Cathie Wood Dumps the Last of Teradyne From Her Flagship Fund

Detailed summary

ARK's flagship fund exited a chip-testing stock just as it surged on a fresh Buy rating, and Wood offered no explanation. Another ARK fund still holds millions in shares, so the real question is what happens to that stake next.

Cathie Wood's ARK Innovation ETF (NYSEARCA:ARKK) sold its last Teradyne (NASDAQ:TER) shares on Wednesday, November 11, 2026. ARK's daily trade file put the sale at about $110,300 and marked it as 100% of the fund's position.

The bulk of the selling happened a day earlier. On November 10, ARK's trade file showed ARKK selling about $1.4 million of Teradyne, or 95.09% of its stake.

The stock went the other way. Teradyne rose 8.30% to $265.78 on November 11, the same day Jefferies started coverage at Buy with a $284 target. After hours, it slid 2.75% to $258.48. ARK did not say why it sold.

ARKK's November 11 holdings file listed 415 shares worth $101,841, and the final trade cleared them out.

Nothing else was disclosed. Neither Wood nor ARK posted an explanation on X or anywhere else, so any reason, including timing the rally, would be a guess.

ARK still owns Teradyne. The ARK Autonomous Technology and Robotics ETF (NYSEARCA:ARKQ) held 231,809 shares worth $56.9 million, a 3.32% weight, in its November 11 filing. At the close, that stake came to about $61.6 million.

Both ARKK sales are tiny next to a $41.49 billion market cap. They tell you about one fund's holdings and nothing about the business.

Many successful investors eventually reach the same moment. The saving is done, the portfolio is built, and the question quietly changes from how much can I grow this to how much can I take out? Get that second question wrong and decades of good investing can come apart in a handful of years.

Teradyne makes automated test equipment, the machines that check chips before they ship, and it also has a robotics unit. AI processors and high-bandwidth memory need more testing, and test's share of chip capital spending rose from 6.4% in 2025 to 8.1% for the first eight months of 2026.
