Daily closes. Earnings/event dots are placed inline.
Industries move in repeating boom-and-bust cycles. This shows where this stock’s industry sits in that cycle, stage by stage (recovery → expansion → supercycle → steady → deceleration → contraction), from its fundamentals (orders, revenue, capital spending), not the stock’s price.
A booming industry is a tailwind for the names in it; a contracting one is a headwind. Companies in the same industry tend to rise and fall together with the cycle, the way a tide lifts and lowers every boat in the harbor at once, so a large part of a stock’s swing can come from where its industry sits rather than from the company itself. It’s context for reading the company’s results, not a buy/sell call. Full explanation →
Semiconductor Materials & Equipment is in expansion. Describes the industry's cycle state, not a call on this stock.
The stage band shows the industry’s cycle over the chart’s timeline (each color a stage); a ▼ marks a quarter its growth inflected down — amber is an unconfirmed watch, red is confirmed the next quarter. Use “Overlay cycle on chart” to tint the price chart by stage. The industry’s fundamentals, not a signal on this stock.
Primary pillar under pressure — Revenue grows at least 7% per year: Q1 FY26 +15.0% vs 7.0% target.
View ThesisRevenue growth is accelerating — up about 16% over the past year.

View ManagementExpectations look reasonable — what the market is pricing in sits in line with or below what analysts forecast.
View ValuationThis stock is highly volatile — it swings about 3% on a typical day and fell roughly 48% in its worst 12-month stretch.
View RiskMKSI's growth has to keep compounding to justify the price. Revenue grew 15% year over year in Q1 FY26 and beat expectations in Q2 FY26. It trades at 24× P/E versus a peer median of 44×. The price reflects less growth than forecast, indicating modest expectations. If MKSI cuts guidance on the next call, that would be a meaningful negative. Peer multiples imply a price about 27% above where it trades. This read is provisional.
Trailing returns as of 2026-09-15. MKSI is total return (includes dividends); the S&P 500 benchmark is price return (the index excludes dividends).

Our valuation methods disagree too much on this name right now. Rather than print a number we don't believe, we're holding it back until they converge.
