Why is DE Nora India falling/rising?

As of 29-Jul, DE Nora India Ltd's stock price is currently at 920.30, reflecting an increase of 35.3, or 3.99%. The stock has shown a strong performance today, outperforming its sector by 2.87% and reaching an intraday high of Rs 939.2, which is a 6.12% increase. Despite a recent 1-week decline of 2.51%, the stock has gained 6.39% over the past month. The company has reported significant growth in its quarterly profits, with a profit before tax (PBT) increase of 2398.3% and a profit after tax (PAT) growth of 233.2% compared to the previous four-quarter average. However, it is important to note that the stock has underperformed in the long term, with a staggering 45.96% decline over the past year, indicating a concerning trend despite recent positive quarterly results.
In the broader market context, DE Nora India Ltd's recent performance contrasts with the benchmark Sensex, which has decreased by only 1.03% over the past week and has shown a positive return of 4.09% year-to-date. This underperformance highlights the stock's volatility and the risks associated with its historical valuations, particularly given its negative EBITDA and a significant drop in operating profit over the last five years. While the stock has seen increased investor participation and liquidity, the long-term outlook remains uncertain due to its substantial decline in profits and overall negative returns compared to the market.
