ShortVolume.com is a widely used resource for daily short volume data, offering a raw feed of short selling activity across exchanges. DilutionWatch is built for investors who need to understand not just how much a stock is being shorted, but whether the short thesis is structurally safe — or sitting on a powder keg of warrant overhang, shelf offerings, and FTD accumulation. This comparison examines where each platform fits in a short thesis workflow.
Short volume data tells you what traders are doing. DilutionWatch tells you whether they should. FTD data + short squeeze risk + cash runway + warrant overhang = a complete picture of whether a short is clean or dangerous — and no other platform combines all four signals in one place.

For Short Thesis Validation: DilutionWatch Is the Missing Layer
ShortVolume.com provides raw short volume feeds that are genuinely useful for tracking market activity. DilutionWatch adds everything short sellers need to validate whether a thesis is structurally sound: FTD data, warrant overhang, shelf capacity, cash runway, and a scored risk system with 1.96M historical records.
The Verdict
ShortVolume.com and DilutionWatch serve complementary roles in a short thesis workflow. Use ShortVolume.com to monitor daily short volume by exchange and identify unusual short selling patterns. Use DilutionWatch to answer the structural question: is this company positioned to dilute its way out of a short squeeze, and how much runway and warrant overhang could burn the short position?
The combination is particularly powerful for small-cap and OTC traders. A high short volume reading on ShortVolume.com paired with a high DilutionScore on DilutionWatch signals a structurally dangerous short — the company has both the motive and the mechanism (shelf registrations, ATM programs, convertible notes) to dilute and escape short pressure.
DilutionWatch's FTD integration — sourced directly from SEC and FINRA public disclosures — surfaces settlement failures that often precede forced covering events. No other platform combines FTD, dilution scoring, and real-time SEC alerts in a single view without requiring a Bloomberg terminal or institutional data subscription.
