Why is SML ISUZU falling/rising?

As of 09-Sep, SML ISUZU Ltd's stock price is currently at Rs 3,679.00, reflecting a decrease of Rs 29.8 or 0.8%. The stock has been underperforming recently, having fallen consecutively for the last four days, resulting in a total decline of 6.95% during this period. Today, it opened with a loss of 2% and reached an intraday low of Rs 3,634.8. Despite this, the stock has shown strong long-term growth, with a year-to-date increase of 161.55% and a remarkable 368.27% rise over the past three years. Positive factors include healthy net sales growth and increased institutional investor participation, which may support the stock's fundamentals despite its recent price decline.
In the broader market context, SML ISUZU's short-term performance has been notably weaker compared to the benchmark Sensex, which has gained 1.18% over the past week while SML ISUZU has dropped 6.62%. This stark contrast indicates that while the company has strong long-term prospects, its recent price movements are not aligning with the overall market trend. The stock's liquidity remains adequate, and the increasing participation from institutional investors suggests a level of confidence in its long-term potential, even as it faces short-term challenges.
