Why is SPARC falling/rising?

As of 18-Jul, Sun Pharma Advanced Research Company Ltd's stock price is currently at 161.25, reflecting a decrease of 0.2, or 0.12%. The stock has been experiencing a decline, having fallen consecutively for the last two days with a total return of -1.16% during this period. Despite outperforming its sector by 0.43% today, the stock has shown significant underperformance over the longer term, with a year-to-date decline of 19.48% and a one-year return of -30.16%. The company faces challenges, including a negative book value and weak long-term fundamental strength, as evidenced by a poor EBIT to Interest ratio and declining net sales and operating profit over the past five years.
In the broader market context, the stock's short-term performance contrasts with the benchmark, as it has gained 1.13% over the past week while the Sensex has decreased by 0.90%. However, the stock's long-term trajectory remains concerning, with a consistent underperformance against the benchmark over the last three years. The liquidity of the stock appears adequate, with a notable increase in delivery volume, but the overall financial health and negative EBITDA suggest that investors may remain cautious, contributing to the stock's recent price decline.
