Frequently asked TWST short volume questions

What is the daily TWST short volume?

As of May 15, 2026, Twist Bioscience Corporation (TWST) short volume is 511.5K shares against 1.0M total reported volume, or 50.49% short-side. Short volume measures shares sold short during the day; it is flow, not inventory.

How is TWST 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 TWST 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.
