Is Cummins India overvalued or undervalued?

As of 28 January 2021, Cummins India has moved from an expensive to a very expensive valuation grade. The company is currently overvalued based on its financial metrics. Key ratios include a PE Ratio of 46.90, an EV to EBITDA of 43.45, and a Price to Book Value of 12.41, which are significantly higher than the industry average.
In comparison to its peers, Kirloskar Oil is rated as attractive with a PE Ratio of 27.32 and an EV to EBITDA of 14.27, while Greaves Cotton is categorized as very expensive with a PE Ratio of 77.08. This indicates that Cummins India is trading at a premium relative to its competitors. Additionally, despite a strong return of 232.50% over the past three years compared to the Sensex's 49.15%, the current valuation suggests that the stock may not provide sufficient upside potential given its elevated price levels.
