When demand outruns available supply, factories run harder and pricing and margins can improve. If demand cools after companies have committed to expensive new capacity, inventory corrections, unused factories and price pressure can pull earnings down. Share prices move as investors revise expectations for those future results—not simply in step with current chip sales.
How the semiconductor cycle reaches company earnings
Chips are components inside products and systems, so orders ultimately depend on demand in markets such as data centers, computers, industrial equipment, cars and communications. A slowdown in one market can reduce orders for companies exposed to it, while another segment may remain strong. The industry is not a single, uniform demand pool.

Orders and inventory can diverge from end demand
Customers may cut new orders while using chips already on hand. That can weaken suppliers’ sales even if end users have not stopped buying altogether. Once inventories are brought closer to desired levels, orders may recover. WSTS said industrial semiconductor sales rose 5% in 2025, a sign that earlier inventory corrections and weaker capital-expenditure conditions were gradually easing (WSTS, March 6, 2026).
Capacity decisions amplify changes in demand
Building semiconductor capacity takes substantial investment and time. When demand grows faster than supply, high factory utilization can support prices and margins. But capacity planned during a boom may come online after demand has weakened, leaving equipment underused and suppliers competing more aggressively for orders. STMicroelectronics warns that the industry’s volatility makes capacity requirements difficult to predict; it identifies excess capacity, price erosion, inventory write-offs and losses as risks, while shortages can also occur (STMicroelectronics’ 2025 Form 20-F).
Pricing pressure varies by segment
Some products, notably memory, are especially exposed to swings in supply and selling prices. ASML’s 2025 annual report described memory prices at the end of 2025 as having reached levels not seen in at least a decade, amid AI demand and moderate capacity additions after the 2023 memory-market correction (ASML, 2025 annual report). That is ASML’s characterization, not an independent price index or a measure of every semiconductor category.
Why chip stocks do not simply track chip sales
Industry sales, an individual company’s earnings and a stock’s market price are related, but they are different measures. Industry sales report purchases across the market. Company earnings also depend on product mix, costs, utilization, customer concentration and the company’s role in the supply chain. A share price reflects investor expectations about future earnings, risks and valuation.
That distinction explains why a stock can fall while sales are still rising: investors may expect growth or margins to weaken. Conversely, a share price can improve before reported results recover if investors anticipate better conditions. Neither the industry figures nor the company disclosures cited here establish a fixed lead time or a numerical relationship between semiconductor stocks and the broader business cycle.

WSTS reported finalized global semiconductor sales of $795.6 billion in 2025, up 26.2% year over year. It attributed the expansion largely to logic and memory, with data-center and AI-related demand among the drivers (WSTS, March 6, 2026). This is a market-wide total, not evidence that every chip company or stock shared the same growth.
Segment differences are particularly important in the current AI-related upswing. ASML separates logic, including processors such as CPUs and GPUs, from memory, and described AI demand as supporting advanced logic and DRAM. It also noted that capacity additions after the 2023 memory correction had been moderate (ASML, 2025 annual report). Such conditions can benefit some suppliers more than others, depending on what they sell and where they sit in the production chain.
Company results illustrate why market growth cannot be applied uniformly. TSMC reported that its 2025 net revenue grew 32% in New Taiwan dollar terms and said AI-related demand was expected to remain robust entering 2026, while macroeconomic uncertainties persisted (TSMC, 2025 annual report). That is one company’s reported performance and outlook, not a forecast for every chipmaker.
WSTS’s August 2026 update also requires careful labeling: its calculation of $1,655 billion for full-year 2026 incorporated actual second-quarter data but retained the original June forecast assumptions for the third quarter and beyond. WSTS said those figures “are not new forecast values generated by WSTS under a revised scenario” (WSTS, August 2026). It is a forecast calculation, not a realized annual sales total.
For context, SIA’s February 6, 2026 release reported preliminary 2025 global sales of $791.7 billion, up 25.6%; WSTS later published its finalized total of $795.6 billion, up 26.2% (SIA, February 6, 2026; WSTS, March 6, 2026). The figures differ because they came from separate releases on different dates; use the later WSTS result when referring to finalized 2025 sales.

When comparing companies, look beyond the headline growth rate. These questions help explain why two stocks may respond differently to the same market news:
- Products and end markets: Does the company sell into AI and data centers, industrial or automotive markets, consumer devices or communications? Is it focused on logic, memory, leading-edge manufacturing or mature-node products?
- Place in the supply chain: A chip designer, integrated manufacturer, contract foundry, memory supplier and equipment vendor face different revenue drivers and capacity risks.
- Inventory and orders: What do the company’s disclosures say about customer or distributor inventories, order trends, cancellations and normalization?
- Capacity and investment: Consider utilization, fab additions, equipment orders and capital spending—and whether new supply might arrive after demand changes.
- Pricing and margins: Track selling-price direction, product scarcity, gross margins and the cost of underused capacity.
- Concentration and resilience: Assess reliance on a small number of customers, product families or regions, as well as exposure to policy-sensitive supply chains.
- Valuation and expectations: A cyclical recovery may already be reflected in a share price; strong industry news alone does not establish whether a particular stock is attractively valued.
These are analytical lenses, not a ranking or investment recommendation. The market and company disclosures above explain operating exposures but do not provide a common dataset for comparing stock valuations or returns.
