Why is HEC Infra Proj. falling/rising?

As of 30-Jun, HEC Infra Projects Ltd is currently priced at 172.28, reflecting a decrease of 3.52, or 2.0%. Today's performance indicates that the stock has underperformed its sector by 4.39%. Despite this decline, the stock has shown strong returns over various periods, including a 25.31% increase over the past month and an impressive 639.40% rise over the last three years. The company has reported healthy long-term growth, with net sales increasing at an annual rate of 30.18% and operating profit at 67.19%. However, concerns regarding management efficiency are evident, as indicated by a low return on capital employed (ROCE) of 5.85% and a high debt to EBITDA ratio of 7.87 times, which may be contributing to the stock's current downward movement.
In the broader market context, the stock's short-term performance over the past week shows a gain of 2.84%, which is better than the benchmark Sensex's increase of 2.18%. However, the recent decline in price suggests that investors may be reacting to the company's financial metrics, particularly its low profitability per unit of capital and high debt levels, despite the positive indicators of rising promoter confidence and consistent returns over the past year. The stock's current valuation appears expensive relative to its profitability, which could be causing some hesitation among investors, leading to the recent price drop.
