Cathie Wood, CEO of ARK Invest known as "Mama Cathie," recently pointed out in an interview that the artificial intelligence (AI) field is currently dominated by the "Big Four": OpenAI, Anthropic, Elon Musk's xAI, and Google's (GOOGL.US) Gemini. She added that competition among these four companies is becoming increasingly fierce. "In the large language model (LLM) space, the number of truly competitive companies has decreased." Against this backdrop, Wood is doubling down on AI, cloud computing, and next-generation internet sectors, particularly focusing on Chinese technology stocks.

Here are the major trading activities of her actively managed funds last week:

**ARK Innovation ETF (ARKK.US):**

**Sell Operations:** - Continued reducing positions in streaming device maker Roku (ROKU.US), selling approximately 68,000 shares worth over $6.5 million. Based on cumulative reduction scale, ARK Invest is gradually lowering its exposure to this American TV streaming audio-video player manufacturer. - Reduced holdings in medical technology company Tempus AI (TEM.US) by over 107,000 shares, valued at more than $8 million. - Trimmed AMD (AMD.US) position by approximately 138,000 shares, worth about $22 million. - Simultaneously reduced gaming platform Roblox (RBLX.US) by over 38,000 shares, valued at $5 million.

**Buy Operations:** - Increased holdings in clinical-stage gene editing company Intellia Therapeutics (NTLA.US) by approximately 120,000 shares, worth about $1.96 million last week. During the same period, the company's stock price rose about 5%. - First purchase of Alibaba (BABA.US) since 2021, buying approximately 63,000 shares worth about $11 million. - Simultaneously entered the Chinese search engine market by purchasing about 82,000 shares of Baidu (BIDU.US), also valued at approximately $11 million.

Notably, ARK Innovation ETF has gained nearly 45% year-to-date, significantly outperforming the S&P 500's 12.9% gain over the same period. This renewed positioning in Alibaba and Baidu signals that ARK Invest is viewing the Chinese market as a new opportunity, particularly focusing on AI, cloud computing, and next-generation internet sectors.
