Why is Suven Life Scie. falling/rising?

As of 11-Jun, Suven Life Sciences Ltd is experiencing a significant rise in its stock price, currently at Rs 247.30, reflecting an increase of Rs 22.45 or 9.98%. The stock has shown strong performance, gaining 11.75% over the last three days and outperforming its sector by 9.12%. Additionally, it has delivered impressive returns over various periods, including a 143.21% increase over the past year and a staggering 656.27% over the last five years. However, despite this positive momentum, the company faces challenges, including operating losses and a weak long-term fundamental strength, as evidenced by a -49.94% annual growth rate in net sales over the past five years and negative EBITDA.
In the broader market context, Suven Life Sciences Ltd's recent performance has outpaced the benchmark Sensex, which has only increased by 1.87% over the past week and 3.85% over the last month. While the stock's short-term gains are notable, the decline in institutional investor participation, with a -1.13% reduction in their stake, raises concerns about the stock's sustainability. The company's negative results over the last three quarters and weak ability to service its debt further complicate its outlook, suggesting that while the stock is rising now, underlying fundamental issues could pose risks in the future.
