Why is SML ISUZU falling/rising?

As of 16-Sep, SML ISUZU Ltd's stock is rising, with a current price of 3,801.75, reflecting an increase of 52.8 points or 1.41%. The stock has shown a positive trend, gaining for the last three days and achieving a total return of 3.69% during this period. Despite a recent decline of 12.14% over the past month, the stock has demonstrated impressive long-term performance, with a year-to-date increase of 170.28% and a remarkable 380.41% rise over the past three years. Positive factors contributing to this upward movement include a healthy long-term growth rate in net sales and operating profit, as well as increased participation from institutional investors, who now hold 16.02% of the company, indicating confidence in its fundamentals.
In the broader market context, SML ISUZU's short-term performance of +3.34% over the past week significantly outpaces the Sensex, which has only increased by 1.58% during the same period. This outperformance highlights the stock's resilience and appeal to investors, particularly in light of its consistent returns over the last three years, where it has outperformed the BSE500. However, it is worth noting that there has been a decline in investor participation, with delivery volume falling by 31.07% against the five-day average, which could suggest caution among some retail investors despite the stock's positive trajectory.
