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.
Primary pillar broken — Sufficient liquidity to fund operations through year-end 2026: TTM OCF -$3.1M vs target: positive liquidity through 2026.
View ThesisRevenue is contracting — down about 97% over the past year.
View GrowthManagement screens strong on the balance sheet, market reaction to earnings.
View ManagementExpectations look high — what the market is pricing in runs ahead of what analysts forecast.
View ValuationThis stock is highly volatile — it swings about 3% on a typical day and fell roughly 77% in its worst 12-month stretch.
View RiskATRA's growth has to keep compounding to justify the price. Recent financial performance dropped from the robust 65th to the 17th percentile of its sector. Revenue grew 8.6% year over year, and the last quarter beat expectations. ATRA trades at 23× price-to-sales versus an 11.9× peer median, indicating the market is pricing in more growth than we forecast. Our model puts the next-quarter miss near 48%, which is elevated. The primary pillar has broken, as sufficient liquidity to fund operations through year-end 2026 is not assured. Peer multiples imply a price about 52% below where it trades. This read is provisional.
