The sale of shares by a significant investor like Deerfield Partners could be seen as a negative signal by the market, potentially leading to a short-term negative impact on NYXH's stock price. However, since the stake is still below a very significant level (e.g., 5% or 10%), and the reduction is relatively small, the impact may be limited. The confidence level is not at the maximum because the market's reaction to such notifications can be unpredictable and may also be influenced by other concurrent market factors.
