Why is Action Const.Eq. falling/rising?

As of 16-Sep, Action Construction Equipment Ltd's stock price is currently at 1,110.35, reflecting a decrease of 14.2 points or 1.26%. The stock has underperformed its sector by 1.43% today, following a trend reversal after two consecutive days of gains. Additionally, the stock's delivery volume has significantly decreased by 66.91% compared to the 5-day average, indicating falling investor participation. Over the past week, the stock has declined by 3.05%, while it has shown a positive return of 19.08% over the past month. However, the stock has a concerning year-to-date return of -26.27% and a one-year return of -15.93%, which is notably worse than the broader market performance.
In the broader market context, the Sensex has gained 1.58% over the past week and 2.21% over the past month, contrasting sharply with Action Construction Equipment Ltd's recent performance. The company's low debt-to-equity ratio and healthy long-term growth in net sales and operating profit are positive factors; however, flat results in the latest quarter, including a significant drop in net sales and the lowest debtor turnover ratio, raise concerns. The stock's high valuation, as indicated by its price-to-book value, and the minimal stake held by domestic mutual funds suggest a lack of confidence in the current price. Overall, the combination of negative short-term performance and broader market gains contributes to the stock's current decline.
