The stock traded lower early in the week, dipping to $213.58 on Monday (31 Aug), before turning higher. Wednesday (2 Sep) brought a volume surge of 1.27m shares and a push to $225.80, followed by a close at $224.51 on Thursday (3 Sep) and a slight pullback to $220.83 on Friday (4 Sep). Weekly amplitude came to 5.65%, while average daily volume of 0.78m shares ran about 17% below the 60-day median, making this a relatively quiet up week. ## Key Events The week was driven by Leqembi and Zorevunersen updates. On Tuesday (1 Sep), Canada’s Drug Agency issued a final positive recommendation supporting public reimbursement of Leqembi. The same day, Biogen shared four-year Zorevunersen data pointing to potential disease-modifying effects. On Thursday (3 Sep), Biogen and Eisai announced China approval for subcutaneous LEQEMBI in early Alzheimer’s disease. Also on Thursday, Stoke Therapeutics and Biogen presented long-term Zorevunersen clinical data at the 16th European Epilepsy Congress, supporting its disease-modifying potential in Dravet syndrome. Filings showed one material item on Friday (4 Sep), a routine disclosure with no further business detail in this week’s news. ## Analyst Ratings Among the 35 institutions covering Biogen, 20 rate it buy, 3 overweight, 11 hold and 1 sell, giving 23 buy or overweight ratings in total. The consensus rating is buy, with a consensus target of $236.87, about 7.3% above the current price of $220.83. Targets range from $165.00 to $300.00, a wide spread. Biogen ranks first by analyst rating among 507 biotech companies. ## The Week Ahead US macro data dominates next week: NFIB small business optimism on Tuesday (8 Sep) with a prior reading of 99.8, followed on Thursday (10 Sep) by initial jobless claims (prior 206), final demand PPI, core final demand PPI, existing home sales annual rate, wholesale sales and EIA natural gas storage. Biogen has no earnings on the calendar, though follow-through on China approval for Leqembi and further interpretation of Zorevunersen data are worth tracking. ## In Short Biogen’s outperformance this week was accompanied by Leqembi reimbursement and China approval development, as well as Zorevunersen data supporting an R&D narrative. Analyst ratings lean constructive: consensus buy and an industry rank of first, but the target range is wide and the latest session showed retail as the main net buyer, with no large-lot net inflow. At about 39x P/E and 1.73x P/B, valuation sits in the historical middle. The question ahead is whether pipeline and regulatory progress convert into commercial results, and how next week’s macro figures affect risk appetite for biotech. *This article is generated by LongbridgeAI from market data, for information only and not investment advice.* ### Related Stocks - [BIIB.US](https://longbridge.com/en/quote/BIIB.US.md) ## Related News & Research - [Biogen And Eisai Announce China Approval For Subcutaneous LEQEMBI To Treat Early Alzheimer's Disease](https://longbridge.com/en/news/297867394.md) - [Biogen: 4-year Data Support Potential Disease-modifying Effects Of Zorevunersen](https://longbridge.com/en/news/297656275.md) - [Biogen platforms lupus patient advocate in social media push](https://longbridge.com/en/news/297335137.md) - [Why Veeva Systems (VEEV) Is Up 11.6% After Strong Q2, Higher Guidance, and New AI CRM Wins](https://longbridge.com/en/news/297419205.md) - [Biogen CEO Viehbacher to speak at Morgan Stanley Global Healthcare Conference](https://longbridge.com/en/news/297227566.md) --- > **Disclaimer: This article is for reference only and does not constitute any investment advice.**
