BP stock climbed nearly 1% on Tuesday. Yet options traders are quietly loading up on protection.
The put/call ratio hit 0.58 on April 29 — a z-score of 2.5 against the 20-day mean. That's the most cautious options positioning in two weeks, and the sharpest statistical deviation BP has seen recently. It sits well above the 20-day average of 0.51, though still below the 52-week high of 0.72.
Short shares rose 13.9% over the past week to 10.5 million. The one-month increase is 16.1%. That's a meaningful build — and it arrives alongside a cluster of bullish analyst moves, creating a tug-of-war between upgraders and skeptics.
UBS upgraded BP to Buy on April 15. Scotiabank raised its price target from $41 to $58 on April 22, maintaining Sector Outperform. Wells Fargo lifted its target to $54 from $39 earlier in April. These are substantial target increases. Yet short sellers have responded by adding, not retreating.
The cost to borrow has swung sharply in recent days. It dropped to 0.03% on April 24 before rebounding to 0.15% by April 28 — a 62% one-week rise. Despite the noise, the absolute level remains extremely low. The one-month change is actually down nearly 50%.
Availability in the lending pool remains very wide. The borrow market is not tight. Short sellers face no real friction adding positions at current rates.
The ORTEX short score sits at 27.3 — well below the danger zone. The short score rank is at the 92nd percentile of its own history, meaning the signal is elevated relative to BP's own baseline, but the absolute score does not indicate acute squeeze pressure.
Three major upgrades arrived in six weeks. Norges Bank trimmed 35.4 million shares. But BlackRock added 21 million, Amundi added 69.3 million, and Nomura added 101.5 million. Net institutional flow looks broadly constructive.
BP's ESOP shed 94 million shares — by far the largest single change in the holder table. That's worth watching but likely reflects plan mechanics rather than directional conviction.
BP next reports earnings on August 4.
