As of 28 June 2021, Hindustan Copper's valuation grade has moved from risky to very expensive. The company is currently overvalued, with a PE ratio of 53.21, a Price to Book Value of 9.30, and an EV to EBITDA of 33.69. In comparison to its peers, Hindustan Zinc has a PE ratio of 20.37 and an EV to EBITDA of 12.30, while Vedanta stands at a PE ratio of 12.87 and an EV to EBITDA of 5.42, highlighting the significant premium at which Hindustan Copper is trading.

While the company has outperformed the Sensex in the short term, with a 1-month return of 26.10% compared to the Sensex's 3.86%, the long-term performance shows a decline of 23.72% over the past year, further indicating potential overvaluation concerns.
