Why is SPARC falling/rising?

As of 27-Jun, Sun Pharma Advanced Research Company Ltd's stock price is currently at Rs 161.60, reflecting an increase of Rs 2.0 or 1.25%. The stock has been on an upward trend, gaining for the last six days and achieving a total return of 7.34% during this period. Despite this recent performance, the stock has shown a decline of 19.30% year-to-date and a significant drop of 33.99% over the past year, indicating a consistent underperformance against the benchmark. Additionally, the stock's delivery volume has decreased by 70.97% compared to the five-day average, suggesting a decline in investor participation. The company is facing challenges with a negative book value and weak long-term fundamentals, as evidenced by declining net sales and operating profit over the last five years.
In the broader market context, the stock has outperformed the sector by 0.37% today, while the benchmark Sensex has risen by 2.00% over the past week. However, the stock's performance remains concerning when viewed over longer periods, as it has underperformed the benchmark in each of the last three years. The stock's liquidity is adequate for trading, but the overall negative sentiment surrounding its financial health, including a poor EBIT to interest ratio and negative EBITDA, continues to weigh heavily on investor confidence.
