Why is Kennametal India falling/rising?

As of 21-Aug, Kennametal India Ltd's stock price is currently at 2,143.95, reflecting a decline of 36.15 points or 1.66%. The stock has been underperforming, having fallen consecutively for the last two days with a total return of -2.55% during this period. Additionally, the stock has underperformed its sector by 2.21%. Over the past week, it has decreased by 1.57%, and its year-to-date performance shows a significant decline of 27.73%. Despite a healthy operating profit growth rate of 36.43% annually, the stock's valuation appears expensive with a Price to Book Value of 6, and it has generated a return of -28.02% over the past year, indicating a troubling trend in its performance.
In the broader market context, the Sensex has increased by 1.74% over the past week, contrasting sharply with Kennametal India's decline. The stock's performance has been notably below par compared to the benchmark indices, as it has underperformed the BSE500 over the last three years, one year, and three months. This underperformance, coupled with a low Debt to Equity ratio and rising investor participation, suggests that while there may be some long-term growth potential, the immediate outlook remains challenging due to flat results and high valuation metrics.
