TLDR
- Cathie Wood’s Ark Invest has been adding AMD and Taiwan Semiconductor Manufacturing stocks to its portfolio over recent months
- AMD shares gained 61% since Ark began adding to its position in late April, now becoming Ark’s 11th biggest holding
- Ark added approximately 800,000 AMD shares between June 17-30 across multiple ETFs
- Taiwan Semiconductor Manufacturing received over 190,000 shares added by Ark throughout June
- TSMC trades at 25 times forward earnings while AMD trades at 36 times forward earnings
Cathie Wood’s Ark Invest has been quietly building positions in two major semiconductor companies over the past several months. The investment firm has added substantial holdings in Advanced Micro Devices and Taiwan Semiconductor Manufacturing Company.
Wood’s firm began aggressively adding AMD shares in late April and continued through May. The buying accelerated between June 17 and 30, when Ark added approximately 800,000 shares of AMD.
These purchases are spread across four different Ark ETFs. The holdings appear in the Ark Autonomous Technology & Robotics ETF, Ark Next Generation Internet ETF, Ark Fintech Innovation ETF, and Ark Innovation ETF.
AMD has now become the 11th largest position in Ark Invest’s overall portfolio. The stock has performed well during this period, gaining roughly 61% since Ark began adding to its position in late April.
AMD’s Recent Performance
The chip maker’s recent gains stem from its accelerating data center business. Investors are also showing bullish anticipation for AMD’s new AI accelerators expected in the second half of this year.

Despite the strong performance, AMD still trades at approximately 36 times forward earnings. This valuation remains within the company’s typical range, though it faces competitive pressure from Nvidia in the AI chip market.
The company’s long-term prospects remain somewhat uncertain due to Nvidia’s dominant position in the chip industry. However, AMD continues to build momentum in the AI accelerator space.
Taiwan Semiconductor Manufacturing Additions
Ark complemented its AMD purchases with exposure to Taiwan Semiconductor Manufacturing in May. The firm doubled down on this decision by adding over 190,000 shares of TSMC throughout June.

TSMC operates differently from other chip companies like Nvidia or AMD. Rather than designing its own chipsets, the company provides industry-leading fabrication services that bring semiconductor designs to life.
This unique position allows TSMC to benefit from rising AI infrastructure spending regardless of which specific chipsets see the most demand. The company essentially provides the manufacturing backbone for the entire semiconductor industry.
TSMC’s Market Position
Investors in TSMC don’t need to analyze which chip company will sell the most graphics processing units. An investment in TSMC functions similarly to a broader bet on ongoing data center infrastructure and AI chip investment.
The company trades at 25 times forward earnings, which appears reasonable despite some valuation expansion during the AI revolution. TSMC’s valuation contrasts favorably with AMD’s higher multiple.
Geopolitical tensions with China create some uncertainty around TSMC’s growth prospects. However, the company continues investing in geographic expansion to address these concerns.
TSMC’s strong institutional backing and industry-leading fabrication position support its long-term outlook. The company maintains compelling secular tailwinds in the AI chip manufacturing space.
Ark’s recent additions to both AMD and TSMC positions occurred during June 2025, with the firm continuing to build exposure to semiconductor manufacturing and AI chip companies.
