Why is Tinna Rubber falling/rising?

As of 11-Aug, Tinna Rubber & Infrastructure Ltd is experiencing a decline in its stock price, currently at Rs 846.10, reflecting a decrease of Rs 31.9 or 3.63%. The stock has underperformed its sector by 1.48% today, touching an intraday low of Rs 840, which represents a drop of 4.33%. Over the past week, the stock has seen a significant decline of 10.16%, and its year-to-date performance shows a staggering drop of 36.94%. Despite high management efficiency indicated by a return on capital employed (ROCE) of 18.85% and healthy long-term growth in net sales and operating profit, the stock's negative performance is compounded by disappointing financial results, including a 27.18% fall in profit before tax and a 24.05% decline in profit after tax over the last six months. Additionally, the stock's high debt-equity ratio of 0.76 times and expensive valuation relative to peers contribute to its downward trajectory.
In the broader market context, Tinna Rubber's performance has been significantly worse than the benchmark, with the Sensex only declining by 0.51% over the past week, while Tinna Rubber fell by over 10%. The stock's one-year return of -52.60% starkly contrasts with the BSE500's negative return of only -1.85%, highlighting its underperformance in the market. The rubber products sector has also faced a decline of 2.26%, further impacting investor sentiment. The falling investor participation, indicated by a 24.38% drop in delivery volume against the five-day average, suggests a lack of confidence among traders, which is likely exacerbating the stock's decline.
