Frontier Group Holdings enters July with a striking split: the stock is up 30% in a month, yet short sellers are adding positions and options traders are at their most defensive all year.
The options market is flashing the loudest warning signal. The put/call ratio has reached 1.02 — essentially matching its 52-week high — and sits nearly 1.6 standard deviations above its 20-day average of 0.73. The move is sharp and recent: the PCR was running below 0.60 as recently as mid-June. That is not routine hedging. Investors are paying up for downside protection at exactly the moment the stock looks its most stretched, with ULCC closing at $7.91 on June 30.
Short interest reinforces that caution. Bears have added meaningfully into the rally — short interest climbed 13.5% over the past week to reach 10.3% of free float, with roughly 23.5 million shares short. That is a high absolute level for an airline of this size. The cost to borrow has risen 34% on the week to 0.71%, though it remains low in absolute terms, so there is no mechanical squeeze pressure. Availability is ample at 223% — more than two shares available for every one currently borrowed — which means new shorts can still establish positions without difficulty. The borrow market is loose even as positions grow, a combination that tends to allow short interest to keep climbing without the friction of a squeeze.
The Street's reaction to the rally has been to raise targets while keeping ratings subdued. Citi lifted its target from $5 to $9 last Thursday, the most bullish move on the tape. Barclays and UBS both raised targets to $7 — right around current price — while maintaining Underweight and Neutral ratings respectively. The consensus mean target of $6.17 now sits roughly 22% below the close, a notable inversion where the stock has outrun analyst conviction. Factor scores tell a similar story: EPS surprise ranks in the 95th percentile, and the 90-day EPS momentum score is strong at 84, but the short score ranks in just the 8th percentile — meaning ULCC scores poorly relative to peers on short-side pressure, a sign the model sees the short positioning as a genuine headwind. Closest peer ALGT gained 13.6% on the week, slightly outpacing ULCC's 9.1%, while AAL and UAL each added around 12%.
The earnings calendar adds a hard deadline: Frontier's next print is scheduled for August 3. The last report on May 5 produced a 16.9% single-day jump, the biggest positive reaction in the recent history. Before that, moves were modest. The bear case centres on a pre-tax margin that deteriorated from +3.3% to -7.5% year-over-year, leverage running at roughly 5x projected EBITDAR, and open labour contracts. The bull case rests on fleet efficiency and co-brand loyalty revenue growing 40% year-over-year. At present, options positioning suggests the market is more focused on the risks than the upside.
What to watch heading into August 3: whether short interest continues to build as the stock holds above $7 — the level where two of three analysts currently cap their upside — and whether the put/call ratio remains near its year-high as the earnings date approaches or begins to unwind as hedges expire.
