Is Jack in the Box, Inc. overvalued or undervalued?

As of 17 February 2016, the valuation grade for Jack in the Box, Inc. has moved from expensive to risky, indicating a shift in perception regarding its financial health and market position. The company is currently deemed undervalued based on its low P/E ratio of 9, a PEG ratio of 0.25, and a remarkable dividend yield of 162.70%. However, the negative price-to-book value of -1.67 raises concerns about its asset valuation.
In comparison to its peers, Jack in the Box, Inc. has a P/E ratio of 8.18, significantly lower than Wingstop, Inc. at 55.34 and The Wendy's Co. at 24.56, which suggests that it is trading at a discount relative to these competitors. Furthermore, the EV to EBITDA ratio of 10.53 for Jack in the Box is more favorable compared to the industry average, reinforcing the notion that the stock may be undervalued. Despite the company's poor stock performance relative to the S&P 500 over various time frames, the current valuation metrics indicate potential upside for investors willing to take on the associated risks.
