Is KULR Technology Group, Inc. overvalued or undervalued?

As of 16 August 2021, KULR Technology Group, Inc. has moved from a valuation grade of "does not qualify" to "risky." The company is considered overvalued given its current financial metrics and peer comparisons. Key ratios include a Price to Book Value of 3.93, an EV to EBIT of -16.40, and a ROCE of -30.50%.
In comparison to its peers, KULR's P/E ratio is not applicable due to its loss-making status, while Graham Corp. shows a P/E of 45.56, indicating it is expensive, and Natural Gas Services Group, Inc. has a fair P/E of 18.93. The significant disparity in valuation metrics suggests that KULR is not justified at its current price of 6.69, especially considering its recent stock performance, which has outperformed the S&P 500 over various time frames, including a staggering 1-year return of 1761.95%.
