Why is Nidhi Granites falling/rising?

As of 05-Sep, Nidhi Granites Ltd's stock price is rising, currently at Rs. 309.05, reflecting an increase of 6.05 (2.0%). The stock has reached a new 52-week and all-time high today, having outperformed its sector by 0.84%. It has shown a strong performance over the last four days, gaining 7.25% during this period. Additionally, the stock has consistently outperformed the benchmark Sensex, with a remarkable 29.53% increase over the past month and an impressive 99.84% return over the last year. The company's high management efficiency, indicated by a return on equity (ROE) of 22.06%, and low debt-to-equity ratio of 0.01 times contribute positively to its valuation, despite the stock trading at a premium compared to its peers.
Broader market context indicates that while Nidhi Granites has significantly outperformed the Sensex, which has shown a 1.13% increase over the past week and no change over the past month, the overall market sentiment may be tempered by the risks associated with the company. Notably, 40.26% of promoter shares are pledged, which could exert downward pressure in a falling market. Despite these risks, the company's strong sales growth and consistent returns over the last three years have bolstered investor confidence, contributing to the stock's upward movement.
