Why is SPARC falling/rising?

As of 04-Jul, Sun Pharma Advanced Research Company Ltd's stock price is currently at 159.20, reflecting a decrease of 0.2, or 0.13%. The stock has been underperforming, having fallen consecutively for the last four days, resulting in a total decline of 2.15% during this period. In terms of returns, the stock has seen a significant drop of 34.50% over the past year, and it has consistently underperformed against the benchmark, the BSE500, in each of the last three annual periods. Additionally, the company has a negative book value and weak long-term fundamental strength, with net sales and operating profit declining over the last five years. The stock's liquidity appears adequate, but investor participation has decreased, as evidenced by a 31.9% drop in delivery volume compared to the five-day average.
In the broader market context, the stock's short-term performance has been notably worse than the benchmark, with a 1-week return of -1.49% compared to the Sensex's -0.74%. While the stock has shown a slight increase of 1.37% over the past month, this is overshadowed by its year-to-date decline of 20.50%, contrasting sharply with the Sensex's gain of 6.77% during the same period. The overall market sentiment appears to be unfavorable for SPARC, compounded by its weak financial metrics and the risk associated with its negative EBITDA, which further contributes to its declining stock price.
