Teradyne is trading 4.48% down now at $423.30 after broader U.S. equity weakness intensified overnight.
- The Nasdaq Composite is down 1.18%, while S&P 500 futures are down 0.55%, signaling risk-off pressure on high-growth technology shares.
- No new Teradyne announcement dated August 18 was identified; its latest major release was strong Q2 results on July 28.
- Profit-taking may be contributing after an 5.81% gain on August 17, but this is not a confirmed company-specific catalyst.
