Why is Tinna Rubber falling/rising?

As of 25-Aug, Tinna Rubber & Infrastructure Ltd's stock price is currently at Rs 830.00, reflecting a decrease of Rs 15.05 or 1.78%. The stock has underperformed today, falling after two consecutive days of gains, and it is now 3.72% away from its 52-week low of Rs 799.1. In terms of performance, the stock has shown a significant decline over the past month, down 9.98%, and a staggering 51.18% drop over the past year. Despite a high management efficiency indicated by a ROCE of 18.85% and healthy long-term growth in net sales and operating profit, the company has faced negative results recently, including a 27.18% fall in PBT and a 22.63% decline in PAT over the last nine months. Additionally, the stock's high debt-equity ratio of 0.76 times and expensive valuation compared to peers contribute to its downward pressure.
In the broader market context, Tinna Rubber's recent performance contrasts sharply with the benchmark Sensex, which has gained 0.45% over the past week. While the stock has shown a positive return of 1.03% in the last week, its longer-term performance is concerning, with a year-to-date decline of 38.14% compared to the Sensex's gain of 4.48%. This underperformance is further highlighted by the stock's significant drop relative to the BSE500 index, which has only fallen by 2.11% over the past year. The combination of falling investor participation, as indicated by a 52.81% drop in delivery volume, and the stock trading below its moving averages suggests a lack of confidence among investors, contributing to the ongoing decline in its price.
