Frequently asked MUIB short volume questions

What is the daily MUIB short volume?
As of Oct 14, 2026, Direxion Shares ETF Trust - Direxion MU Defined Income Boost ETF (MUIB) short volume is 255 shares against 386 total reported volume, or 66.06% short-side. Short volume measures shares sold short during the day; it is flow, not inventory.
How is MUIB 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 MUIB 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.
