Why is Valiant Laborato falling/rising?

As of 28-Jul, Valiant Laboratories Ltd is experiencing a decline in its stock price, currently at Rs 89.70, which reflects a decrease of Rs 5.3 or 5.58%. The stock has underperformed its sector by 5.66% today and has been on a downward trend, falling for the last two days with a total return drop of 8.24%. Over the past week, the stock has decreased by 8.52%, and in the last month, it has seen a significant decline of 22.24%. The company's recent financial performance shows a mixed picture; while it reported positive results in March with a higher profit after tax and net sales, it also faces serious long-term challenges, including a negative EBITDA and a poor return on equity of 0%. The stock's liquidity is also concerning, with a 70.53% drop in delivery volume compared to the five-day average.
In the broader market context, Valiant Laboratories' performance has been notably worse than the benchmark Sensex, which has only declined by 1.59% over the past week and 3.77% over the past month. The stock's long-term performance is troubling, with a staggering 34.62% drop in the past year, contrasting sharply with the Sensex's slight decline of 0.54% in the same period. This underperformance, combined with weak fundamentals and a lack of confidence from domestic mutual funds, suggests that investors are wary of the company's future prospects, contributing to the ongoing decline in its stock price.
