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 strong recent performance drives the case. Revenue grew 5% year over year. The last quarter beat estimates by 78.4%. It trades at 9.8 times earnings. Peers trade at 12.6 times earnings. The price reflects less growth than we forecast. The operating income pillar is under pressure. The thesis comparison is not yet verified. Peer multiples imply a price about 39% above where it trades. Our read remains intact. This read is provisional.
Trailing returns as of 2026-11-05. 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 2026-11-05. 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.

Top 25% 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.
