Why is GNFC falling/rising?

As of 18-Jul, Gujarat Narmada Valley Fertilizers & Chemicals Ltd. is experiencing a decline in its stock price, currently at 545.00, reflecting a decrease of 1.1 or 0.2%. The stock has been underperforming recently, having fallen consecutively for the last three days with a total return of -1.14% during this period. Despite outperforming its sector by 0.95% today, the stock's delivery volume has decreased by 24.82% compared to the five-day average, indicating a drop in investor participation. Over the past week, the stock has shown a modest increase of 1.12%, but it has a year-to-date return of -2.11% and a significant decline of 19.83% over the past year, despite a rise in profits by 20.1%. The company maintains a fair valuation with a low debt-to-equity ratio and high institutional holdings at 23.17%, which may provide some support against further declines.
In the broader market context, the stock's recent performance contrasts with the Sensex, which has seen a decline of 0.90% over the past week. While GNFC has outperformed the benchmark in the short term, its year-to-date performance lags behind the Sensex's gain of 4.63%. This disparity suggests that while the stock may have some positive fundamentals, such as a high dividend yield of 3.02% and strong operating profit margins, the overall market sentiment and recent trading activity are contributing to its downward price movement.
