Why is A B B falling/rising?

As of 22-Aug, ABB India Ltd's stock price is currently at 5,060.85, reflecting a decline of 79.7 points or 1.55%. The stock has recently underperformed its sector by 0.73% and has experienced a trend reversal, falling after four consecutive days of gains. In terms of returns, the stock has seen a 12.06% decline over the past month and a significant 35.52% drop over the past year, while the broader market benchmark, the Sensex, has only decreased by 1.07% and 0.31% respectively during the same periods. Despite the company's strong long-term fundamentals, including a low debt-to-equity ratio and high return on capital employed, the stock's performance has been negatively impacted by rising raw material costs and a very expensive valuation relative to its peers.
In the broader market context, ABB India Ltd's short-term performance has lagged behind the Sensex, which has gained 0.88% over the past week while ABB's stock has only increased by 0.64%. This underperformance is notable given that the stock has generated a return of -35.52% over the past year, significantly worse than the market's decline of -2.49%. The company's high price-to-book value and low interest coverage ratio further contribute to investor concerns, leading to a lack of confidence in the stock's ability to recover in the near term. Overall, the combination of negative short-term trends, high valuation concerns, and rising costs has contributed to the stock's current downward movement.
