Why is SML ISUZU falling/rising?

As of 01-Sep, SML ISUZU Ltd's stock price is currently at 4,084.65, reflecting a decline of 117.3 points or 2.79%. The stock has been underperforming, having fallen for four consecutive days with a total drop of 12.94% during this period. Today's trading saw the stock reach an intraday low of Rs 4011, and the volume traded was closer to this low price, indicating a lack of strong buying interest. Despite a strong long-term growth outlook, with net sales and operating profit showing significant annual increases, the recent performance has been negatively impacted by falling investor participation, as evidenced by a 45.08% drop in delivery volume compared to the five-day average.
In the broader market context, SML ISUZU's short-term performance has significantly lagged behind the benchmark, with a 12.76% decline over the past week compared to a 1.56% drop in the Sensex. While the stock has shown impressive returns over the longer term, including a 190.39% increase year-to-date, the recent downturn suggests that short-term pressures are outweighing these positive long-term fundamentals. The increased stake by institutional investors may provide some support, but the current market sentiment appears to be cautious, contributing to the stock's recent price decline.
