Sandisk Corporation vs Seagate Technology Holdings plc, two Computer Hardware stocks. A side-by-side on valuation, growth, margins, returns, and what each price is betting.
Both prices bet the storage shortage is a new order rather than a hot summer, and they bet it through different media: Sandisk at 72.5 times earnings on flash, Seagate at 85.1 times on spinning disk. The margins say flash is currently the better business by a mile, a 69.1% operating margin against 32.1%, both at cyclical highs. The balance sheets say who prepared: Sandisk debt-free with a 4.8 current ratio, Seagate at 3.5 turns of debt to equity, its 217% return on equity an artifact of exactly that gearing (26.7% on assets is the real figure, in a dead heat with Sandisk's 26.4%). Premium multiples on peak cyclical earnings, twice over; the pair is the market's clearest statement that it believes AI data demand repealed the storage cycle.
