Why is Tech Mahindra falling/rising?

As of 11-Sep, Tech Mahindra Ltd. is experiencing a decline in its stock price, currently at 1,520.75, reflecting a decrease of 5.1 points or 0.33%. The stock has shown a trend reversal, falling after two consecutive days of gains. Despite this recent downturn, it has performed positively over the past week and month, with returns of 1.32% and 2.64%, respectively. The stock is currently trading above its 5-day and 20-day moving averages but below its longer-term moving averages, indicating mixed momentum. Positive factors such as high management efficiency, a low debt-to-equity ratio, and consistent positive results over the last five quarters contribute to its appeal. However, the stock's long-term growth prospects are hindered by a relatively low operating profit growth rate and a high valuation compared to peers, leading to concerns about its sustainability.
In the broader market context, Tech Mahindra's short-term performance has outpaced the benchmark Sensex, which has returned 1.03% over the past week and 1.17% over the past month. However, the stock has underperformed the benchmark over the longer term, with a year-to-date return of -10.84% compared to the Sensex's 4.36%. This consistent underperformance against the benchmark, coupled with a high price-to-book ratio and a low PEG ratio, raises questions about the stock's valuation and future growth potential, contributing to the current selling pressure.
