Why is Coforge falling/rising?

As of 23-Sep, Coforge Ltd's stock is currently priced at 1,668.10, reflecting a decline of 48.45 points or 2.82%. The stock has been underperforming, having lost 8.65% over the last three days and is trading below all key moving averages. Additionally, it has underperformed its sector by 2.23% today. Despite a strong long-term fundamental outlook, with an average return on equity of 20.41% and consistent positive results over the last four quarters, the stock's recent performance has been hampered by a high valuation relative to its peers, indicated by a price-to-book ratio of 8.7 and a PEG ratio of 2.5.
In the broader market context, Coforge's short-term performance has been notably weaker than the benchmark, as it has declined by 6.33% over the past week while the Sensex has only fallen by 0.34%. This stark contrast highlights the stock's struggles despite its historical performance, which has outpaced the market over longer periods, such as a 21.27% return over the past year compared to the Sensex's decline of 3.33%. The combination of high institutional holdings and strong long-term growth potential suggests that while the stock may face short-term challenges, its fundamentals remain robust.
