Conversely, Ark trimmed holdings in Amazon ($1.1M), Alphabet ($1.1M), Robinhood, Shopify, and Block, rotating away from large-cap internet platforms and consumer-fintech stocks toward concentrated innovation themes." datetime: "2026-07-30T03:07:51.000Z" locales: - [zh-CN](https://longbridge.com/zh-CN/news/294301153.md) - [en](https://longbridge.com/en/news/294301153.md) - [zh-HK](https://longbridge.com/zh-HK/news/294301153.md) --- # Cathie Wood Keeps Buying the Dip on SpaceX, Adds $20 Million of TSMC as Chip Stocks Slide **Cathie Wood’s** **Ark Invest** leaned into some of its highest-conviction growth themes on Wednesday, July 29, led by a broad push into **Space Exploration Technologies** (NASDAQ:SPCX), **Taiwan Semiconductor Manufacturing** (NYSE:TSM), **Amazon.com** (NASDAQ:AMZN) and **Alphabet** (NASDAQ:GOOGL). The buying and selling spree came as those names sat near major news catalysts, with SpaceX facing heavy short bets, TSMC under pressure from a tech rotation and Amazon heading into an earnings watch period. ## The SpaceX Trade Ark continued accumulation of **SpaceX**, with purchases spread across **ARK Innovation ETF** (BATS:ARKK), **ARK Autonomous Technology & Robotics ETF** (BATS:ARKQ), **ARK Next Generation Internet ETF** (BATS:ARKW) and **ARK Space & Defense Innovation ETF** (BATS:ARKX). The transactions were estimated to be worth $14.5 million, based on the Elon Musk-led company’s shares closing at $112.55. The purchases come against a backdrop of rising bearish activity. Benzinga reported that SpaceX has attracted about $26 billion in short bets, with roughly 35% of the float sold short, making it one of the most heavily shorted names in the market. The report also pointed to upcoming catalysts, including earnings on Aug. 4 and a first lockup expiry two days later. On Tuesday, Wood had added $12.2 million worth of SpaceX stock. Ark has been consistently purchasing the post-IPO dip in the stock. **Read Also: Coinbase to Beat Q2 Earnings?

The total number of shares purchased was worth $20.1 million. TSM ended the day at $374.67. TSMC shares have fallen 4.88% in the past 5 days and shed nearly 7% of their value over a month. Even so, the company’s longer-term technical setup remained intact, with shares still trading above key moving averages and analysts keeping a bullish stance on the name. ## The Amazon.com Inc Trade **Amazon** was one of the notable sell-side moves in Ark’s daily trading, with ARKK trimming 4,902 shares. The transaction was valued at $1.1 million, based on the stock’s closing price of $226.65. The reduction came as investors began looking ahead to Amazon’s quarterly report, with the company still viewed as one of the most important names in cloud, e-commerce and AI spending. Benzinga’s preview on Amazon emphasized that analysts expect the company to post second-quarter revenue of $196.02 billion, with AWS remaining the key driver to watch. The story also noted that Amazon has beaten revenue estimates in seven straight quarters. ## The Alphabet Trade Alphabet was also cut by Ark, with **ARKK** selling 3,344 Class A shares worth $1.1 million. The stock ended the day at $336.71. The move adds to a broader pattern of Ark trimming exposure to large-cap internet platforms while rotating into more concentrated innovation bets elsewhere in the portfolio. Alphabet has also been in the market spotlight for another reason: Benzinga recently highlighted it as one of 2026’s most shorted stocks. That adds a layer of context to Ark’s decision to lighten up, especially with the company still facing investor debate over ad growth, AI monetization and competitive pressure. ## Other Key Trades - Ark added heavily to **Kratos Defense and Security Solutions** (KTOS). - Ark bought more **Tesla** (TSLA) with the shares purchased worth $541,152. - Ark added to **BWX Technologies** (BWXT). - Ark sold **Robinhood Markets** (HOOD), **Shopify** (SHOP) and **Block** (XYZ), trimming some of its most widely followed consumer-fintech holdings. - Ark also reduced positions in **Roblox** (RBLX), **Illumina** (ILMN), **CRISPR Therapeutics** (CRSP) and **Natera** (NTRA), continuing to pare back several volatile growth names. **Benzinga Edge Stock Rankings** indicate TSMC stock has a Growth score in the 85th percentile and a Value score in the 28th percentile. **Read Also: Meta Platforms, Qualcomm, Robinhood, Microsoft and Chipotle: Why These 5 Stock Are on Investors' Radars Today** **_Disclaimer_:** _This content was partially produced with the help of AI tools and was reviewed and published by Benzinga editors._ _Photo Courtesy: viewimage on Shutterstock.com_ ### Related Stocks -
