Unusual options — attention, not intent
TER appeared in a UOA top-30 list on 1 of 62 archived scanner sessions: 1 call-side, 0 put-side and 0 on both lists. The latest session did not place it in either top 30. Its larger composite score was -0.07, below the 1.5 “strong” threshold. That is options attention, not proof of bullish trade initiation.

Open TER Financials →How TER trades — the working manual
Teradyne supplies automated test equipment for semiconductors and electronics and owns collaborative and mobile-robotics businesses. For the stock, rising chip complexity can increase test intensity, but customer capital cycles, product timing and robotics execution determine whether that structural demand becomes smooth revenue and margin growth.
What can move the tape
- 01Semiconductor-test demand across compute, memory, wireless, automotive and industrial markets.
- 02Test intensity, new-device ramps and share on high-complexity customer programs.
- 03Utilization and capital spending at major semiconductor customers and outsourced test providers.
- 04Robotics growth, segment profitability, research investment and free-cash-flow conversion.
What can fool the read
- 01Semiconductor capital spending can fall sharply when utilization or end demand weakens.
- 02Customer concentration and program timing can create large quarter-to-quarter swings.
- 03A delayed tester or interface transition can shift revenue across periods or lose share.
- 04Robotics investments can dilute margins if industrial adoption grows more slowly than expected.
Teradyne triggered 4 issuer-level flags in the committed 2026-04-01–2026-08-21 archive. The latest was TER on 2026-06-25: 1.5× its 30-day average volume while the stock moved +4.0% that session.
Not published yet. The local archive has 1 reported TER events—too few for a defensible gap-and-drift study. This missing block is an explicit indexing blocker.

TER stock questions
Is TER stock in an uptrend?+
TER is classified in the “split trend” regime as of 2026-08-21: the close is -2.7% from its 50-day average and +22.2% from its 200-day average. This describes the current tape. It is not a forecast.
What does unusual options activity in TER mean?+
Teradyne's OTM option chain produced an outlier relative to the scanner universe on at least one archived session. Call-side and put-side labels identify which book produced the signature; end-of-day chain data does not identify buyers, sellers, institutions or spread legs.
Are the TER 13F holdings current?+
No. 13F filings are delayed quarter-end snapshots and cover only the curated managers in this project. They are useful for documented ownership changes, not real-time positioning or complete institutional ownership.
Where are TER's income statement and cash flow?+
The dedicated TER Financials page contains the full quarterly and annual income statement, balance sheet and cash-flow history parsed from SEC EDGAR XBRL. This stock page carries only the latest filed snapshot.
Why is there no TER earnings-move base rate yet?+
The committed earnings archive does not yet contain enough reported events for a defensible company-level reaction study. The page leaves that block unpublished instead of presenting a tiny sample as a reliable base rate.
