Why is SML ISUZU falling/rising?

As of 04-Aug, SML ISUZU Ltd's stock price is currently at Rs 3,514.70, reflecting an increase of Rs 43.4 or 1.25%. The stock has shown a positive trend recently, gaining 6.37% over the last two days, and opened with a gain of 3.13% today. Despite this upward movement, the stock has underperformed its sector by 0.58%. Over the past week, the stock has declined by 3.17%, but it has significantly outperformed the benchmark with a year-to-date return of 149.87% compared to the Sensex's 3.69%. Positive factors contributing to the stock's rise include healthy long-term growth in net sales and operating profit, as well as increased participation from institutional investors, who now hold 16.02% of the company.
Broader Market Context: In the short term, SML ISUZU's performance has been less favorable compared to the benchmark, as it has underperformed the Sensex over the past week. However, the stock's strong long-term returns, including a 63.42% increase over the past year and a remarkable 409.08% rise over the last three years, indicate robust investor confidence and consistent performance. While the stock has experienced a recent decline in delivery volume, the overall liquidity remains sufficient for trading, suggesting that investor interest may still be present despite the short-term fluctuations.
