Western Digital has had a week defined by two sharp reversals: short sellers covered aggressively, and the options market — which had just turned its most bullish in over a year — pulled back sharply toward its prior defensive posture.
The short interest move is the headline number. Roughly 4.4 million shares were covered in a single session on August 25, dropping short interest from around 24.5 million shares to just over 20.2 million. That one-day unwind of nearly 18% brought SI as a percentage of free float down to 5.9% — still meaningful, but the steepest single-session reduction the stock has seen in the past six weeks. The prior note flagged short interest at 7.2% of float and climbing; that trend has now reversed explicitly. The lending market remains wide open throughout: availability runs at roughly 2,587% of existing short interest, meaning there is an abundance of shares to borrow for anyone wanting to rebuild a position. Cost to borrow stays near 0.44%, barely changed on the week, confirming there is no mechanical squeeze pressure driving the cover — this looks more like a deliberate unwind than a forced exit.
Options positioning has moved in the opposite direction. The previous article noted the put/call ratio had collapsed to historic lows near 1.30, a near four-standard-deviation swing toward calls. That reading has now partially reversed — the PCR climbed back to 1.40 on August 25, still well below the 20-day mean of 2.37, but the z-score of -3.67 shows the market remains far less defensive than its recent average. Put differently: options traders are less bearish than they have been for most of the past year, but the extreme call-buying enthusiasm that followed the earnings selloff has modestly cooled. The 52-week PCR range runs from 0.54 to 4.73, and the current reading sits closer to the bullish end — just not at the peak reached last week.
The Street remains mixed but skews toward optimism on valuation even as targets have come in. Following the August 5 earnings print — which produced a 17.7% single-day drop and a similar five-day loss — several analysts trimmed targets while holding constructive ratings. Citigroup cut to $740 from $800, UBS lowered to $525 from $560, and Rosenblatt came down to $800 from $900, all maintaining their existing stances. TD Cowen moved against the grain, lifting its target to $540 from $500. The consensus sits at hold with five analysts there, against zero underperforms — a configuration that says the Street is cautious on near-term execution rather than structurally bearish. At $450.75, the stock closed up 3.5% on the day but is still down 9.2% on the week and 13.3% over the past month. Bulls point to data-center storage demand and WDC's HDD market position; bears flag slower-than-expected nearline exabyte growth and the risk that the current pricing cycle requires sustained high prices to fund ongoing product transitions. The EPS momentum factor scores tell a striking story: 91st percentile on 30-day and 98th percentile on 90-day EPS momentum, yet the forward year-over-year EPS growth rank sits at just the 7th percentile — a gap that captures the core tension between recent beat history and where consensus sees the next cycle heading.
Institutional ownership adds a data point worth noting. Capital Research and Management added over 6 million shares in the most recent reported period through July 31, the largest single-holder change in the top-15. That is a meaningful accumulation relative to their existing 21.3 million share position and runs directly counter to the insider activity on the same name: the CEO, COO, CLO, and CMO all sold shares on August 20–21 at prices around $459–$469, with the CLO adding further sales on August 24. The insider net over 90 days is technically positive at roughly 28,000 shares and $12.7 million in net value, but the recent cluster of C-suite selling into the post-earnings bounce is a different signal from the longer-term aggregate — worth tracking against the institutional accumulation rather than reading in isolation.
The next earnings event is scheduled for October 29. Between now and then, the key variables to watch are whether the PCR continues to drift back toward its 2.37 average — which would suggest the post-earnings call enthusiasm is fading — and whether short interest stabilises near the new lower 5.9% level or rebuilds as the stock attempts to recover the ground lost since August 5.
