D1 Capital Bought Tech Stocks, Exited Meta Stake
D1 Capital, run by Daniel Sundheim, reallocated its portfolio in Q1 2026, adding to several major technology and AI-related stocks while exiting others. Regulatory filings show the hedge fund fully sold its stake in Meta (more than 376,000 shares, a position worth over $240 million), and also exited holdings in Synopsys and Arista Networks. The fund trimmed Spotify by about 14% but increased its Amazon position by more than 34%, making Amazon one of its top holdings (worth roughly $376.5 million). Sundheim expanded exposure to AI and semiconductor names — including Broadcom, Nvidia, Alphabet, ASML and Taiwan Semiconductor — and kept Instacart as the fund’s largest holding (about $845 million). The reporting cites regulatory filings and portfolio data from InsiderScore. The article was published May 15, 2026.
Shows a notable hedge-fund reallocation away from a major ad platform (Meta) toward AI, semiconductors and e-commerce — useful signal of investor sentiment but not industry-shifting policy or product news.

Appaloosa Doubles Amazon Stake, Adds Sandisk in Q1
David Tepper’s hedge fund Appaloosa Management substantially changed its disclosed equity holdings in the first quarter, increasing technology and AI-related positions while trimming others. A regulatory filing showed Appaloosa nearly doubled its Amazon stake (a 98% increase), making Amazon its largest disclosed holding at roughly $900 million. The firm also opened a sizable new position in Sandisk (~$179 million), boosted stakes in Uber (+242%), Vistra Energy (+114%), Taiwan Semiconductor (+18%) and Micron (+11%), and increased exposure to the iShares MSCI South Korea ETF (EWY). At the same time Appaloosa reduced holdings in Alibaba (‑33%), trimmed Alphabet (‑3%) and cut Nvidia (‑13%), though Alphabet, Alibaba and Nvidia remained among its top 10 disclosed U.S. equity holdings. The moves underline Tepper’s positioning around AI themes including semiconductors, cloud infrastructure and rising data‑center power demand.
Druckenmiller Bought Amazon and Chip Stocks Pre-Rout
Billionaire investor Stanley Druckenmiller’s Duquesne Family Office increased holdings in AI-linked technology and semiconductor stocks in Q2 2026, according to a regulatory filing. The filing shows the firm raised its Amazon stake to about $129 million and disclosed a new $120 million position in Alphabet. Druckenmiller also boosted positions in Taiwan Semiconductor to $282 million and STMicroelectronics to $232 million, and added smaller stakes in AMD and Palo Alto Networks. Clinical genetic-testing company Natera remained his largest holding at over $800 million as of June 30. The filing covers holdings through June 30, leaving it unclear whether these positions were held or adjusted during the sharp market declines in July.
Three stocks rose with AI rally, three fell
CNBC Investing Club’s July 16, 2026 Monthly Meeting update reports a rotation beneath the market surface: three portfolio stocks gained notably while three declined since the June meeting. Cybersecurity names Palo Alto Networks (+25.5%) and CrowdStrike (+21.7%) hit record highs as investors favored firms seen as benefiting from AI-driven security demand. Meta (+20%) rallied after announcements about monetizing AI (including a planned cloud business and new AI products) and reports it will build a custom AI chip; Apple (+10.7%) advanced amid optimism about its AI roadmap and a multiyear partnership with Alphabet. On the downside, Intel (-15%) and Qnity Electronics (-10.5%) pulled back after a broader semiconductor group rotation, and newly independent FedEx Freight (-12.4%) faced post-spinoff selling. The piece notes portfolio trades by Jim Cramer’s team and frames moves as selective investor positioning around AI and defensive rotation.
