Is Tupperware Brands Corp. overvalued or undervalued?

As of 31 January 2018, Tupperware Brands Corp. has moved from a valuation grade of very attractive to risky, indicating a significant deterioration in its financial outlook. The company is currently assessed as overvalued, particularly given its negative price-to-earnings (P/E) ratio of -0.014 and a price-to-book value of -0.00. Additionally, the enterprise value to EBITDA ratio stands at 12.49, which is relatively high compared to its peers.
In comparison to its industry, Tupperware's valuation metrics are concerning. For instance, TriMas Corp. is classified as very expensive with a P/E of 40.97, while Daktronics, Inc. holds a fair valuation with a P/E of 23.31. The stark contrast in performance is further highlighted by Tupperware's return metrics, where it has experienced a staggering 98.72% decline over the past year, compared to a 10.26% gain in the S&P 500. This underperformance reinforces the view that Tupperware Brands Corp. is currently overvalued.
