Should I Buy Biogen Inc. Stock?
Biogen Inc is a good buy right now due to its current price of $218.5, which is below the analyst price targets of $260 and $300, indicating significant upside potential. Additionally, the company has a solid forward P/E ratio of 18.45, suggesting reasonable valuation relative to expected earnings growth. The recent launch of LEQEMBI IQLIK, a new Alzheimer's treatment, is expected to enhance revenue, contributing to a projected 22.88% year-to-date change in stock price. However, insider selling has increased by 864.10% over the last month, which is a notable risk factor.
