Why is Alpine Housing falling/rising?

As of 16-Sep, Alpine Housing Development Corporation Ltd is experiencing a decline in its stock price, currently at Rs 132.95, reflecting a decrease of Rs 1.55 or 1.15%. The stock has underperformed its sector today, with a consecutive fall over the last two days resulting in a total decline of 2.24%. Although it opened with a gain of 3.31% and reached an intraday high of Rs 138.95, it also touched a low of Rs 130.5. Over the past week, the stock has decreased by 1.52%, and in the last month, it has fallen by 6.41%. Despite positive results in the last three quarters, with significant growth in both profit after tax and net sales, the stock's long-term fundamental strength is considered weak, reflected in its low return on capital employed and poor growth rates over the past five years.
In the broader market context, the stock's recent performance contrasts sharply with the benchmark Sensex, which has increased by 1.58% over the past week and 2.21% over the past month. This underperformance is further highlighted by the stock's declining investor participation, with a notable drop in delivery volume. While the company has shown strong returns year-to-date and over the past year, its valuation appears expensive relative to its peers, contributing to investor caution. The stock's PEG ratio of 0.8 indicates that, despite its recent gains, the market may be pricing in concerns about future growth potential, leading to its current downward trend.
