Why is NACL Industries falling/rising?

As of 31-Jul, NACL Industries Ltd is experiencing a price increase, currently at Rs 321.60, which reflects a rise of Rs 15.3 or 5.0%. The stock has shown strong performance recently, gaining 17.59% over the last three days and outperforming its sector by 6.03% today. It is also trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating positive momentum. Additionally, institutional investors have increased their stake in the company, suggesting confidence in its potential despite some underlying weaknesses, such as a significant decline in operating profits over the past five years.
In the broader market context, NACL Industries has outperformed the Sensex significantly, with a 1-month return of +40.41% compared to the benchmark's -3.00%. This trend of strong stock performance is further highlighted by its year-to-date return of +381.87% against the Sensex's +3.90%. However, the stock's rising price comes amidst concerns regarding its long-term fundamental strength, including a high Debt to EBITDA ratio and negative EBITDA, which may pose risks for future performance. Despite these challenges, the stock's recent gains reflect a combination of positive institutional interest and strong short-term returns relative to the market.
