Why is Onyx Biotec falling/rising?

As of 22-Sep, Onyx Biotec Ltd is currently priced at Rs 45.80, reflecting an increase of Rs 0.55 or 1.22%. Despite this positive movement today, the stock has shown a decline of 4.78% over the past week and 5.76% over the past month. It is also trading lower than its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating a bearish trend in the longer term. Furthermore, the stock is close to its 52-week low, being only 2.73% away from Rs 44.55. Notably, investor participation has significantly decreased, with delivery volume dropping by 95.97% against the 5-day average, which may contribute to the stock's recent volatility.
In the broader market context, the Sensex has increased by 0.53% over the past week and 1.34% over the past month, contrasting with Onyx Biotec's negative returns during the same periods. Year-to-date, the stock has declined by 23.03%, while the benchmark has gained 6.59%. This underperformance relative to the Sensex suggests that investor sentiment towards Onyx Biotec is weak, compounded by the falling delivery volumes and the stock's struggle to maintain momentum against its moving averages. Overall, the stock's recent rise today does not negate the broader trend of declining performance compared to the market.
