Why is Ruby Mills falling/rising?

As of 08-Jul, Ruby Mills Ltd. is experiencing a price increase, currently at Rs 251.90, reflecting a rise of 1.9 (0.76%). The stock has shown a positive trend recently, gaining 2.82% over the past week and 15.13% over the past month. Despite this upward movement, the stock has underperformed its sector by 1.07% today, and while it has been gaining for the last three days, the delivery volume has decreased by 9.78% compared to the five-day average. Additionally, the stock is trading above its moving averages across various time frames, indicating a short-term bullish trend. However, the company faces challenges, including weak long-term fundamental strength with a low return on capital employed and poor growth in net sales and operating profit over the last five years.
In the broader market context, Ruby Mills' recent performance contrasts with the Sensex, which has only increased by 0.02% over the past week. Although the stock has shown a strong return of 2.92% over the past year, its profits have declined by 5.2%, and domestic mutual funds hold no stake in the company, suggesting a lack of confidence among institutional investors. This combination of short-term gains alongside long-term concerns may contribute to the stock's volatility and mixed investor sentiment.
