Why this matters — Three distinct ORTEX data points have converged on WMB within 48 hours. Short interest, cost to borrow, and options sentiment are all flashing simultaneously — a rare alignment that warrants attention.
Cost to borrow surges. WMB's borrowing cost jumped 66% over the past week to 0.43%. The spike signals tightening availability of shares to short. Utilization climbed to 0.62%, up from 0.50% a week earlier. Borrowing costs remain volatile, hitting 1.48% as recently as April 6th before retreating.
Short interest climbs steadily. Shares shorted rose 20% over the past month to 16.3 million. That represents 1.34% of the free float. The build has been gradual but persistent. Short interest stood at just 13.5 million shares in mid-March. The latest official FINRA reading shows 16.1 million shares short as of March 31st — confirming the trend.
Options sentiment turns bullish. The put-call ratio dropped to 0.57, down sharply from its 20-day average of 0.65. The current PCR is nearly three standard deviations below recent norms, indicating unusually strong call buying. Traders are positioning for upside even as short sellers add to their bets.
WMB has not seen this specific three-way convergence in the recent dataset. The last time utilization exceeded 1% was mid-March, when short interest also spiked. That episode resolved quickly. The current build is more measured but also more sustained.
