Why is IRB Infra.Devl. falling/rising?

As of 12-Aug, IRB Infrastructure Developers Ltd is currently priced at 44.71, reflecting an increase of 0.46 or 1.04%. The stock has shown positive momentum recently, gaining for the last two days with a total return of 2.69%. However, despite this short-term performance, the stock has underperformed over the past week and month, with declines of 0.64% and 6.11% respectively. Key financial metrics indicate a mixed picture; while the company reported a significant growth in profit after tax and a high debtors turnover ratio, it also faces challenges such as a low return on capital employed and a high debt to EBITDA ratio, which contribute to its weak long-term fundamental strength. Additionally, a significant portion of promoter shares being pledged may exert downward pressure on the stock.
In the broader market context, the stock has underperformed compared to the benchmark Sensex, which has shown a decline of only 0.59% over the past week and 2.75% over the past month. This stark contrast highlights the stock's struggles, particularly as it has generated a return of -28.31% over the past year, significantly worse than the market's negative return of -2.11%. The liquidity of the stock remains adequate, but a notable decrease in investor participation, with delivery volume falling by 31.16% against the five-day average, suggests waning interest, which could further impact its price movement in the near term.
