GDS Holdings has printed its Q1 results and the stock is sliding — down 5.5% on the week to $40.41 — yet the borrow market remains near-completely exhausted, and short interest is quietly rebuilding.
The lending picture is the most striking feature of the current setup. Availability has tightened back to just 2.2% — barely two shares sit available for every hundred already on loan. That is close to the tightest level of the past year, the 52-week floor having touched 0.45% in mid-April. What makes this week different from the pre-earnings note is the direction of short interest itself: it has climbed 5.5% over the past five sessions to 5.0% of the free float, reversing a sharp post-May-8 unwind that had briefly pulled the position below 10 million shares. Cost to borrow has edged up to 1.40%, a modest 6% rise on the week and well below the 2% levels seen in late April, so there is no sign of a squeeze premium — but the combination of rising SI and near-zero availability means any new short demand has almost nowhere to go in the lending market.
Options traders are leaning the other way. The put/call ratio has drifted up to 0.39 from a mid-week low near 0.33 — still below the 20-day average of 0.42 and not far above the 52-week floor of 0.33. Call volume continues to dominate, suggesting the options market is not particularly alarmed by the post-earnings drop. The ORTEX short score of 67.2 tells a more bearish story than options do: it has been running in the mid-60s all week, after a notable step-down from the low-70s seen on May 7-8 when the old, larger short position was in place. The utilization rank sits in the bottom 1% of the universe — effectively, the borrow pool has no slack.
The Street remains broadly constructive, though recent analyst activity is dated enough to treat with caution. The most recent changes on record are from late 2025: TD Cowen trimmed its target modestly to $37 while holding a Buy in November, and BofA lifted its target to $50.60 also around that period. At a current price of $40.41, the stock now trades below BofA's target and well within the bull case's 16.5x 2026 EBITDA framing — though that framing was set months ago. The EV/EBITDA multiple has compressed to 14.7x, down roughly 0.4 turns over 30 days, drifting toward the low end of prior guidance ranges. EPS momentum factor scores are notably strong — 86th percentile on a 30-day basis and 99th on a 90-day basis — pointing to a pattern of positive estimate revisions even as the stock retreats. The bull case centres on the C-REIT conversion potential and international EBITDA exceeding $1 billion by 2028; the bear case flags Chinese tech demand weakness and REIT market structural headwinds that could erode the sum-of-the-parts premium.
Among correlated peers, the week has been mixed. VNET surged 11.9% over the past five days, sharply outperforming GDS's decline — suggesting the China data-centre theme is alive in at least some names. Applied Digital dropped 16.6% over the same window, highlighting the volatility across the broader AI infrastructure complex. GDS's underperformance relative to VNET this week is notable given the two carry the highest correlation in the peer group at 66%.
The next data point worth tracking is whether short interest continues to rebuild above the 10 million share level now that earnings are out of the way — and whether the borrow market loosens enough to accommodate new positions or stays pinned near zero availability.
