Why is SML ISUZU falling/rising?

As of 28-Jul, SML ISUZU Ltd's stock price is currently at Rs 3,629.80, reflecting a decline of Rs 191.0, or 5.0%. The stock has been underperforming recently, having fallen for three consecutive days, resulting in a total drop of 10.11% during this period. It opened the day with a loss of 4.86% and reached an intraday low of Rs 3,629.80. Despite a strong performance over the past year, with a return of 76.63%, the stock has recently seen a decrease in investor participation, as evidenced by a 37.01% drop in delivery volume compared to the five-day average. While the company has demonstrated healthy long-term growth with net sales and operating profit increasing significantly, the recent price movement indicates a short-term struggle.
In the broader market context, SML ISUZU's short-term performance contrasts sharply with the benchmark Sensex, which has declined by 1.59% over the past week. Despite this, SML ISUZU has shown remarkable growth over longer periods, outperforming the Sensex with a year-to-date return of 158.05% compared to the Sensex's 3.52%. The recent increase in institutional investor participation, with a 0.75% rise in their stake, suggests confidence in the company's fundamentals, which may help stabilize the stock in the future. However, the current downward trend highlights the volatility and challenges the stock is facing in the short term.
