Several of Wall Street’s largest hedge funds boosted investments in major tech companies during Q2 2024, recent securities filings show.

Bridgewater Associates, Tiger Global Management, and Discovery Capital increased stakes in Nvidia, Alphabet, Microsoft, Amazon, Meta Platforms, and other AI-related stocks.

Bridgewater more than doubled its Nvidia holdings to 7.2 million shares valued at US$1.1 billion.

It also increased positions in Alphabet and Microsoft. Discovery Capital doubled its stake in America Movil, took new positions in Nvidia-backed CoreWeave, and raised its stake in Meta.

Tiger Global added about 4 million Amazon shares, ending June with 10 million worth US$2.3 billion, and bought more shares in other tech and AI companies.

Coatue Management opened new positions in Arm Holdings and Oracle, and raised its stake in CoreWeave.

These shifts came as hedge funds reduced exposure to aerospace, defense, and consumer retail.

🧠 Food for thought

1️⃣ Momentum investing cycles drive hedge fund concentration in dominant sectors

The hedge funds’ return to Big Tech reflects how momentum investing creates self-reinforcing cycles that can override fundamental concerns.

Earlier this year, these same funds had pulled back from tech stocks due to tariff volatility and AI bubble fears, but the sector’s strong performance has now drawn them back in. The S&P 500’s 10% gain this year, driven largely by tech companies that represent nearly a third of the index’s market cap, demonstrates how momentum can compound rapidly.

This pattern shows how institutional investors often follow price trends rather than contrarian positioning, even when they have sophisticated analytical capabilities.

The shift away from aerospace and defense, despite ongoing geopolitical tensions, illustrates how momentum can influence investment decisions even when other factors might suggest strength in those sectors.

2️⃣ Hedge funds’ tech dependency mirrors their tech stock concentration

The industry’s heavy investment in Big Tech stocks parallels hedge funds’ own increasing reliance on technology for competitive advantage.
