Why is Pokarna falling/rising?

As of 03-Sep, Pokarna Ltd is experiencing a decline in its stock price, currently at Rs 829.35, reflecting a decrease of Rs 19.8 or 2.33%. The stock has been underperforming, having fallen for the last six consecutive days, resulting in a total decline of 13.06% during this period. Additionally, it has underperformed its sector by 3.1% today. The stock's performance over the past week shows a significant drop of 11.13%, while its year-to-date return is down by 28.84%. Despite a high management efficiency indicated by a ROCE of 17.04% and healthy long-term growth in net sales and operating profit, the recent flat quarterly results have negatively impacted investor sentiment.
In the broader market context, the Sensex has only decreased by 0.27% over the past week, indicating that Pokarna's decline is more pronounced than the overall market trend. While the stock has shown strong performance over the long term, with a 51.92% increase over three years and a remarkable 513.65% rise over five years, the recent quarterly results, including a 14.4% drop in PAT and the lowest net sales recorded, have raised concerns among investors. This has likely contributed to the stock's current downward trajectory, despite the presence of high institutional holdings and a favorable PEG ratio of 0.2, suggesting that the stock is undervalued compared to its earnings growth.
