Why is Tinna Rubber falling/rising?

As of 19-Sep, Tinna Rubber & Infrastructure Ltd's stock price is currently at Rs 825.00, reflecting an increase of Rs 12.3, or 1.51%. The stock has shown a trend reversal by gaining after three consecutive days of decline, opening with a gain of 2.25% today and reaching an intraday high of Rs 845.5. However, it remains 3.93% away from its 52-week low and has underperformed its sector by 0.84%. Over the past year, the stock has significantly underperformed, with a return of -48.11%, while its net sales and operating profit have shown healthy long-term growth rates of 36.16% and 97.28%, respectively. Despite high management efficiency indicated by a ROCE of 18.85%, the stock's valuation appears expensive with a high debt-equity ratio of 0.76 times and a decline in profits by 10.1% over the past year.
In the broader market context, Tinna Rubber's short-term performance is slightly better than the benchmark Sensex, which has returned 0.88% over the past week compared to the stock's 0.86%. However, the stock has significantly lagged behind the market in the longer term, with a year-to-date return of -38.51% versus the Sensex's gain of 5.74%. The rubber products sector has gained by 2.4%, indicating a positive trend in the industry, yet Tinna Rubber's falling investor participation, as evidenced by a 47.17% drop in delivery volume, suggests a lack of confidence among investors. Overall, while there are some positive indicators for Tinna Rubber, the significant underperformance and high valuation concerns contribute to a cautious outlook for the stock.
