Why is Landmark Cars falling/rising?

As of 24-Sep, Landmark Cars Ltd is experiencing a decline in its stock price, currently at 612.00, which reflects a decrease of 7.9 or 1.27%. The stock's performance today is in line with the sector, but it has shown a significant drop in investor participation, with delivery volume falling by 87.06% against the 5-day average. Over the past week, the stock has decreased by 5.88%, while it has seen a modest increase of 6.49% over the past month. However, year-to-date, the stock is down by 2.39%. The company has high institutional holdings at 22.45%, indicating that these investors are likely to have a better understanding of the company's fundamentals, which may contribute to the stock's current valuation challenges.
In the broader market context, the Sensex has decreased by 1.18% over the past week, indicating that the stock's short-term decline is more pronounced than the benchmark. Despite a flat performance in the latest financial results, the company has shown weak long-term fundamental strength, including a -17.40% CAGR growth in operating profits over the last five years and a high debt-to-EBITDA ratio of 3.24 times. Additionally, the stock's return on equity is low at 7.11%, and its profits have fallen by 57.9% over the past year, which suggests that the stock is trading at an expensive valuation relative to its fundamentals.
