Why is SPARC falling/rising?

As of 01-Jul, Sun Pharma Advanced Research Company Ltd's stock price is currently at 160.95, reflecting a decrease of 1.75, or 1.08%. The stock has recently underperformed its sector by 1.3%, indicating a negative trend reversal after seven consecutive days of gains. In terms of returns, the stock has shown a decline of 13.07% over the past month and a significant drop of 33.28% over the last year, consistently underperforming against the benchmark indices. The company faces challenges such as a negative book value and weak long-term fundamental strength, with net sales and operating profit declining over the past five years. Additionally, the company's ability to service its debt is concerning, as indicated by a poor EBIT to interest ratio.
In the broader market context, the stock's short-term performance of +2.39% over the past week is better than the Sensex's return of +2.00%, suggesting some relative strength in the very short term. However, the overall trend remains negative, with the stock underperforming the benchmark over longer periods, including a 19.63% decline year-to-date compared to the Sensex's gain of 7.11%. This consistent underperformance, coupled with the company's weak financial metrics and negative EBITDA, contributes to a bearish outlook for the stock, reinforcing the perception of it being a strong sell.
