SMCI shorts keep unwinding as stock reclaims $39

Super Micro Computer has gained nearly 25% in a month, the short base keeps shrinking, and the Street has lifted targets — yet the consensus still refuses to turn bullish.

The most striking development in positioning is the continued, steady unwind of the short position. Short interest has fallen to 80.2 million shares, representing 13.4% of the free float — down another 3.4% on the week and roughly 14% lower than the mid-August peak near 93 million shares. That is a meaningful multi-week cover, not a one-day spike. The direction of travel is clear: shorts that built aggressively into the summer are quietly stepping back as the stock rallies. Borrow conditions offer no obstacle to that exit. Cost to borrow has collapsed nearly 37% in a week to just 0.32%, and availability has loosened materially to 233% — more than double the shares available relative to those already borrowed — far from the tighter conditions seen in mid-August when availability briefly compressed toward 104%. The ORTEX short score, which peaked at 63.4 on August 24, has drifted down to 59.3 by September 4, consistent with a structural reduction in short conviction rather than a temporary blip.

Options positioning is no longer the signal it was. Last week's note flagged that the panic-hedge spike to 0.87 on the put/call ratio had unwound. The PCR now runs at 0.71, just barely above its 20-day mean of 0.70, with a z-score of 0.64 — effectively neutral. The 52-week range runs from 0.59 to 0.90, placing the current reading squarely in the middle. Options traders have stopped rushing for insurance. There is no meaningful directional lean embedded in the options market right now, which itself is a contrast to the defensive posture that dominated through late August.

The Street is more sanguine than it was, but not convinced. Following the August earnings beat — the stock jumped nearly 20% the day after the print — most covering analysts raised their targets on August 12. The upgrades clustered at Needham (Buy, $46) and Rosenblatt (Buy, $51), while Citi, Barclays, and Wedbush nudged targets higher but kept Neutral ratings. Goldman Sachs maintained a Sell, lifting its target only to $34. The mean target now sits at $42.38, a modest 7% above the current price of $39.59. That narrow gap means the Street is largely priced into today's level — bulls see a path to the low $50s, bears at Goldman see 14% downside from here. The factor picture reinforces the split: EPS momentum scores are exceptional, ranking in the 99th percentile on a 30-day basis and the 96th on 90 days, and the company's earnings surprise track record is in the 89th percentile. Against that, the short score rank sits at just the 7th percentile — an unusually bearish positioning read relative to peers — and forward EPS growth ranks in only the 22nd percentile, suggesting consensus still prices in limited growth beyond the near-term beat cycle.

The bull case rests on the AI server backlog and SMCI's embedded position in GPU-based infrastructure, where revenue now skews heavily toward that segment. The bear case is blunter: margin compression from the GPU mix shift, customer concentration, and a fragmented competitive environment in AI infrastructure where pricing power is eroding. One institutional data point worth noting: Jane Street trimmed its disclosed stake from 8.5% to 7.4% as of August 13 — a passive 13G/A filing, not an activist move, but a notable reduction as the stock rallied. No 13D activist appears on the register. All 13D/G stakes are as-last-disclosed and holders dropping below 5% may not file again.

The next hard date is the November 3 earnings call. Between now and then, the key question is whether the short cover continues at the current pace, or whether fresh shorts re-enter as the stock approaches the $42–$46 zone where multiple analyst targets cluster and upside becomes harder to argue.
