Is Diana Shipping, Inc. overvalued or undervalued?

As of 28 November 2025, the valuation grade for Diana Shipping, Inc. moved from fair to expensive. The company appears to be overvalued based on its current metrics. Key ratios include a P/E ratio of 16, a Price to Book Value of 0.39, and an EV to EBITDA of 6.50. In comparison, Genco Shipping & Trading Ltd. has a P/E of 46.00, indicating a much higher valuation, while Tsakos Energy Navigation Ltd. shows a more attractive P/E of 4.29.
Despite recent strong performance, with a 1-week return of 17.26% compared to the S&P 500's 3.73%, the longer-term outlook is concerning, as the stock has underperformed the S&P 500 over the 3-year and 5-year periods. This suggests that while there may be short-term gains, the overall valuation does not support a sustainable investment case at current levels.
