Delta Air Lines heads into the final stretch before its June earnings with short sellers and options traders moving in the same direction — a notable alignment after a relatively quiet positioning backdrop for most of 2026.
The clearest signal this week is the accelerating rebuild in short interest. SI climbed to 4.2% of the free float as of May 14, up 9% on the week and 25% over the past month. That brings the position to its highest level in the tracked 30-day window, with the sharpest single-session jump occurring between May 11 and May 13 — an addition of over 3 million shares in two days. On its own, 4.2% is not extreme. But the pace of accumulation is notable and suggests fresh conviction rather than residual positioning from the April tariff-shock period, when SI was running closer to 21-22 million shares.
Options traders are sending a consistent message. The put/call ratio hit 1.20 on May 15, more than two standard deviations above its 20-day average of 1.11 — putting it at one of the most defensive readings of the past year. The 52-week range runs from 0.63 to 1.23, so the current level is close to maximum defensiveness on this measure. Borrow conditions remain relaxed — cost to borrow nudged up to 0.49%, roughly a third above last week's level but well inside any squeeze territory. Availability is ample, meaning new short positions face no friction from the lending market. The setup is bears building positions they can enter freely, not a structurally constrained short base.
The Street remains firmly constructive. Both Bernstein (this week, raising to $88 from $81) and UBS (last week, raising to $95 from $86) maintained positive ratings while lifting targets after the April earnings beat. That beat was real — DAL posted a +3.4% next-day move on April 8 and followed through with a further +9.7% over the subsequent five days. Broader analyst direction has been upward since Q1 results, with the consensus mean target at $80.09 against a current price of $70.23 — implying roughly 14% upside to Street consensus. The PE stands at 11.1x and EV/EBITDA at 7.1x, both modest for a carrier reporting estimated revenue north of $70bn. The EV/EBIT factor ranks in the 71st percentile, pointing to reasonable value on an earnings basis. EPS momentum over 30 days ranks in the 68th percentile, though the 90-day read is weaker at the 22nd — suggesting estimate revisions have been front-loaded in recent weeks.
Insider activity adds a less bullish nuance. COO John Laughter sold $5.8 million in two tranches in April, and a divisional president offloaded $1.5 million in early May. CEO Ed Bastian sold $7 million in late February. No purchases are visible in the trailing 90-day window; net insider activity amounts to over $53 million in sales. These are largely scheduled or compensation-related in form, but the volume and spread across multiple senior executives is a pattern worth noting heading into the summer travel season.
Peers confirm the sector is under broad pressure. UAL fell 6.8% on the week, AAL dropped 7.8%, and ALGT lost nearly 10% — making DAL's 4.2% weekly decline the most contained in the group. Relative resilience is one way to read that; the next question is whether the sector-wide softness pulls DAL lower into June, or whether the premium valuation narrative holds with the next earnings print on June 18 approaching.
What to watch next: the rate at which short interest continues to build over the coming two weeks and whether borrow availability tightens materially — two of the three conditions for a more charged setup ahead of the June 18 Q2 report are already in place.
