Why is Igarashi Motors falling/rising?

As of 22-Jul, Igarashi Motors India Ltd is experiencing a decline in its stock price, currently at 587.55, down by 4.75 (-0.8%). The stock has been underperforming recently, with a consecutive fall over the last four days, resulting in a total drop of 3.95%. Despite outperforming its sector by 0.26% today, the stock's delivery volume has significantly decreased, falling by 65.86% against the 5-day average. Over the past week, the stock has declined by 1.58%, while it has shown a more favorable performance over the past month with a gain of 25.84%. However, the company's long-term growth appears weak, with net sales and operating profit growth rates of only 9.43% and 4.53%, respectively, over the last five years.
In the broader market context, Igarashi Motors' short-term performance has lagged behind the benchmark Sensex, which has only declined by 0.47% over the same week. While the stock has generated an 11.81% return over the past year, its recent quarterly performance has raised concerns, with a significant drop in profit after tax and net sales at their lowest. The company's ability to service debt remains strong, indicated by a low Debt to EBITDA ratio, but the overall market sentiment may be affected by its expensive valuation and poor long-term growth prospects. Thus, despite some positive indicators, the combination of declining investor participation and disappointing quarterly results contributes to the stock's current downward trend.
