Why is Raj Rayon Inds. falling/rising?

As of 12-Aug, Raj Rayon Industries Ltd is experiencing a decline in its stock price, currently at 26.40, which reflects a decrease of 0.19 or 0.71%. The stock has been losing value for the last two days, with a total drop of 2.69% during this period. Despite positive results over the last three consecutive quarters, including a significant growth in profit after tax and net sales, the stock's performance in the short term has been underwhelming, as indicated by its recent returns of -0.94% over the past week and -0.83% over the past month. Additionally, the stock's delivery volume has decreased significantly, falling by 52.15% compared to the five-day average, which suggests a decline in investor participation.
In the broader market context, the stock's recent performance contrasts with the benchmark, as it has underperformed the Sensex, which has seen a decline of 0.59% over the past week. While Raj Rayon Industries has outperformed the market over the longer term, with a year-to-date return of 13.40% compared to the Sensex's 2.68%, the current weak long-term fundamental strength, indicated by a low return on capital employed and high debt-to-EBITDA ratio, raises concerns among investors. Furthermore, the lack of domestic mutual fund investment may signal a lack of confidence in the stock's valuation, contributing to its recent price decline.
