A boom can tighten supply and lift utilization and margins; later, new capacity may arrive just as demand cools, leaving companies with excess inventory, weaker prices and underused factories. Stocks move as investors revise expectations about those future results—not simply in step with current chip sales or the economy.
How the semiconductor cycle works
Chips are components in products and systems sold into computing, data centers, industrial equipment, cars, communications and consumer electronics. When customers expect stronger sales, they may order more chips. When end demand slows, they may cut orders or use chips already on hand. Those changes can affect suppliers before the change is fully visible in reported semiconductor sales.
Customer inventories can magnify a slowdown
A customer that has more chips than it needs may reduce new orders while selling or using its existing stock. That order cut can be larger or arrive sooner than the change in end-user demand. Once inventories are brought closer to desired levels, orders may recover. WSTS reported that industrial semiconductor sales grew 5% in 2025 and said this suggested earlier inventory corrections and weaker capital-expenditure conditions were gradually easing (WSTS, March 6, 2026).
Capacity takes time and money to change
Manufacturing capacity is expensive and cannot be adjusted as quickly as orders. If demand outpaces supply, factories can run more fully and constrained supply may support prices and margins. Companies may then invest in more capacity. If that capacity becomes available after demand has weakened, suppliers can face underused facilities, price competition and inventory write-offs. STMicroelectronics identifies excess-capacity charges, price erosion, inventory write-offs and losses among the risks arising from industry volatility; it also notes that shortages can occur (STMicroelectronics, 2025 Form 20-F).

Prices and margins do not move equally across chip types
Some products, particularly memory, can experience pronounced price swings. ASML said memory prices at the end of 2025 had risen to levels not seen in at least a decade, in a market shaped by AI demand and moderate capacity additions following the 2023 memory correction. That is ASML’s characterization in its annual report, not an independent price index (ASML, 2025 annual report).
Why a growing industry can still have a downcycle
Long-run growth and short-run cycles can coexist. More computing, data-center infrastructure and connected devices may increase the long-term need for chips, while customer order timing, inventory adjustments and capacity investment still create periods of scarcity and surplus. Growth in the total market does not mean each product category or supplier grows at the same rate.
Finalized WSTS figures show that global semiconductor sales reached $795.6 billion in 2025, up 26.2% from 2024. WSTS attributed the expansion to strength led by logic and memory and cited data-center and AI-related demand (WSTS, March 6, 2026). This is an industry sales total, not a measure of every company’s earnings or any stock’s return. WSTS also reported the industrial segment’s more modest 5% growth, illustrating how a strong overall result can conceal different conditions across end markets.
AI-related demand has been an important source of strength, but it is not a guarantee that every chip business is in the same phase. ASML describes AI demand supporting advanced logic and DRAM, while the pace and type of capacity customers add affect equipment suppliers differently from chipmakers (ASML, 2025 annual report). TSMC said AI-related demand was expected to remain robust entering 2026 while macroeconomic uncertainties persisted; that is the company’s outlook, not a certain outcome (TSMC, 2025 annual report).
How operating cycles reach stock prices
Industry sales, a company’s earnings and its share price are related, but they are not interchangeable. Industry sales measure purchases across the market. Company earnings also depend on its products, costs, capacity use, pricing, investment and customers. A stock price reflects investors’ expectations about future earnings, risks and valuation.
That difference helps explain why a semiconductor share can fall while reported sales are still rising: investors may expect growth, prices or margins to weaken from current levels. A share can also rise before reported results recover if investors anticipate that inventory corrections are ending or demand is improving. Neither direction follows mechanically from the latest market-sales number.
The sources cited here document industry conditions and company-specific operating risks, not a quantified relationship between semiconductor stock returns and the business cycle. They do not establish a universal lead or lag, a stock-market beta, or a rule that chip shares always outperform or underperform in a recession. Cyclicality alone therefore cannot show whether a particular share is cheap or expensive.

Companies can experience the same broad market cycle very differently. Before comparing two chip-related stocks, consider:
- Products and end markets: AI and data-center exposure differs from industrial, automotive, communications or consumer exposure. Logic, memory, leading-edge products and mature-node products can face different demand and pricing conditions.
- Place in the supply chain: Designers, integrated manufacturers, contract foundries, memory suppliers and equipment makers have different revenue drivers and exposure to fab investment.
- Inventory and orders: Look for disclosed customer or distributor inventories, order trends, cancellations and management commentary about normalization.
- Capacity and spending: Utilization, planned fabs, capital expenditure and equipment orders help show whether supply may remain tight or catch up after demand changes.
- Pricing, margins and concentration: Selling-price trends, underused-capacity costs and reliance on a few customers, products or regions affect resilience.
- Expectations in the valuation: A cyclical recovery may already be reflected in a share price. A positive industry headline alone does not establish that a security is attractively valued.
Read current market figures with their dates and status
Fast-moving semiconductor forecasts should not be confused with realized annual sales. WSTS’s finalized 2025 result was $795.6 billion, up 26.2%, released March 6, 2026. An earlier SIA release on February 6, 2026, reported $791.7 billion and 25.6% growth for 2025; those are figures from separate releases at different dates, not interchangeable totals (SIA, February 6, 2026; WSTS, March 6, 2026).
WSTS’s August 2026 update calculated a 2026 full-year market figure of $1,655 billion using actual Q2 data, but retained its original June forecast assumptions for Q3 and beyond. WSTS explicitly said the update was not a new forecast scenario. It is therefore a forecast calculation, not a realized full-year total (WSTS, August 2026 release).
