Why is Shiva Texyarn falling/rising?

As of 12-Sep, Shiva Texyarn Ltd's stock price is currently at Rs 190.95, reflecting an increase of Rs 6.15 or 3.33%. The stock has shown a strong performance today, outperforming its sector by 3.91% and reaching an intraday high of Rs 190.95. Over the past week, the stock has risen by 4.32%, and it has also demonstrated a notable increase of 10.99% over the past month. The company has reported positive financial results for the last four consecutive quarters, with net sales growing by 28.13% and profit after tax increasing by 32.97%. Despite this, the stock has a negative year-to-date return of -12.02% and a one-year return of -9.89%, indicating some underlying weaknesses. The stock is trading at a discount compared to its peers, which may attract investors, but it also faces concerns regarding its long-term fundamental strength, as indicated by a low return on capital employed and high debt levels.
In the broader market context, the Sensex has increased by 1.48% over the past week and 2.08% over the past month, suggesting that while Shiva Texyarn has outperformed the benchmark in the short term, it has lagged behind in the longer term, with a three-year return of +16.90% compared to the Sensex's +36.25%. This disparity highlights the stock's recent volatility and the challenges it faces in maintaining investor confidence. The rising investor participation, as evidenced by a 13.89% increase in delivery volume, may indicate growing interest, but the overall negative returns over the past year and the company's high debt to EBITDA ratio raise concerns about its sustainability in the market.
