On the reaction day the stock moved 1.7 pts less than Nifty Microcap 250 and 3.1 pts less than its Other Financial Services peers, over the same two closes: a difference in percentage points, not a measure of what the filing did.
Minute windows have no benchmark: there is no intraday index history to compare against.
Non-promoter shareholder Rama Shiva Lease Finance sold 42,583,333 Biogen shares, equal to 4.04 percent of voting capital, through the open market on 16 October 2026. Its holding fell from 4.04 percent to zero, with no pledges or other voting rights reported.
The seller has fully exited. The completed 4.04 percent sale may weigh on sentiment but does not involve a promoter stake change.
