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 RiskMostly healthy — no soft spokes
Biogen's growth in its Alzheimer's treatment portfolio must continue to justify its current valuation. Revenue grew 3% year over year, and the company beat earnings expectations by 356% in the latest quarter. It trades at 13× P/E, which is below the peer median of 20×, indicating that the price reflects less growth than forecasted. A specific risk is the potential for a credibility hit if Biogen were to cut guidance after recently raising it, which our model puts at a 12% miss probability. Peer multiples imply a price about 12% above where it trades. This read is provisional.
