Why is ITD Cem falling/rising?

As of 14-Jul, ITD Cementation India Ltd is currently priced at 861.65, reflecting a decline of 11.35 points or 1.3%. The stock has been underperforming recently, having fallen for the last three consecutive days, resulting in a total drop of 4.34% during this period. Additionally, the stock has underperformed its sector by 0.56% today. Despite a strong performance over the longer term, with a year-to-date increase of 59.83% and a remarkable 84.19% rise over the past year, the recent trend indicates a slowdown in investor participation, as evidenced by a significant drop in delivery volume by 50.03% compared to the five-day average. The stock remains above its longer-term moving averages but is currently below its five-day moving average.
In the broader market context, ITD Cementation's short-term performance has been slightly better than the benchmark Sensex, which has declined by 1.42% over the past week, while ITD Cementation has only fallen by 1.19%. However, the stock's valuation appears to be a concern, as it is considered very expensive with a high ROCE of 32.4 and a PEG ratio of 1.1, despite its strong management efficiency and consistent returns over the last three years. The high institutional holdings at 20.1% suggest that knowledgeable investors are backing the company, but the recent price decline may reflect market corrections or profit-taking after substantial gains.
