Immunovant Stock Dips Despite Positive Study Results: A Market Paradox
Shares of Immunovant, Inc. (NASDAQ:IMVT) experienced a 4% decline, while Roivant (NASDAQ:ROIV) saw a 2% decrease in today's trading session. This unexpected dip followed the release of positive results from their respective studies on batoclimab for Myasthenia Gravis (MG) and Chronic Inflammatory Demyelinating Polyneuropathy (CIDP), despite an initial surge of 6%.
Key Study Results
Myasthenia Gravis (MG) Study

- Significant 1.8 point improvement in the aINCAT score at week 12
