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

As of 11 May 2020, the valuation grade for Cooper-Standard Holdings, Inc. moved from expensive to risky, indicating a shift in perception regarding its valuation. Based on the available metrics, the company appears to be overvalued, particularly given its negative price-to-book value of -3.36 and a relatively high EV to EBITDA ratio of 6.33 compared to peers. Additionally, the company has a P/E ratio that is not applicable due to losses, which further complicates its valuation.
In comparison to its peers, American Axle & Manufacturing Holdings, Inc. has a more favorable EV to EBITDA ratio of 4.0153, while Holley, Inc. shows a P/E of 21.6456, both suggesting better valuations in the industry.
