Is Hudson Technologies, Inc. overvalued or undervalued?

The company appears to be fairly valued based on its current metrics, with a P/E ratio of 17, a Price to Book Value of 1.26, and an EV to EBITDA of 8.77. In comparison to peers, Hudson's P/E ratio is significantly higher than CrossAmerica Partners LP at 8.77, but lower than BlueLinx Holdings, Inc. at 25.45, indicating a mixed competitive positioning.
