Is Zeta Global Holdings Corp. overvalued or undervalued?

As of 10 August 2021, Zeta Global Holdings Corp. has moved from a grade of "does not qualify" to "risky." The company is currently overvalued, given its significant negative financial metrics. Key ratios include a Price to Book Value of 4.84, an EV to EBITDA of 133.74, and a ROCE of -7.17%.
In comparison to its peers, Zeta Global's valuation is starkly unfavorable; for instance, Clearwater Analytics Holdings, Inc. has a P/E ratio of 12.55 and an EV to EBITDA of 127.79, while SolarWinds Corp. shows a P/E of 25.03 and an EV to EBITDA of 13.67. The company has shown strong stock performance recently, with a 1-week return of 33.41% compared to a slight decline in the S&P 500, but this does not mitigate the overall overvaluation indicated by its financial ratios.
