Why is Elegant Marbles falling/rising?

As of 18-Sep, Elegant Marbles and Grani Industries Ltd is experiencing a price increase, currently at Rs 233.50, reflecting a rise of Rs 3.5 or 1.52%. The stock has outperformed its sector today by 2.28%, despite touching an intraday low of Rs 225.1 earlier in the day. Over the past week, the stock has shown a return of +4.71%, while its one-month return stands at +5.44%. Although the stock has a negative year-to-date return of -10.93%, it is trading at a fair value compared to its peers, with a Price to Book Value of 0.6. However, the company has a weak long-term fundamental strength, indicated by an average Return on Equity (ROE) of 2.82% and flat results in net sales growth.
In the broader market context, the stock's short-term performance has significantly outpaced the Sensex, which has only increased by 1.80% over the past week. This suggests that investor sentiment may be improving for Elegant Marbles despite its overall negative returns in the longer term. The rising investor participation, evidenced by a 103.21% increase in delivery volume, indicates growing interest in the stock, which may be contributing to its recent price rise. However, the company's weak long-term fundamentals and declining sales growth could pose risks to sustained upward movement in its stock price.
