Why is Ruby Mills falling/rising?

As of 07-Jul, Ruby Mills Ltd. is experiencing a price increase, currently at 250.00, reflecting a rise of 4.0 or 1.63%. The stock has shown strong performance recently, outperforming its sector by 2.29% today and achieving a consecutive gain over the last two days with a total return of 2.04%. Additionally, Ruby Mills has outperformed the benchmark Sensex over the past week with a return of 3.16% compared to the Sensex's decline of 0.20%. However, despite this positive short-term momentum, the company faces challenges such as weak long-term fundamental strength, indicated by a low Return on Capital Employed (ROCE) of 5.15% and stagnant growth in net sales and operating profit over the past five years. Furthermore, domestic mutual funds hold no stake in the company, which may reflect a lack of confidence in its valuation or business prospects.
In the broader market context, Ruby Mills' recent gains contrast with the Sensex's performance, which has shown a modest increase of 1.53% over the past month. While Ruby Mills has demonstrated a significant return of 14.26% over the same period, its year-to-date performance remains negative at -3.12%, indicating potential volatility. The stock's liquidity is adequate, with a delivery volume increase, suggesting rising investor participation. However, the company's flat results and reliance on non-operating income for profit may raise concerns about its sustainability, which could impact future price movements.
