Why is Deepak Nitrite falling/rising?

As of 17-Sep, Deepak Nitrite Ltd. is experiencing a price increase, currently at 1,844.00, reflecting a rise of 54.95 or 3.07%. The stock has shown a positive trend recently, gaining 5.61% over the last two days and outperforming its sector by 2.08%. Despite a mixed performance over longer periods, with a year-to-date decline of 26.12% and a one-year return of -36.61%, the stock's recent upward movement is supported by a significant increase in delivery volume, which rose by 335.08% compared to the five-day average. Additionally, the company boasts a high return on equity (ROE) of 22.90% and a low debt-to-equity ratio of 0.04, which may enhance investor confidence.
In the broader market context, the stock's short-term performance of +6.07% over the past week significantly outpaces the Sensex, which has only increased by 1.56% in the same timeframe. However, the stock has consistently underperformed against benchmarks over the longer term, particularly with a three-year return of -12.53% compared to the Sensex's +40.54%. This underperformance, coupled with negative financial results reported in June, including a 40.1% drop in profit before tax, raises concerns about the company's long-term growth potential, despite the recent positive price movement.
