The largest buy came from the ARK Genomic Revolution ETF (ARKG), which purchased 17,134 shares of Genedx Holdings (WGS), valued at roughly $2 million. Genedx is a genetic testing company that uses advanced DNA sequencing to help detect rare diseases. The buy signals ARK’s growing interest in firms that turn genomic data into clinical answers.

Wood Trims Stakes in Quantum-Si and Brera Holdings

On the sell side, ARKG sold 498,068 shares of semiconductor-based life sciences company Quantum-Si Inc. (QSI), worth about $1.3 million. The company, known for its protein sequencing technology, has seen its stock under pressure amid slower adoption trends.

At the same time, the ARK Innovation ETF (ARKK) made a minor adjustment, selling 202 shares of Brera Holdings (SLMT), a digital assets firm, for about $2,900. Though small, the trade extends ARK’s steady reduction in the stock over the past week. Brera, which formerly traded under the ticker BREA, changed its symbol to SLMT on October 3, 2025.
