Over the past week, the stock has decreased by 4.69%, and it has seen a year-to-date decline of 23.11%.

In the broader market context, Onyx Biotec's performance has been notably weaker compared to the Sensex, which has gained 1.67% over the past week and 7.52% year-to-date. This stark contrast highlights the stock's struggles in a generally positive market environment. The liquidity of the stock is sufficient for trading, but the overall negative returns and underperformance against the benchmark suggest that investor sentiment remains cautious or bearish regarding Onyx Biotec's prospects.
