most sophisticated investment firms have made some big rotations, with some piling into AI and mega-cap tech, while others rotated toward defensive plays to diversify their market exposure. | Before diving in, a quick reminder: the stocks that you see aren't recommendations to follow blindly. Hedge funds have different time horizons, risk tolerances, and strategies than most investors. But understanding where institutional capital is moving provides valuable context for market positioning. Here's what the four biggest hedge fund players did with their money when 2025 ended. |
|
| | Bridgewater Associates: All-In on AI and Growth | Portfolio Size: $27.4 billion | Holdings: 191 new purchases, 450 additions |  | Source: Fintel |
| Ray Dalio's macro-focused giant made its intentions clear in Q4: double down on artificial intelligence and industrial exposure while trimming legacy tech positions. The firm's 54% increase in Nvidia, combined with new positions in Dell and Spotify, signals conviction that the AI infrastructure build-out has room to run despite sky-high valuations. | What They Bought | Stock | Ticker | Change | Move | Nvidia | NVDA | +1.36M shares | +54% QoQ Increase | Amazon | AMZN | Increased | Major boost | Dell Technologies | DELL | 156,300 shares | New position | Caterpillar | CAT | 62,200 shares | New position | Spotify | SPOT | 23,500 shares | New position |
| What They Sold | Stock | Ticker | Change | Move | Lam Research | LRCX | -422,300 shares | -12% of total holdings | AT&T | T | Full exit | -100% | Annaly Capital | NLY | Full exit | -100% | Salesforce | CRM | Sold 75,000 shares | -4% | Adobe | ADBE | Biggest Trim | −1.75% |
| The takeaway: Bridgewater is rotating from defensive dividend plays (AT&T, Annaly) into concentrated AI winners. The Caterpillar addition suggests they're betting on infrastructure spending tied to data center construction. Exiting REITs and telecom while buying AI signals a clear risk-on pivot. |

| Izzy Englander's multi-strategy behemoth made the most eye-popping move of Q4: a massive $3.9 billion bet on Walmart, increasing their position significantly. This is not just a simple rebalancing, but a statement. Meanwhile, they trimmed high-flying software names like Microsoft as well. | What They Bought | Stock | Ticker | Change | Position Value | Notes | Walmart | WMT | +37.08M shares | $4.54B total | #1 Single Stock Addition | iShares S&P 500 ETF | IVV | +7M shares | $9.93B total | #1 Position addition | Apple | AAPL | Increased | +$1.8B | Major addition | iShares Russell 2000 ETF | IWM | Increased (puts noted) | +$3B | Hedged small-cap exposure | Invesco's QQQ Put Option | QQQ | Big increase | 2.25% of portfolio | Big hedge against Tech |
| What They Sold | Stock | Ticker | Change | Move | SPDR S&P 500 ETF | SPY | Reduced | -$3.4B | AppLovin | APP | Reduced | -$1.9B | Palantir | PLTR | Reduced | -$792M | Oracle | ORCL | Reduced | -$637M | Nvidia | NVDA | Also trimmed | -$560M |
| The takeaway: Millennium is hedging both ways on tech, buying some tech stocks, while buying big put options, a classic multi-strategy approach. The Walmart surge signals conviction that value retail wins in a consumer environment where budget-conscious shoppers dominate. Trimming Palantir and AppLovin after massive runs suggests profit-taking on speculative software. |
|
| | Elliott Investment Management: Energy and Activist Focus | Portfolio Size: $23 billion | Holdings: 35 (highly concentrated) |  | Source: Fintel |
| Paul Singer's activist powerhouse maintains one of the most concentrated portfolios among major funds, with 73% of assets in top positions. Q4 showed continued conviction in energy and precious metals despite broader market volatility. Elliott's approach is surgical: maintain fewer positions, place bigger bets, and longer holding periods. | What They Bought | Stock | Ticker | Change | Position Value | Move | Energy Sector SPDR | XLE (inferred) | New sector exposure | $1.18B | New | PepsiCo | PEP | Increased | +$179M | Adding defensives | Triple Flag Precious Metals | TFPM | Maintained/increased | Top holding | Core position (19%) | Phillips 66 | PSX | Maintained | Top holding | Refining exposure | Suncor Energy | SU | Unchanged | $2.2B | Stable conviction |
| What They Sold | Stock | Ticker | Change | Move | Southwest Airlines | LUV | -2.85M shares | Reduced to $1.63B | Liberty Broadband | LBRDA | Reduced | -$235M | Various exits | Multiple | 7 positions exited | -100% | Reduced Invesco QQQ, Russell 1000, and Tech Put | Multiple | Biggest cuts | Trimmed almost 4% of portfolio value in puts |
|
|
| The takeaway: Elliott is playing the energy bifurcation trade as the owning refiners and processors (Phillips 66) that benefit from stable fuel demand while avoiding upstream E&P exposed to low oil prices. The precious metals position (Triple Flag) provides portfolio insurance. Exiting Southwest suggests reduced conviction on airline recovery despite travel strength. | | AQR Capital Management: Quant Rotation Toward Healthcare | Portfolio Size: $191 billion | Holdings: 3,000+ positions |  | Source: Fintel |
| Cliff Asness's quantitative giant doesn't make emotional bets, but they rely on algorithms to identify systematic mispricings across thousands of stocks. Q4's rotation into healthcare and utilities while trimming managed care suggests their models are flagging defensive sectors as relatively undervalued, while growth-oriented healthcare services look stretched. | What They Bought | Stock | Ticker | Value ($MM) | Portfolio % | Move | PayPal Holdings Inc. | PYPL | 297.13 | 0.1559 | #1 Increase | Celestica Inc. | CLS | 315.50 | 0.0390 | Increased | Deutsche Bank Aktiengesellschaft | DB | 309.48 | 0.0383 | Increased | Corpay Inc. | CPAY | 99.47 | 0.0522 | Increased | The Bank of Nova Scotia | BNS | 262.28 | 0.0324 | Increased |
| What They Sold | Stock | Ticker | Value ($MM) | Portfolio % | Move | NVIDIA Corporation | NVDA | 4,893.57 | 0.6052 | Biggest decrease in % | Microsoft Corporation | MSFT | 3,030.17 | 0.3747 | Decreased | Apple Inc. | AAPL | 3,398.66 | 0.4203 | Decreased | Roblox Corporation | RBLX | 832.97 | 0.1030 | Decreased | Amazon Inc. | AMZN | 2,059.57 | 0.2547 | Decreased | Broadcom Inc. | AVGO | 1,553.36 | 0.1921 | Decreased |
| The takeaway: AQR trimmed mega-cap AI and tech leaders like Nvidia, Microsoft, Apple, and Amazon, signaling reduced exposure to crowded growth trades. At the same time, it added to payments and global financials, including PayPal, Deutsche Bank, and Bank of Nova Scotia. The shift points to a valuation-driven rotation from expensive momentum names into cheaper financial exposure. |
|
| | What Does This All Mean for Regular Investors | The Q4 hedge fund filings reveal a market where institutional capital is making clear directional bets rather than staying balanced: | AI exposure requires position management. With Bridgewater adding heavily to Nvidia while AQR systematically exits, the institutional bid is no longer one-directional. There is a feeling of uneasiness among hedge funds regarding AI, and it couldn't be more evident. Institutions are buying insurance they hope not to use. Millennium dropped 2.25% of its portfolio on QQQ puts while buying Walmart and Apple. Elliott trimmed 4% worth of tech puts. Why hedge so aggressively if you're confident? They're not. They're positioned for the rally to continue, but terrified it won't. Monitor quant fund positioning for valuation signals. AQR's systematic reduction across all Magnificent Seven names provides an early warning. For quantitative models, this isn't rebalancing — it's an exit strategy. When quantitative models that beat markets for decades say "overvalued," listening late costs money. Consumer discretionary bifurcation offers an opportunity. Millennium's conviction in Walmart versus trimmed premium discretionary creates a clear trade: overweight value retail, underweight premium brands.
| The key takeaway: reduce conviction in crowded trades, implement downside protection, rotate toward valuation, and recognize that institutional positioning reflects hedged optimism, not unqualified bullishness. | Position accordingly. |
