Why this matters — Three distinct ORTEX data streams have aligned simultaneously on CVBF: short interest has collapsed, cost to borrow has doubled, and options sentiment has swung to a 52-week bullish extreme. That combination of signals on a single regional bank in one week is unusual.
Short interest collapses. Shares short in CVBF fell 25.6% in one week. The position dropped from 13.9M shares on April 20 to 8.4M by April 24. Short interest as a percentage of free float now stands at 6.16%, down from 8.3% just days earlier. Utilization has also dropped sharply — from 17.4% on April 20 to 7.35% on April 24, far below the 52-week high of 19.8%.
Cost to borrow doubles. Despite the short-covering, the cost to borrow surged 100% over the past week. CTB rose from 0.45% to 0.90% APR. Short supply is tightening even as the gross short position unwinds — borrowing what remains is getting more expensive.
Options sentiment hits a 52-week low put/call ratio. The put/call ratio plunged to 0.22 on April 27. That is 2.49 standard deviations below the 20-day mean of 4.92. It is the lowest PCR reading in 52 weeks. Calls are heavily dominating options flow, marking a sharp reversal from the elevated put-heavy positioning seen through most of April.
Piper Sandler raised its price target on CVBF to $27 on April 27 — the same day the PCR hit its 52-week low. The firm kept its Overweight rating. The stock trades at $20.34, leaving roughly 33% upside to that target. State Street added 755,185 shares in its most recent filing. FMR (Fidelity) added 884,800 shares. Both are notable additions among the top holders. The ORTEX short score has dropped from 62.9 to 47.2 over the past week, reflecting reduced short-side pressure.
The short interest spike to 13.9M shares on April 20 reversed almost entirely within four trading days. The last time utilization hit similar highs (19.8% on April 1) it also faded quickly. The current episode is more abrupt and more aggressive than that prior move.
