Why is Dolphin Offshore falling/rising?

As of 26-Sep, Dolphin Offshore Enterprises (India) Ltd is experiencing a decline in its stock price, currently at Rs 378.00, which reflects a decrease of Rs 15.2 or 3.87%. The stock has underperformed today, opening with a loss of 2.39% and reaching an intraday low of Rs 369, marking a 6.15% drop. Over the past week, the stock has decreased by 5.78%, and it has shown a significant decline of 14.48% over the past month. Despite the company reporting strong growth in net sales and operating profit, it suffers from poor management efficiency indicated by a low Return on Capital Employed (ROCE) of 8.93%, and falling participation from institutional investors, which has contributed to its recent price movement.
In the broader market context, Dolphin Offshore's performance contrasts with the Sensex, which has only declined by 2.66% over the past week. The stock's year-to-date performance is particularly concerning, with a drop of 34.60%, while the benchmark has gained 2.93%. This underperformance is compounded by a significant decrease in delivery volume, which fell by 38.67% against the 5-day average, indicating waning investor interest. The company's high valuation relative to its earnings, coupled with a negative sentiment from institutional investors, further exacerbates the stock's challenges in the current market environment.
