Why is Tech Mahindra falling/rising?

As of 18-Aug, Tech Mahindra Ltd. is experiencing a decline in its stock price, currently at 1,471.15, reflecting a decrease of 15.15 points or 1.02%. The stock has underperformed its sector by 0.57% today and has been on a downward trend for the last three days, accumulating a total decline of 2.56%. Additionally, the stock is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages. Over the past week, Tech Mahindra has seen a return of -0.77%, and its performance over the last month is down by 5.00%. While the company has reported positive results for the last five consecutive quarters, including a significant growth in PAT, it faces challenges such as poor long-term growth and a high valuation compared to its peers, which may be contributing to the recent price decline.
In the broader market context, Tech Mahindra's recent performance contrasts with the Sensex, which has increased by 0.83% over the past week. The stock's underperformance is evident as it has generated negative returns over various periods, including a -7.19% return over the last year, while the Sensex has gained 1.04%. Despite high institutional holdings and management efficiency, the stock's valuation concerns and below-par performance in both the short and long term are likely influencing investor sentiment negatively, leading to its current price drop.
