Why is A B Infrabuild falling/rising?

As of 22-Jul, A B Infrabuild Ltd's stock price is rising, currently at Rs. 179.50, reflecting an increase of Rs. 6.65 or 3.85%. The stock has recently hit a new 52-week and all-time high, outperforming its sector by 3.99%. Over the past week, the stock has gained 4.36%, and in the last month, it has surged by 21.61%. The company has shown strong financial performance, with a significant growth in net sales and operating profit, contributing to positive investor sentiment. However, there has been a notable decline in investor participation, with delivery volume dropping by 92.26% against the 5-day average, which could indicate caution among investors despite the stock's upward movement.
In the broader market context, A B Infrabuild's recent performance stands in stark contrast to the benchmark Sensex, which has seen a decline of 0.47% over the past week. This divergence highlights the stock's strong momentum, particularly as it has achieved substantial year-to-date growth of 83.16% compared to the Sensex's modest 5.18%. The company's low debt-to-EBITDA ratio and consistent positive quarterly results further bolster its appeal, suggesting that the stock's rise is supported by solid fundamentals, despite the recent drop in trading volume.
