Why is SML ISUZU falling/rising?

As of 30-Jul, SML ISUZU Ltd's stock is currently priced at 3,377.20, reflecting a decline of 71.15 points or 2.06%. The stock has been on a downward trend, having fallen consecutively for the last five days, resulting in a significant 16.36% decrease over that period. Today's trading saw the stock open with a loss of 2.7%, reaching an intraday low of Rs 3,305.5, while the weighted average price indicates more volume was traded closer to this low. Despite a strong long-term growth trajectory, with net sales and operating profit showing healthy annual growth rates, the recent performance has been negatively impacted by falling investor participation, as evidenced by a 79.8% drop in delivery volume compared to the five-day average.
In the broader market context, SML ISUZU's recent performance contrasts sharply with the benchmark, as it has underperformed the Sensex, which declined by only 1.50% over the same one-week period. However, the stock has shown impressive returns over the longer term, with a year-to-date increase of 140.10% and a three-year return of 372.47%. The increase in institutional investor participation, which has risen by 0.75% in the last quarter, suggests a level of confidence in the company's fundamentals, potentially providing some support against the recent price decline. Nonetheless, the current short-term volatility and declining trading volume indicate that the stock is facing challenges in maintaining its upward momentum.
