Why is Shiva Texyarn falling/rising?

As of 19-Sep, Shiva Texyarn Ltd's stock price is currently at 189.00, reflecting an increase of 2.8, or 1.5%. Today's performance indicates that the stock has outperformed its sector by 1.3%. However, despite this positive movement, the stock has shown a decline of 1.02% over the past week, while it has gained 3.85% over the last month. The company has reported positive results for the last four consecutive quarters, with a significant growth in PAT and net sales. Nevertheless, the stock's long-term fundamentals are weak, indicated by a low average ROCE and poor growth rates in net sales and operating profit over the past five years.
In the broader market context, the Sensex has increased by 0.88% over the past week, suggesting that while Shiva Texyarn has outperformed its sector today, its recent weekly performance lags behind the benchmark. The stock's liquidity remains adequate for trading, but there has been a notable decline in investor participation, with delivery volume dropping significantly. This decline in participation, combined with the company's high debt to EBITDA ratio, raises concerns about its long-term growth potential, which could be contributing to the stock's volatility despite recent positive quarterly results.
