Money-Flow Trends

Biogen has seen mixed money flow activity. While retail (small) investors are showing a positive trend with an inflow ratio of 51.37%, large institutional investors have been net sellers, with block inflow at 44.32% and an overall trend described as negative.

• Small-trend: Positive, inflow ratio 51.37%
• Large-trend: Negative, inflow ratio 49.01%

This divergence between retail and institutional flows highlights a potential short-term sell-off risk, especially with large investors showing bearish behavior.
