Is COHU a Buy or a Sell? The Bull and Bear Case (2026)

That depends on which case you find more convincing, and both are on this page. The bull case rests on AI and high-performance-computing ramp, with revenue (fy2025) at ~$453 million (up ~13%). The bear case rests on cohu is small and cyclical, so its orders and revenue are lumpy and swing hard with the semiconductor capital-equipment cycle and with automotive, industrial, and computing chip demand it does not control. Analysts covering it are spread from $65.00 to $80.00, which is itself a signal that this is genuinely contested. If you believe the thesis, the real questions become sizing and overlap rather than timing. Walnut is not an investment adviser and this is not a recommendation.

Nobody can answer that for you, and the honest version of the question is narrower: has anything changed in the reason you bought it? The bear case on this page is the place to check. Cohu is small and cyclical, so its orders and revenue are lumpy and swing hard with the semiconductor capital-equipment cycle and with automotive, industrial, and computing chip demand it does not control. If that risk is what you were worried about and it is now playing out, that is a real signal. If the price simply fell while the thesis held, that is a different situation entirely. The most pessimistic published target is $65.00, +27.9% from the $50.81 price, which is one analyst's downside case rather than a floor. Walnut is not an investment adviser.

AI and high-performance-computing ramp. Cohu raised its 2026 high-performance-computing revenue outlook to roughly $80 million to $100 million, led by Eclipse thermal handlers and Neon high-bandwidth-memory inspection tools, and pointed to a computing-segment pipeline it sized around $750 million in qualification and engagement. The most optimistic analyst target on COHU is $80.00, +57.4% from the $50.81 price. That figure is only reachable if this thesis works close to its best case.

Cohu is small and cyclical, so its orders and revenue are lumpy and swing hard with the semiconductor capital-equipment cycle and with automotive, industrial, and computing chip demand it does not control. It is still reporting a trailing net loss (about $39 million over the last twelve months), so the stock carries a negative trailing price-to-earnings ratio and a forward multiple near 28 that depends on the recovery continuing. After more than doubling in 2026, the shares already price in much of that recovery, and insider sales, including about $3.3 million by CEO Luis Muller in September 2026, have drawn attention. It competes against far larger, better-capitalized test-industry leaders like Teradyne, which has been expanding its AI and memory test portfolio, and Advantest, and its high-performance-computing pipeline must convert from qualification to real production orders. Customer concentration, tariff and supply-chain costs, and geopolitical or export-control exposure in Asia add further risk, and the shares tend to be volatile. The most pessimistic published target is $65.00, +27.9% from the current price, which is roughly what the stock is worth if these risks bite rather than the drivers.

Cohu, Inc., through its subsidiaries, provides semiconductor test equipment and services in the United States, Taiwan, China, Malaysia, the Philippines, Singapore, and internationally.

Decide that in advance, because it is far harder to think clearly once a position is moving against you. The concrete tripwires here: the driver behind the bull case (AI and high-performance-computing ramp) stalling in the reported numbers rather than in the narrative, the risk above (cohu is small and cyclical, so its orders and revenue are lumpy and swing hard with the semiconductor capital-equipment cycle and with automotive, industrial, and computing chip demand it does not control) turning from a possibility into a reported fact, or the position growing large enough that a bad outcome would matter to your whole portfolio regardless of who is right.

Cohu supplies test, handling, inspection, metrology, and automation equipment plus software and services to the semiconductor industry. Its tools sit in the back end of chip manufacturing, including test handlers, contactors and interface products, and inspection systems, and it also earns recurring revenue from spares, consumables, software, and services.

Not yet on a full-year GAAP basis. Over the twelve months to June 2026 Cohu posted a net loss of about $39 million, but its second quarter 2026 GAAP loss narrowed to roughly $0.2 million and non-GAAP EPS was $0.26. Its trailing price-to-earnings ratio is therefore still negative, and returning to sustained profitability depends on the 2026 revenue and margin recovery holding.

In the second quarter of 2026 (ended June 27), revenue was about $149 million, up roughly 38% from a year earlier and up from about $125 million in the first quarter. Non-GAAP EPS of $0.26 beat the $0.14 consensus. Third quarter results are scheduled for October 28, 2026, with analysts expecting about $170 million of revenue.
