Why is NCC falling/rising?

As of 22-Sep, NCC Ltd's stock price is currently at 213.90, reflecting a decrease of 3.0 points or 1.38%. Today's price summary indicates that the stock has underperformed its sector by 0.33%, and it has experienced a trend reversal, falling after two consecutive days of gains. The stock's performance over the past week shows a slight increase of 0.85%, but it has declined by 1.50% over the past month and has a year-to-date drop of 22.06%. Despite a healthy long-term growth rate in net sales and operating profit, the stock has generated a significant negative return of 32.25% over the past year, which is much worse than the broader market's decline of 2.82%. Additionally, the stock's delivery volume has decreased by 32.17% compared to the five-day average, indicating falling investor participation.
In the broader market context, while the Sensex has shown a positive return of 0.46% over the past week, NCC Ltd's recent performance contrasts sharply with this benchmark. The stock's underperformance is further highlighted by its negative returns over one month and year-to-date periods, which are significantly worse than the market averages. Although the company maintains a low debt-to-equity ratio and has seen an increase in institutional holdings, these factors have not been sufficient to counterbalance the negative sentiment surrounding its recent financial results, which included flat net sales and declines in profit before tax and profit after tax compared to previous quarters.
