Why is SML ISUZU falling/rising?

As of 15-Sep, SML ISUZU Ltd's stock price is currently at 3,748.95, reflecting an increase of 31.95, or 0.86%. The stock has shown a positive trend recently, gaining 2.25% over the last two days and outperforming its sector by 0.48% today. Despite a decline of 13.36% over the past month, the stock has demonstrated impressive year-to-date growth of 166.53% and consistent returns over the last three years, outperforming the BSE500. 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, the stock's short-term performance over the past week shows a return of 1.08%, which is slightly below the benchmark Sensex's return of 1.24%. This suggests that while SML ISUZU is experiencing a rise in price, it is not keeping pace with the overall market in the short term. However, the significant long-term gains and the recent increase in institutional investment may provide a supportive backdrop for continued interest in the stock, despite the recent decline in delivery volume and liquidity concerns.
