Frequently asked OPEN short volume questions
- What is the daily OPEN short volume?
- As of Jun 30, 2026, Opendoor Technologies Inc. (OPEN) short volume is 36.6M shares against 65.8M total reported volume, or 55.53% short-side. Short volume measures shares sold short during the day; it is flow, not inventory.
- How is OPEN short volume reported?
- FINRA publishes the Daily Short Sale Volume File for trades reported to FINRA TRFs and the FINRA/Nasdaq ADF on a T+1 basis. The headline figure is the count of shares that printed at the short-sale or short-exempt tick across all reporting venues for the symbol; each exchange separately publishes its own daily short-sale data file.
- What does OPEN short volume tell options traders?
- Daily short-sale flow is one input that helps disambiguate dealer-hedging activity from directional bear flow when the chain shows fresh customer call inventory. It is not a clean MM-only proxy: the headline number mixes directional shorting, options-MM delta-hedging, ETF-creation arbitrage, and convertible-arb hedging. Cross-check against gamma-exposure and OI changes for a cleaner read.
