Why is SPARC falling/rising?

As of 30-Jun, Sun Pharma Advanced Research Company Ltd's stock price is currently at 162.70, reflecting an increase of 1.1, or 0.68%. The stock has been gaining for the last seven days, with a total return of 8.07% during this period. However, over the past month, the stock has seen a significant decline of 12.13%, and its year-to-date performance shows a drop of 18.75%. Despite the recent gains, the company faces challenges, including a negative book value and weak long-term fundamental strength, as evidenced by a decline in net sales and operating profit over the last five years. Additionally, the stock is considered risky due to its negative EBITDA and poor ability to service debt, which may contribute to investor caution.
In the broader market context, the stock's short-term performance of +3.73% over the past week outpaces the benchmark Sensex, which has returned +2.09% in the same period. However, the stock has consistently underperformed against the benchmark over the last three years, with a one-year return of -32.25% compared to the Sensex's +5.79%. This consistent underperformance, coupled with falling investor participation and liquidity concerns, indicates that while there may be short-term gains, the long-term outlook remains challenging for Sun Pharma Advanced Research Company Ltd.
