Is Cooper-Standard Holdings, Inc. overvalued or undervalued?

As of 11 May 2020, the valuation grade for Cooper-Standard Holdings, Inc. has moved from fair to risky, indicating a significant change in its financial outlook. The company appears to be overvalued given its current financial metrics, including a Price to Book Value of -3.36 and an EV to Sales ratio of 0.50. The EV to EBITDA ratio stands at 6.33, which, while not excessively high, does not compensate for the negative P/E ratio due to the company's loss-making status.
In comparison to its peers, Cooper-Standard's valuation is concerning; for instance, PHINIA, Inc. has a P/E of 18.52, while American Axle & Manufacturing Holdings, Inc. shows a P/E of 9.62, both of which suggest a more favorable valuation. Additionally, Cooper-Standard's Return on Capital Employed (ROCE) is at 13.24%, but this is overshadowed by its negative book value for Return on Equity (ROE). Despite a strong performance in the past year with a return of 73.17% compared to the S&P 500's 10.26%, the current valuation metrics suggest that Cooper-Standard is overvalued in the market.
