Put SPTX beside peers and holdings, graph the same metric, and keep your notes with the evidence.
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 →
Biotechnology is in steady. 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 42% in its worst 12-month stretch.
View RiskSPTX’s case depends on earnings recovering after its latest reported loss. The desk provides no revenue trajectory, and the latest quarter reported GAAP EPS of -1.78. No clean valuation multiple is available, and the desk says price roughly matches forecast growth. Our model puts next-quarter miss probability near 68%, following a very large recent miss. Peer multiples imply a price about 64% above where it trades. Our read remains intact, but this read is provisional.

A consensus fair price across 1 valuation methods, at three horizons. As of 2026-10-16. 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 Biotechnology — fair value, gap to price, and forward P/E.
