FOUR: Borrow Market Freezes as Calls Surge

Shift4 Payments is caught in a rare crossfire. Short interest sits at 24.9% of free float. Borrow availability has all but vanished. Yet options traders are piling into calls at the most aggressive pace in over a year.

The Borrow Market Has Closed

Availability on FOUR collapsed to 0.16% on June 24 — the tightest reading in 52 weeks. Only one share remained available for every 600 already borrowed. As of June 25, it has recovered marginally to 3.6%, but the signal is clear: this borrow market is essentially frozen.

Short interest rose 13.6% in a single day, reaching 24.9% of free float. The official FINRA figure, settled June 15, already showed 16.7 million shares short with 8.75 days to cover. The ORTEX daily estimate now puts shares short at 16.85 million. That's a meaningful build in a stock trading near $43.78.

The ORTEX short score stands at 79.7 — and has crept higher every session this week. The factor rank for utilization sits at 1 out of 100, the most extreme percentile possible.

Calls Are Dominating

The put-call ratio hit 0.477 on June 25. That's 2.78 standard deviations below the 20-day mean of 0.508. For context, the PCR had sat in a narrow band between 0.50 and 0.52 for most of the past six weeks. The break lower is abrupt.

The move came on the back of a 14% single-day rally on June 24. Options traders responded by loading calls — a sharp reversal from the steady, bearish positioning that had defined the prior month. The 52-week PCR low is 0.197, so there is room to run further toward call dominance.

Analyst Consensus Still Cautious

Loop Capital initiated coverage on June 25 with a Hold and a $40 target — below the current price. That's a pointed entry. Truist cut its target to $46 from $50 last month. DA Davidson and RBC both trimmed targets in May, though both kept bullish-to-outperform ratings.

The consensus sits at Hold. The mean price target is $60.14 — still 37% above current levels. But the recent initiation from Loop at $40 captures the bear view clearly: the stock is trading near fair value at best.

Founder Jared Isaacman bought nearly 388,500 shares in May alone, spending roughly $16 million combined across two purchases. Net insider buying over 90 days totals $18.2 million. That's a forceful counter-signal to the short conviction.
