As of Apr 30, 2026, ProShares - UltraShort Nasdaq Biotechnology (BIS) fail-to-deliver quantity is 2.2K shares, with a 30-day average of 2.1K shares. The SEC publishes FTD data twice monthly: first-half data at month-end, second-half around the 15th of the following month.
What is the FTD aggregate net balance?

How do BIS FTDs affect options pricing?
Persistent FTDs flag hard-to-borrow conditions that distort put-call parity: in HTB names, synthetic long stock (long call + short put at the same strike) trades below the frictionless-parity price by approximately the borrow rebate. The discount equals the lending revenue forgone by holding the synthetic instead of actual shares. Reg SHO threshold-list inclusion follows from sustained FTD persistence.
