Why is SML ISUZU falling/rising?

As of 28-Aug, SML ISUZU Ltd's stock price is currently at Rs 4,282.15, reflecting a decrease of Rs 191.05 or 4.27%. The stock has been underperforming recently, having fallen consecutively for the last two days with a total decline of 8.54%. Today's trading saw the stock reach an intraday low of Rs 4,269, and it has underperformed its sector by 2.55%. Despite a strong long-term growth trajectory, with net sales and operating profit showing significant annual increases, the recent price movement indicates a decline in investor participation, as evidenced by a 19.41% drop in delivery volume compared to the five-day average. Institutional investors have increased their stake, which may provide some support, but the current trend suggests a lack of momentum.
In the broader market context, SML ISUZU's short-term performance over the past week shows a decline of 2.85%, which is worse than the Sensex's drop of 2.34%. However, the stock has demonstrated remarkable long-term performance, with a year-to-date increase of 204.43% compared to the Sensex's modest 2.48%. This stark contrast highlights that while the stock has historically outperformed the market, recent short-term pressures and declining investor interest may be contributing to its current price drop.
