Why is Jamna Auto Inds. falling/rising?

As of 26-Aug, Jamna Auto Industries Ltd is experiencing a decline in its stock price, currently at Rs 100.80, which reflects a decrease of Rs 2.1 or 2.04%. Today's performance indicates that the stock has underperformed its sector by 1.23% and has fallen after two consecutive days of gains. The stock touched an intraday low of Rs 100.5, marking a drop of 2.33%. Over the past week, the stock has decreased by 2.04%, while it has shown a positive return of 7.77% over the past month. However, the stock's performance over the last year has been poor, with a decline of 19.42%. Despite a high management efficiency indicated by a return on equity (ROE) of 19.10% and a low debt-to-equity ratio of 0.10, the stock's profits have fallen by 12.9% over the past year, contributing to its recent price movement.
In the broader market context, the stock's short-term decline of 2.04% over the past week contrasts with the benchmark Sensex, which has only fallen by 1.05% during the same period. This underperformance suggests that investor sentiment towards Jamna Auto Industries Ltd may be weakening, particularly as indicated by a significant drop in delivery volume, which fell by 64.04% compared to the 5-day average. While the stock remains liquid enough for trading, the combination of declining investor participation and recent profit reductions may be influencing the stock's downward trajectory, despite its attractive valuation relative to peers.
