Why is Deepak Nitrite falling/rising?

As of 23-Sep, Deepak Nitrite Ltd. is experiencing a price increase, currently at Rs 1,821.95, reflecting a rise of 10.7 points or 0.59%. The stock has shown a positive performance today, outperforming its sector by 1.15% and gaining for the last two consecutive days with a total return of 0.98% in that period. However, it is still close to its 52-week low, being only 4.9% away from Rs 1,732.7. Despite a high management efficiency indicated by a return on equity (ROE) of 22.90% and a low debt-to-equity ratio of 0.04, the company has faced challenges with poor long-term growth, as evidenced by a -1.05% annual growth rate in operating profit over the last five years and significant declines in profit before tax and profit after tax in the most recent quarter.
In the broader market context, Deepak Nitrite's short-term return of +1.84% over the past week contrasts with the Sensex, which has declined by -0.34% during the same period. However, the stock has underperformed against the benchmark over the longer term, with a -36.52% return over the past year compared to the Sensex's -3.33%. This consistent underperformance, coupled with falling investor participation and a high valuation relative to peers, suggests that while there may be short-term gains, the stock's long-term outlook remains concerning, contributing to its mixed performance in the market.
