Why is Tata Technolog. falling/rising?

As of 06-Nov, Tata Technologies Ltd is experiencing a decline in its stock price, currently at 677.55, which reflects a decrease of 9.0 points or 1.31%. The stock has underperformed its sector by 1.4% today and has been on a downward trend for the last two days, accumulating a total return loss of 2.69%. Over the past week, the stock has decreased by 3.19%, and its year-to-date performance shows a significant drop of 24.13%. Despite a high management efficiency indicated by a return on equity (ROE) of 20.00% and a low debt-to-equity ratio, the company has reported flat results in its latest quarter, with profits falling by 0%. This has contributed to the stock's expensive valuation, trading at a price-to-book value of 7.7, which is seen as a negative factor in light of its recent performance.
In the broader market context, Tata Technologies' short-term performance is notably worse than the benchmark, with the Sensex showing a decline of only 1.30% over the same week. The stock's long-term performance is also concerning, as it has generated a return of -34.42% over the past year, underperforming the BSE500 index across various time frames. This underperformance, coupled with the company's recent flat results and high valuation, suggests a lack of investor confidence, which is reflected in the stock's current price movement.
