DIGI Spain Borrow Pool Swings Wildly as Shorts Rebuild

DIGIS enters the final week of September with an unusual lending market story — availability has collapsed from historically loose levels to a still-very-comfortable position in just ten days, while the short score quietly ticks higher and the stock drifts lower on the month.

The most striking feature this week is how fast the borrow picture changed. Availability was running above 6,000% as recently as mid-September — an extraordinarily loose pool with almost no shares on loan. Then something shifted. By September 4, availability had tightened all the way to 342%, the tightest reading in the past year. It has since loosened back to around 1,412%, but that still marks a dramatic compression from where it was. The borrow cost has edged down too, falling roughly 1% on the week to just under 6%, though it remains elevated relative to the summer — cost to borrow only broke above 6% in late July and has held around that level since. The overall lending picture remains loose by most standards, but the speed of the September swing is worth flagging.

The short score reinforces that something is stirring. The ORTEX short score for DIGIS climbed from 29.6 in mid-September to 33.5 by September 24 — a meaningful step higher, even if the absolute level stays firmly in the low-risk range. The score had briefly touched 39 on September 11, right around the peak tightening in availability, before easing as the lending pool loosened. The current trajectory is upward again. Short interest as a percentage of free float remains very low at roughly 0.3%, so there is no genuine short squeeze story here, and no meaningful crowding. The rebuilding is modest — what it suggests is that a small group of participants added to positions when the stock sold off.

That monthly decline is the real backdrop. DIGIS has dropped about 8% over the past month to €6.47, recovering just 0.3% on the week and adding 1.6% on Friday. The underperformance sits against a resilient European telecom sector — peers including Deutsche Telekom and Telefónica posted weekly gains of around 2% and 1.6% respectively over the same window. The ORTEX stock score has actually improved, rising from 57 to 62 over the past month, with momentum and quality both contributing positively. The EV/EBITDA multiple has drifted lower — down roughly 0.26 turns over 30 days to 8.2x — which modestly reduces valuation pressure. The PE remains elevated at around 121x, reflecting thin trailing earnings rather than a growth premium re-rating.

Ownership is highly concentrated. Digi Communications N.V. holds 81.6% of shares, with Indumenta Pueri holding another 6%. That leaves very little true free float, which amplifies the borrow dynamics seen this month — small changes in lending demand translate into large swings in availability percentage. Wellington Management holds a negligible 0.04%. The next earnings event is scheduled for November 13. The most recent print, in August, saw the stock dip around 1% on the day before recovering nearly 6% over the following week — a pattern that suggests the market tends to overreact negatively on day one and recalibrate once results are digested.

With the stock down sharply on the month and the short score nudging higher, the November 13 earnings print becomes the clearest near-term focus — particularly whether subscriber growth and fiber deployment updates can close the gap with peers that have held up better through September.
