Why is Star Delta Trans falling/rising?

As of 24-Sep, Star Delta Transformers Ltd is experiencing a decline in its stock price, currently at Rs 593.40, reflecting a decrease of Rs 7.9 or 1.31%. The stock has underperformed its sector by 0.34% today, hitting an intraday low of Rs 586.2, which is a drop of 2.51%. Additionally, the stock is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Over the past week, the stock has fallen by 6.17%, while its year-to-date performance shows a significant decline of 35.21%. Despite a long-term growth in net sales and operating profit, the stock's return over the past year is notably negative at -23.63%, indicating a struggle in maintaining investor confidence.
In the broader market context, the stock's recent performance contrasts sharply with the benchmark Sensex, which has only declined by 1.18% over the past week and has shown a positive return of 4.58% year-to-date. This underperformance is compounded by a low return on equity of 9.32%, suggesting inefficiencies in management and profitability. The company's flat results in June, with the lowest quarterly net sales and profit figures, further exacerbate concerns among investors. While the company has a low debt-to-equity ratio and a fair valuation compared to peers, the significant drop in delivery volume and overall market sentiment indicates a lack of confidence that is contributing to the stock's decline.
