Billionaire hedge fund manager Michael Platt has made a dramatic shift in his portfolio, dumping four of the Magnificent Seven tech stocks and pouring capital into Taiwan Semiconductor Manufacturing (TSMC).

Platt, co-founder and CEO of BlueCrest Capital Management, oversees a European hedge fund with over $1.6 billion in 13F securities, according to Detik Finance.

Exiting Major AI Players

Regulatory filings reveal that during the first quarter of 2026, Platt completely sold his positions in Nvidia, Microsoft, Meta Platforms, and Amazon.

The Nvidia stake had been purchased in the second quarter of 2025 and represented nearly 0.2% of his portfolio.

Microsoft shares, which made up 0.1% of the portfolio since the third quarter of 2023, were also fully liquidated.

Platt exited his Meta Platforms position entirely, a holding that had accounted for 0.06% of his portfolio since the third quarter of 2025.

He also closed out his Amazon stock, which had represented 0.7% of his overall investment portfolio since the third quarter of 2025.

Massive Bet on TSMC

While reducing exposure to these tech giants, Platt increased his stake in Taiwan Semiconductor Manufacturing by more than 430%.

His total ownership now stands at 35,824 shares, making up 0.7% of his portfolio.

The stock was originally added in the fourth quarter of 2025.

TSMC is a key player in semiconductor manufacturing, providing chips for AI and other advanced technologies.

Platt's move signals a strategic pivot toward infrastructure plays rather than direct AI leaders.

The Magnificent Seven—Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia, and Tesla—have driven the S&P 500 to a 76% gain over the past three years.

However, Platt's decision suggests he sees greater value in semiconductor manufacturing than in some of the biggest names in tech.

His portfolio adjustments were disclosed through Form 13F filings with the SEC, which are required for managers holding over $100 million in U.
