Why is Tinna Rubber falling/rising?

As of 25-Sep, Tinna Rubber & Infrastructure Ltd's stock price is currently at Rs 935.00, reflecting a decline of Rs 42.75 or 4.37%. The stock has been underperforming, having fallen consecutively for the last two days, resulting in a total drop of 5.16% during this period. In terms of returns, the stock has shown a strong performance over the past week and month, with increases of 15.05% and 12.65%, respectively. However, it has significantly underperformed over the year, with a decline of 40.71%. The company has a high management efficiency indicated by a return on capital employed (ROCE) of 18.85%, but it also faces challenges such as a high debt-equity ratio of 0.76 and negative profit trends, including a 27.18% drop in profit before tax.
In the broader market context, Tinna Rubber's performance contrasts sharply with the benchmark Sensex, which has experienced a slight decline of 2.23% over the past week. Despite the stock's recent short-term gains, its long-term performance remains concerning, as it has underperformed the market significantly over the last year. The stock's valuation appears expensive relative to its peers, and while it has shown healthy growth in net sales and operating profit, the overall negative sentiment from recent financial results and falling investor participation could be contributing to its current price decline.
