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 →
Pharmaceuticals 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 — Operating income improvement through cost control: Comparison needs review.
View ThesisRevenue is growing steadily — about 1% over the past year.
View GrowthManagement screens strong on capital allocation, margins, the balance sheet.
View ManagementExpectations look reasonable — what the market is pricing in sits in line with or below what analysts forecast.
View ValuationThis stock is volatile — it swings about 2% on a typical day and fell roughly 43% in its worst 12-month stretch.
View RiskAMPH’s appeal rests on strong recent performance and an above-sector earnings yield, despite mixed earnings quality. Revenue grew 5% year over year in Q2 FY2026, after non-GAAP earnings missed in Q1. Q2 non-GAAP earnings beat consensus by 78.4%. AMPH trades at 9.8× P/E versus a 16× peer median; its own historical multiple is 8×. The price reflects less growth than our forecast. The specific risk is operating-income improvement through cost control; that comparison needs review. Peer multiples imply a price about 44% above where it trades. The thesis is on watch; this read is provisional.
Trailing returns as of 2026-10-29. AMPH is total return (includes dividends); the S&P 500 benchmark is price return (the index excludes dividends).

A consensus fair price across 10 valuation methods, at three horizons. As of 2026-10-29. 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 Pharmaceuticals — 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.

Above average on quality vs scored peers
A second lens on the 12-month fair value: for companies that score high on measured quality (profitability, balance-sheet safety, earnings stability), this read trusts more of today's profit margins instead of averaging them toward their multi-year history the way the headline number does. Shown alongside the fair value above, not in place of it. A diagnostic, not a price target or a buy/sell signal.
