Why is SML ISUZU falling/rising?

As of 26-Aug, SML ISUZU Ltd's stock price is currently at Rs 4,473.20, reflecting a decrease of Rs 208.8, or 4.46%. The stock has recently underperformed its sector by 4.09% and has experienced a trend reversal, falling after four consecutive days of gains. It touched an intraday low of Rs 4,460.45, indicating a decline of 4.73%. Despite this drop, the stock has shown strong performance over longer periods, with a year-to-date increase of 218.02% and a three-year return of 538.98%. Positive factors contributing to the stock's long-term growth include a healthy annual growth rate in net sales of 28.56% and an operating profit increase of 32.21%. Additionally, institutional investors have raised their stake in the company, which may provide a stabilizing effect on the stock.
In the broader market context, SML ISUZU's recent performance contrasts with the Sensex, which has declined by 1.05% over the past week. The stock's short-term performance has been significantly better than the benchmark, with a 1-week return of 11.89% compared to the Sensex's decline. However, the recent drop in investor participation, with delivery volume falling by 19.82% against the 5-day average, may indicate waning interest, contributing to the stock's current decline. Overall, while the stock has demonstrated strong long-term growth and institutional support, recent price movements suggest a temporary setback amid changing market dynamics.
