Why is KRN Heat Exchan falling/rising?

As of 11-Sep, KRN Heat Exchanger and Refrigeration Ltd is experiencing a decline in its stock price, currently at 856.80, reflecting a decrease of 7.65 points or 0.88%. The stock's performance today is in line with the sector, although it is currently lower than the 5-day, 20-day, and 50-day moving averages, while remaining above the 100-day and 200-day moving averages. Over the past week, the stock has seen a decline of 1.36%, and over the past month, it has decreased by 1.97%. Despite this recent downturn, the company has shown strong fundamentals, including a high return on equity of 20.30%, a low debt to EBITDA ratio of 0.37, and significant growth in net sales and profit after tax for the nine-month period ending in June. Additionally, there has been an increase in institutional investor participation, which may provide some support for the stock.
In the broader market context, the Sensex has gained 1.03% over the past week and 1.17% over the past month, indicating that KRN Heat Exchanger is underperforming relative to the benchmark during these periods. This divergence suggests that while the overall market is experiencing positive momentum, KRN's recent price decline may be attributed to specific stock-related factors rather than broader market trends. The liquidity of the stock remains adequate, with a delivery volume that has increased slightly, indicating ongoing interest from investors despite the price drop.
