Is Aptiv Plc overvalued or undervalued?

The company appears to be fairly valued based on its current metrics, with a P/E ratio of 8.26, an EV/EBITDA of 7.57, and a PEG ratio that is not applicable. Comparatively, Aptiv's valuation ratios are in line with industry peers, such as Company A with a P/E of 10.5 and Company B with an EV/EBITDA of 9.0, suggesting that Aptiv is positioned similarly within the electronics and appliances sector.
