Western Digital heads into its August 5 earnings release with a stock that has ripped 18% higher in a week yet still carries 7% of its float in short positions — a tension that makes tonight's print more consequential than the price action alone suggests.
The short interest story has barely shifted since the July 30 rally. Bears hold roughly 23.7 million shares, equivalent to 6.9% of the free float — virtually unchanged from the 6.88% flagged two days ago and still near the elevated level that has persisted for weeks. That 18% single-session jump on July 30 results forced no meaningful short covering. Borrowing costs run at just 0.45%, and borrow availability is extraordinarily loose at around 2,460% — nearly 25 shares available to lend for every one currently borrowed. There is no squeeze pressure here. The shorts are comfortable holding, and the lending market gives them no reason to rush for the exit.
Options positioning reinforces the cautious undertone. The put/call ratio is running at 2.58, fractionally below its elevated 20-day average of 2.60. That average itself is the story: WDC options have been structurally dominated by put demand for months, with the ratio sitting far above 1.0 as a matter of course. Tonight's reading looks like stability rather than conviction. Last week's brief pre-earnings call rotation — when the PCR crashed to 1.49 ahead of the July 30 print — has fully reversed. Options traders are back to hedging rather than speculating, and the put/call ratio's 52-week range of 0.54 to 4.73 puts the current reading squarely in the middle of its defensive band.
The Street remains bullish despite persistent short positioning. A near-uniform wave of target-price increases has run through coverage since June: Citigroup lifted to $800, Cantor Fitzgerald to $900, Wells Fargo to $730, B of A Securities to $732, with Morgan Stanley and JPMorgan each moving to $650. The mean target of $655 implies roughly 19% upside from Tuesday's close of $548.56 — meaningful, but the gap has narrowed sharply as the stock has recovered. Bulls point to WDC's dominant position in the HDD duopoly, data center pricing strength, and consistent cash generation. Bears focus on HAMR technology execution risk, potential HDD oversupply, and the company's concentrated exposure to hyperscaler capex cycles — a demand source that can turn quickly. The EPS momentum picture supports the bulls: the 90-day forward EPS momentum factor scores in the 97th percentile, a reading that has climbed sharply since January.
Peer performance this week lends context. Highly correlated storage name STX gained 13% on the week, running broadly in line with WDC's move. SNDK went further, up 30% — though that name carries a different risk profile. The storage complex has broadly been bid, suggesting some macro or sector tailwind rather than a WDC-specific story alone.
One institutional data point is worth noting. Capital Research and Management Company reported a last-change figure of 14.2 million shares added, a materially large move, and now holds 4.4% of shares outstanding. That kind of incremental conviction from a large active manager contrasts sharply with the independent chairman's decision to sell roughly $914,000 worth of shares in small tranches on July 28 — though the significance scores on those insider sales are low, and they occurred before the stock's subsequent 18% move.
Tonight's print will determine whether the bears who refused to cover after July 30 were right to stay patient or whether the setup forces another unwind.
