Why is Ruby Mills falling/rising?

As of 14-Jul, Ruby Mills Ltd. is experiencing a price increase, currently at Rs 240.55, reflecting a rise of 3.1 (1.31%). Today's price summary indicates that the stock has outperformed its sector by 1.83% and has gained after two consecutive days of decline, reaching an intraday high of Rs 243. However, despite this short-term gain, the stock has shown a negative return of -3.78% over the past week and a year-to-date decline of -6.78%. The company's long-term fundamentals are weak, with a low average Return on Capital Employed (ROCE) of 5.15% and poor growth in net sales and operating profit over the last five years. Additionally, the stock's valuation appears expensive relative to its ROCE, and domestic mutual funds hold no stake in the company, suggesting a lack of confidence in its prospects.
In the broader market context, while Ruby Mills has outperformed the Sensex by 1.83% today, its one-week performance is notably worse than the benchmark, which has only declined by -1.42%. The stock's recent upward movement may be a temporary rebound amidst a generally weak performance, as indicated by the significant drop in investor participation, with delivery volume falling by 45.65% against the five-day average. This suggests that while there may be short-term optimism reflected in today's price increase, the overall market sentiment and the company's long-term outlook remain concerning.
