Why is Rainbow Foundat. falling/rising?

As of 19-Aug, Rainbow Foundations Ltd is experiencing a decline in its stock price, currently at 120.40, which reflects a decrease of 2.45 or 1.99%. The stock has underperformed its sector today by 2.76% and has been on a consecutive fall for the last three days, accumulating a total decline of 5.86% during this period. Although the stock has shown impressive long-term performance with a 334.66% return over the past year, recent financial results indicate a concerning trend, including a 26% drop in profit after tax compared to the previous four-quarter average. Additionally, the company has a high debt-to-equity ratio of 5.42 times, which raises concerns about its long-term fundamental strength and profitability, as evidenced by a low return on equity of 3.24%.
In the broader market context, the stock's short-term performance contrasts sharply with the benchmark, as it has fallen by 4.06% over the past week while the Sensex has gained 1.76%. This underperformance may be attributed to falling investor participation, with delivery volume decreasing significantly by 56.95% against the five-day average. Despite the company's strong historical returns, the lack of domestic mutual fund investment, which stands at 0%, suggests a lack of confidence among institutional investors regarding the stock's current valuation and business outlook.
