Why is Tech Mahindra falling/rising?

As of 28-Aug, Tech Mahindra Ltd. is experiencing a decline in its stock price, currently at 1,495.00, reflecting a decrease of 7.2 points or 0.48%. The stock has been underperforming recently, having fallen consecutively for the last two days with a total decline of 1.89%. In terms of performance against benchmarks, the stock has shown a negative return of 1.72% over the past week, while it has outperformed the sector by 1.26% today. Despite a high management efficiency indicated by a return on equity (ROE) of 16.04% and positive results over the last five quarters, the stock's long-term growth prospects appear poor, with an operating profit growth rate of only 6.59% over the last five years.
In the broader market context, Tech Mahindra's performance has been relatively weak compared to the Sensex, which has declined by 2.34% over the past week. The company's year-to-date return stands at -12.34%, contrasting with the Sensex's positive return of 2.48%. This consistent underperformance against the benchmark over the past three years, coupled with a high price-to-book value ratio, suggests that the stock is trading at a premium compared to its peers. While rising investor participation and liquidity may provide some support, the overall sentiment remains cautious due to the stock's historical underperformance and expensive valuation relative to its growth prospects.
