Who bought and sold, at what price, and how much of their own holding it was — from SEC Form 4, UK PDMR and EEA MAR Article 19 notifications, with each insider's last-reported position and disclosed major holders.

Valuation

No valuation model yet for Biogen

A valuation is produced by the company research pipelines — the flash thesis carries one, and a deep dive replaces it with a fuller model. Neither has run for this company yet.

Public comps (how the market prices the nearest comparable businesses)

The 6 investable Drug Manufacturers - General industry peers closest in size, largest first. Market caps are shown in USD so the set compares like with like; the multiples are currency-neutral. The median is taken across the PEERS only — it is what this company is being compared to — and per column, over the peers that actually report each measure.

A comparable set says what the market is paying for similar businesses today, not what any of them is worth. It is a cross-check on the model above, not a substitute for it.

Technicals

Interactive price chart with the common technical-analysis overlays and indicators — moving averages, Bollinger Bands, volume, RSI and MACD — plus an at-a-glance momentum summary. Use the chart's own toolbar to add or remove studies, change timeframe, or search a different listing.

A note on method: PrimerIQ's research is built bottom-up from the filings — what a business earns and what it's worth. The charts below read price history, not the business; we include them because many investors want them, not because they drive our valuation. Treat them as one lens among several.
