Why is SML ISUZU falling/rising?

As of 18-Sep, SML ISUZU Ltd's stock price is currently at Rs 3,670.00, reflecting a decline of Rs 102.35 or 2.71%. The stock has been underperforming, having fallen consecutively for the last two days, resulting in a total decrease of 3.47% during this period. Today's trading saw the stock touch an intraday low of Rs 3,640, with a weighted average price indicating more volume was traded closer to this low. Additionally, the stock's delivery volume has decreased significantly, falling by 35.17% compared to the five-day average, suggesting reduced investor participation. Despite these short-term challenges, SML ISUZU has shown impressive long-term growth, with net sales increasing at an annual rate of 28.56% and operating profit at 32.21%. Institutional investors have also increased their stake, indicating confidence in the company's fundamentals.
In the broader market context, SML ISUZU's short-term performance has lagged behind the benchmark Sensex, which has gained 1.80% over the past week while SML ISUZU has only increased by 0.10%. The stock's year-to-date return of 160.91% significantly outpaces the Sensex's 6.24%, highlighting its strong long-term performance. However, the recent decline may be attributed to the stock's inability to maintain momentum in the face of declining trading volume and investor participation. While the company has consistently generated positive returns over the last three years, the current market sentiment appears to be weighing on the stock's price.
