The second quarter of 2025 marked a decisive moment in institutional investing. Hedge funds and asset managers leaned heavily into technology, with Apple, Microsoft, Nvidia, and Amazon emerging as the top net buys by value in 13F filings. Together, these four companies accounted for trillions in net inflows, underscoring investor conviction in AI-driven growth, hyperscaler infrastructure, and resilient consumer ecosystems.
The Big Four: Net Buys by Value
- Apple Inc. – USD 2.32 trillion
Despite Berkshire Hathaway trimming its stake, Apple remained the most accumulated stock. Its blend of consumer loyalty and ecosystem stickiness continues to make it a defensive yet growth-oriented cornerstone. - Microsoft Corp. – USD 2.21 trillion
Microsoft’s Intelligent Cloud segment grew revenues nearly 39% YoY, fueled by Azure AI expansion. Institutional investors doubled down on its role as the backbone of enterprise AI adoption. - Nvidia Corp. – USD 1.85 trillion
Nvidia’s dominance in semiconductors and AI chips drove massive inflows. Bridgewater Associates boosted its stake by 154% (~USD 1.1B), reflecting confidence in the company’s unrivaled position in AI infrastructure. - Amazon.com Inc. – USD 1.3 trillion
Pershing Square initiated a ~USD 1.3B stake, betting on Amazon’s cloud and AI strategy despite conservative earnings guidance. Its dual strength in e-commerce and AWS made it a compelling long-term play.
