Why is Force Motors falling/rising?

As of 23-Sep, Force Motors Ltd is experiencing a decline in its stock price, currently at 18,137.75, reflecting a decrease of 49.95 points or 0.27%. The stock has underperformed its sector by 2.43% today and has been on a consecutive fall for the last four days, resulting in an overall drop of 8.61% during this period. Despite its strong long-term growth indicators, such as a 28.06% annual growth rate in net sales and a 51.42% increase in profit before tax, the stock's recent performance has been negatively impacted by falling investor participation, with delivery volume dropping by 71.1% against the five-day average. Additionally, while the stock has shown impressive returns over the past year and three years, it has recently underperformed the benchmark, with a 1-week return of -8.06% compared to the Sensex's -0.34%.
In the broader market context, the auto sector, specifically trucks, has gained by 2.22%, indicating a contrasting performance relative to Force Motors. The stock's recent struggles can be attributed to its short-term performance, which has lagged behind the benchmark, as evidenced by the significant decline in investor participation and the stock's consecutive losses. However, the increasing stake of institutional investors, who now hold 11.43% of the company, suggests a level of confidence in the company's fundamentals, which may provide some support for the stock in the long run. Overall, while the long-term outlook remains positive, the current short-term trends indicate challenges for Force Motors.
