Why is SML ISUZU falling/rising?

As of 02-Sep, SML ISUZU Ltd's stock price is currently at 3,939.95, reflecting a decrease of 144.7 points or 3.54%. The stock has been underperforming, having fallen for the last five consecutive days, resulting in a total decline of 15.85% during this period. Today's trading saw the stock touch an intraday low of Rs 3,880.45, and it has exhibited high volatility with an intraday volatility of 5.35%. Despite a healthy long-term growth outlook, with net sales growing at an annual rate of 28.56% and operating profit at 32.21%, the recent price movement has been negatively impacted by falling investor participation, as evidenced by a 28.98% 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 1-week return of -11.92% compared to the Sensex's decline of only -0.78%. While the stock has shown impressive long-term returns, including a 180.10% increase year-to-date and consistent outperformance over the last three years, the recent downturn suggests that short-term pressures, such as declining investor interest and high volatility, are currently overshadowing its positive fundamentals.
