Why is Rainbow Foundat. falling/rising?

As of 29-Sep, Rainbow Foundations Ltd is experiencing a decline in its stock price, currently at 90.11, reflecting a decrease of 1.83 or 1.99%. The stock has underperformed its sector by 2.7% today and has been on a downward trend for the past three days, accumulating a total loss of 5.86% during this period. Although the stock has shown impressive long-term performance with a 275.77% return over the past year, recent financial results indicate a concerning trend, including a significant drop in profit after tax and a high debt-to-equity ratio of 7.87 times, which suggests weak long-term fundamental strength. Additionally, the stock's delivery volume has fallen drastically, indicating reduced investor participation.
In the broader market context, the stock's short-term performance has been slightly better than the benchmark, with a 1-week return of -2.06% compared to the Sensex's -2.18%. Despite the stock's strong long-term performance, the recent declines highlight a divergence from the benchmark, particularly as the company faces challenges such as high debt and flat quarterly results. The market's reaction to these factors has contributed to the stock's current downward trajectory, contrasting with its historical performance against the BSE500 over longer periods.
