Why is Grindwell Norton falling/rising?

As of 18-Aug, Grindwell Norton Ltd. is currently priced at 1,478.80, reflecting an increase of 9.8 (0.67%). The stock has shown a trend reversal, gaining after three consecutive days of decline, and reached an intraday high of Rs 1501.9, which is a 2.24% increase. However, it has underperformed its sector by 1.07% today and is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Over the past week, the stock has decreased by 0.72%, and it has significantly underperformed the benchmark over the last month and year, with returns of -16.92% and -39.73%, respectively. Despite high management efficiency indicated by a return on equity (ROE) of 18.29% and a low debt-to-equity ratio, the stock's long-term growth prospects appear poor, with net sales growing at only 14.94% annually over the last five years and a high valuation relative to its peers.
In the broader market context, the Sensex has increased by 0.83% over the past week, contrasting with Grindwell Norton’s decline. This indicates that while the overall market is experiencing positive momentum, Grindwell Norton is struggling to keep pace. The company's consistent underperformance against the benchmark over the last three years, coupled with a significant drop in profits and flat results in recent quarters, suggests that investor sentiment may be cautious. Additionally, a decrease in delivery volume indicates falling investor participation, which could further pressure the stock's price in the near term.
