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 →
Semiconductors is in supercycle. 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.
The reason to own it still holds.
View ThesisThis stock is volatile — it swings about 3% on a typical day and fell roughly 39% in its worst 12-month stretch.
View RiskUMC depends on sales growth and expansion spending to strengthen its product capabilities. The desk records no earnings history or latest release to confirm that growth. August sales increased 30%, and expansion funding supports future product capabilities. No valuation multiple or priced-in assessment is available to define what price reflects. Our model puts the next-quarter miss near 12%, though the watch tier is quiet. Our read remains intact, but this read is provisional.

A consensus fair price across 0 valuation methods, at three horizons. As of 2026-10-23. Estimates are diagnostics, not price targets. Short-horizon estimates are close to coin-flips, so confidence is a method-agreement read, not a prediction.
Today's peer multiple on trailing earnings, with no growth credited. This is the headline read.
Adds projected growth, so it leans optimistic by design. Read it as upside context, not a base case.
A price-focused, side-by-side fair-value read versus Semiconductors — fair value, gap to price, and forward P/E.
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.
