Hook and thesis
Cohu has been one of 2026's semiconductor standouts, rallying from a $18 low last year to trade near $67 today. The market has been front-running a rapid reacceleration in chip test demand driven by AI and memory segmentation. My read: the fundamentals are starting to catch up with the rally - revenue growth is real, margins are beginning to expand, and cash generation is positive. That combination supports a tactical long into what should be better reported results and continued order flow.
In short: this is a trade that leans on revenue and margin momentum more than multiple compression. We want to own the name for a defined period - mid term - while protecting capital with a clear stop and a realistic upside target tied to recent price action and the 52-week high.
What Cohu does and why the market should care
Cohu provides back-end semiconductor test and handling equipment, interface products, and related services. Its customers are semiconductor fabs and electronic manufacturers that need validation and test infrastructure for logic, memory and increasingly AI-focused chips. Test equipment is a classic capex-driven segment - orders are lumpy but follow broad cycles in semiconductor investment.
Why this matters now: AI and data-center chips have pushed test complexity and spending higher. That push benefits vendors who can deliver high-throughput, high-bandwidth test solutions. Cohu has been one of the beneficiaries, with public commentary and order wins referenced across its recent communications and analyst notes. The market rewards companies that can convert that demand into sustainable revenue and expanding gross margins.
What the numbers say
Concrete metrics that back the bullish case:
- Market cap sits near $3.17 billion while enterprise value is approximately $3.25 billion.
- Recent quarterly revenue prints showed meaningful growth - a Q4 report cited revenue of $122.2 million, up 30% year-over-year, and management projected steady revenue into the following quarter with gross margins improving toward ~45%.
- Price-to-sales is elevated at 6.07 and EV-to-sales is about 6.22, reflecting the multiple expansion the stock has already seen.
- Profitability remains a transition story: the latest reported EPS was negative at about -$0.82, but free cash flow is positive at roughly $34.9 million, supporting the view that operations are generating cash as volumes scale.
- Balance sheet metrics are conservative: debt-to-equity is modest at 0.38, and liquidity ratios are strong - current ratio ~5.74 and quick ratio ~4.72.
Valuation framing
At a market cap of ~$3.17 billion and EV/sales north of 6x, Cohu is priced like a growth name. That multiple looks aggressive relative to historical cyclical norms for semiconductor equipment, but the premium reflects forward-looking expectations: sustained double-digit revenue growth and margin recovery. The stock has already rerated; the key question for traders is whether the company can deliver the margin expansion and cash conversion priced in.
Two points of nuance: first, EPS is still negative which means investors are paying for revenue and margin improvement rather than current earnings. Second, free cash flow of roughly $35 million mitigates some valuation risk since the company is not purely burning cash while it scales.
Technical backdrop and positioning
Momentum indicators are constructive: the 10-day and 20-day SMAs sit well below the current market price, the 9-day EMA is near $60.92, and MACD readings show bullish momentum. RSI at ~67.6 signals above-average buyer interest but is not yet deeply overbought. Short interest remains material - recent settlement data show roughly 8.6 million shares short with days-to-cover around 8.6, implying the stock can be volatile on news and can experience squeezes if fundamentals surprise to the upside.
Trade plan (actionable)
Position: Long COHU
Entry price: 67.03
Stop loss: 60.00
Target: 78.00
Horizon: mid term (45 trading days). Rationale - this time window gives the market a chance to digest follow-through on recent order momentum and early margin improvements, while keeping exposure limited to the next cycle of reported results and order announcements.
Trade sizing should reflect the elevated valuation and operational execution risk. For discretionary traders a 2-4% portfolio allocation is reasonable; active traders may scale in on weak intraday prints and trim into strength near the target.
Catalysts to move the stock higher
- Stronger-than-expected quarter: revenue beats and clear sequential margin improvement toward the guided ~45% would validate the rally.
- Large design wins or multi-million-dollar orders in AI test platforms, which can be referenced in press releases or earnings calls.
- Analyst upgrades and price target raises from coverage that currently favors wafer-fab and AI-related test suppliers.
- Progress on the HBM product ramp - management previously flagged $15-20 million potential HBM revenue for the year; faster ramp would be a direct earnings lever.
Risks and counterarguments
Anyone taking this trade needs to balance upside with material risks.
- Valuation is already rich. With price-to-sales ~6x and EV/sales ~6.2x, the stock trades like a high-growth winner. If revenue growth slows or margins disappoint, multiple compression could be swift.
- Earnings still negative. EPS is roughly -$0.82; while cash flow is positive, continued negative EPS leaves little room for execution missteps.
- Cyclicality and lumpy bookings. Semiconductor test demand is cyclical and order flows can be volatile. A downgrade to end-market demand or a postponed capex cycle could pressure backlog and revenue timing.
- Insider selling and profit taking. Recent filings show insiders monetizing shares - the CEO executed a pre-planned sale of 55,794 shares for about $3.3 million on 09/21/2026 and a director sold shares earlier. While these were positioned as orderly sales, they can increase near-term supply and prompt profit-taking from other holders.
- High short interest and potential volatility. Days-to-cover near 8.6 suggests sharp moves on both beats and misses; traders should be prepared for outsized intraday swings.
Counterargument: The main bear case is that Cohu's rerating has already priced in sustained AI-led capex and margin expansion. If the market reverts to discounting cyclical tech names, or if alternative suppliers (Teradyne, KLA) win disproportionate wallet share, Cohu could see a multi-point decline. That said, free cash flow and an improving gross margin trajectory give the company a better foundation than a pure momentum story.

What would change my mind
I will reassess the bullish stance if any of the following occurs:
- Management signals a material demand slowdown or pushes out key AI-related orders in its next earnings call.
- Gross margins fail to show sequential improvement toward the mid-40s as previously guided, or guidance turns meaningfully cautious.
- Free cash flow turns negative or the balance sheet weakens through elevated debt financing.
Conclusion
Cohu is a trade, not a sure thing. The stock already reflects a lot of optimism, but there are tangible reasons to believe the fundamentals can catch up: double-digit revenue growth, improving margins, and positive free cash flow. For traders willing to accept valuation and execution risk, a mid-term (45 trading days) long with an entry near $67.03, a stop at $60.00, and a target of $78.00 offers a defined risk-reward that aligns with the company's visible catalysts. Keep position sizes disciplined and watch the next earnings and order announcements closely - they will be the real test of whether earnings finally catch up with the rally.
