Why is Tainwala Chem. falling/rising?

As of 04-Aug, Tainwala Chemicals & Plastics (India) Ltd is experiencing a significant rise in its stock price, currently at Rs 268.00, reflecting an increase of Rs 35.85 or 15.44%. Today's price performance indicates that the stock has outperformed its sector by 14.45%, opening with a gain of 2.2% and reaching an intraday high of Rs 268. The stock has shown strong returns over various periods, including a 9.39% increase over the past week and a remarkable 209.65% over the last three years. The company recently declared positive results after two consecutive negative quarters, with net sales growing by 90.75% in the latest six months and a notable profit before tax of Rs 0.46 crore. However, there are concerns regarding long-term fundamental strength, as indicated by a low return on equity of 3.31% and a weak EBIT to interest ratio.
In the broader market context, Tainwala Chemicals has significantly outperformed the benchmark Sensex, which has only increased by 0.16% over the past week and declined by 2.89% over the past month. While the stock has generated an 18.87% return over the last year, the Sensex has only seen a marginal increase of 0.05% in the same period. Despite the positive short-term performance, the stock's long-term growth prospects appear weak, with a low annual growth rate in net sales and a high price-to-earnings growth (PEG) ratio of 22.3, suggesting that while the stock is rising now, there are underlying concerns that could affect its future performance.
