Frequently asked VLO short volume questions
- What is the daily VLO short volume?
- As of May 15, 2026, Valero Energy Corporation (VLO) short volume is 296.4K shares against 749.1K total reported volume, or 39.56% short-side. Short volume measures shares sold short during the day; it is flow, not inventory.
- How is VLO 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 VLO 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.
