Why is A B B falling/rising?

As of 22-Sep, ABB India Ltd's stock price is currently at 5,360.00, reflecting a decline of 77.65 points, or 1.43%. The stock has recently underperformed its sector by 0.81% and has experienced a trend reversal, falling after nine consecutive days of gains. Over the past week, the stock has increased by 0.39%, but its year-to-date performance shows a significant decline of 22.54%. Despite a healthy long-term growth rate in operating profit and a low debt-to-equity ratio, the company reported a drop in profit after tax for the quarter, which has contributed to the stock's negative movement. The stock's valuation appears high relative to its return on equity, and it has underperformed the market significantly over the past year, with a return of -30.47%.
In the broader market context, the Sensex has shown a slight increase of 0.46% over the past week, while ABB India Ltd's performance has lagged behind with a 0.39% gain. The stock's year-to-date decline of 22.54% starkly contrasts with the Sensex's positive return of 5.15% during the same period. This underperformance indicates that while the overall market has been recovering, ABB India Ltd has struggled to keep pace, exacerbated by its recent quarterly results and high valuation metrics compared to its peers.
