Interpretation of the Ratios

Western Digital Corporation

Western Digital shows slightly favorable ratios with strong net margin at 19.55% and impressive returns on equity (35.04%) and invested capital (21.53%). Concerns include a high price-to-book ratio (4.14) and a weak dividend yield of 0.2%. The company pays dividends, but the low yield suggests cautious monitoring of payout sustainability and buyback activities.

Seagate Technology Holdings plc

Seagate’s ratios are generally favorable, with solid returns on invested capital (33.76%) and asset turnover (1.13). However, a deeply negative return on equity (-324.28%) and a high debt-to-assets ratio (66.97%) raise concerns. The firm pays a higher dividend yield of 2.0%, supported by share buybacks, though care is needed given financial leverage.

Which one has the best ratios?

Seagate displays a higher proportion of favorable ratios (57.14%) compared to Western Digital’s 35.71%, reflecting stronger operational efficiency and dividend yield. Nonetheless, both face notable challenges: Western Digital’s valuation metrics and Seagate’s leverage and negative equity returns require investor vigilance in risk management.
