Why is A B Infrabuild falling/rising?

As of 25-Jun, A B Infrabuild Ltd's stock price is rising, currently at Rs. 156.35, reflecting an increase of Rs. 3.55 or 2.32%. The stock has reached a new 52-week and all-time high of Rs. 157 today, outperforming its sector by 1.32%. Over the past week, the stock has gained 2.86%, and it has shown a remarkable year-to-date increase of 59.54%. The company's strong financial performance is underscored by a low Debt to EBITDA ratio of 0.66 times and impressive growth in net sales and operating profit, which have increased at annual rates of 26.80% and 31.59%, respectively. However, there is a noted decline in investor participation, with delivery volume falling by 47.13% against the 5-day average.
In the broader market context, A B Infrabuild's short-term performance has outpaced the Sensex, which has only risen by 1.61% over the past week. This indicates that the stock is not only performing well on its own but is also gaining traction relative to the overall market. Despite the positive indicators, such as consistent quarterly growth and strong operating profit, the stock's valuation is considered expensive with a ROCE of 19.6 and an enterprise value to capital employed ratio of 7.3. This suggests that while the stock is currently rising, there are underlying risks related to its valuation that investors should consider.
