Why is Rail Vikas falling/rising?

As of 22-Aug, Rail Vikas Nigam Ltd is experiencing a decline in its stock price, currently at 323.80, which reflects a decrease of 4.85 points or 1.48%. The stock has underperformed its sector by 0.99% today and has been on a consecutive downward trend for the last two days, resulting in a total drop of 2.13%. Over the past week, the stock has shown a slight decline of 0.12%, and its performance over the last month has been significantly worse, with a drop of 13.00%. The company's long-term growth prospects appear poor, as evidenced by a net sales growth rate of only 6.24% and a substantial decline in pre-tax profit by 55.38%. Additionally, the stock is trading below all major moving averages, indicating a bearish trend.
In the broader market context, Rail Vikas Nigam Ltd's performance has been notably worse than the benchmark, with a year-to-date return of -23.39% compared to the Sensex's positive return of 4.05%. This underperformance is further highlighted by the fact that while the BSE500 index has seen a negative return of -2.49% over the past year, Rail Vikas has plummeted by 43.26%. The company's market capitalization of Rs 68,524 crore positions it as the largest in its sector, yet the low participation from domestic mutual funds, holding only 0.66%, suggests a lack of confidence in its current valuation and business outlook.
