Fails to deliver

The SEC's fails-to-deliver figure for EFRA: the aggregate net balance of shares that failed to be delivered at each settlement date, published by the SEC twice a month and shown here verbatim for the trailing window. A balance is not a daily flow, and a fail has many ordinary causes; the SEC says it cannot guarantee the accuracy of the data. See what fails to deliver are and the largest balances today.

Questions

Frequently asked questions

What is EFRA's short interest?
518 shares short for settlement date 15 Sep 2026, per FINRA's consolidated short interest report, down 531 from the previous settlement.
Why is there no percentage for EFRA?
Because no defensible share count exists to divide by: no SEC filer maps to the symbol (funds, notes, preferreds, warrants and foreign listings). No SEC filer maps to this symbol in EDGAR's ticker file. That is the normal case for funds, exchange-traded notes, preferred shares, warrants, units and foreign listings, none of which file a share count we could divide by.
What is EFRA's days to cover?
1.00 days for settlement date 15 Sep 2026: FINRA's own short interest ratio, the reported shares short divided by average daily trading volume, published in the same file and shown verbatim. We hold no volume data ourselves.
Is this the short float?
No. This page shows FINRA's share count only. Short float divides that count by the public float, and short interest as we publish it elsewhere divides it by shares outstanding from SEC filings. Neither denominator is available for this line, so neither ratio is shown.
How often does this update?
FINRA member firms report short positions as of the 15th and the last business day of each month, and FINRA publishes the consolidated figures about nine business days later. We ingest each file the day it appears and re-read recent settlements for revisions.
