Why is A B B falling/rising?

As of 23-Sep, ABB India Ltd's stock price is currently at 5,300.00, reflecting a decrease of 61.35 points or 1.14%. The stock has underperformed its sector by 0.39% today and has experienced a consecutive decline over the last two days, resulting in a total drop of 2.53%. In terms of returns, the stock has fallen by 0.96% over the past week and has a year-to-date decline of 23.40%. Despite its strong long-term fundamentals, including a low debt-to-equity ratio and significant operating profit growth, the recent quarterly performance has been disappointing, with a 20.3% fall in profit after tax and the lowest operating profit to net sales ratio recorded. This combination of underwhelming short-term results and high valuation metrics may be contributing to the stock's recent downward movement.
Broader market context indicates that while the Sensex has seen a slight decline of 0.34% over the past week, ABB India Ltd's performance has been notably worse, suggesting a lack of investor confidence in the stock compared to the broader market. The stock's significant year-over-year decline of 33.22% starkly contrasts with the market's negative return of only 4.69%, highlighting its underperformance. Additionally, the falling investor participation, as evidenced by a 29.16% drop in delivery volume, further underscores the challenges the stock faces in regaining momentum amidst a generally stable market environment.
