Short Interest Reporting Dates

Upcoming reporting dates

Positions are measured on the settlement date, filed two trading days later, and published five trading days after that.

How the reporting cycle works

Positions are measured on two settlement dates a month, the fifteenth and the last day, each rolled back to the previous trading day when it falls on a weekend or a holiday. That makes twenty-four reporting cycles a year.

FINRA collects short interest twice a month and publishes it seven trading days after the settlement date it measures: firms have two trading days to file their positions and FINRA disseminates the file five trading days after that. In calendar terms the data is nine to twelve days old on the day it appears.

The dates on this page are derived from FINRA Rule 4560 rather than transcribed from a published list, so the publication schedule runs as far forward as you need it and cannot fall behind the list it was copied from. The release dates below, past and future, all come from that one rule.

What the report contains

Short interest is the number of shares sold short and not yet covered, as reported by the brokerage firms carrying the positions. It is a snapshot of one moment, not a running total, and it counts shares rather than traders or dollars.

Each record carries the short position at the settlement date, the position at the previous one, and the average daily trading volume FINRA used to derive days to cover. Days to cover is the position divided by that average volume: it is the number of days of ordinary trading it would take to buy back every shorted share, and it is the figure that makes a large position on a heavily traded stock comparable to a smaller one on a quiet stock.

The withdrawn proposal to report weekly

In May 2026 FINRA filed a rule change with the SEC, SR-FINRA-2026-012, that would have required short-interest reporting weekly rather than twice a month, widened the positions counted, and shortened the delay before publication. It would have cut the blind window between a measurement and its publication from roughly three weeks to about one.

FINRA withdrew that filing on August 5, 2026, before the SEC approved or disapproved it. The twice-monthly cycle above is therefore the schedule in force, and the dates on this page are not provisional. FINRA can file again, and this page was last checked against the SEC's rulemaking record on August 26, 2026.

• Most shorted stocks : every US stock ranked by short interest as a percent of shares outstanding, for any published settlement date.
• Largest short volume : daily short volume, which FINRA publishes every trading day rather than twice a month.
• Every stock page carries its own short interest history and an estimate for the settlement date FINRA has not published yet, at /stocks/{ticker}/short-interest.
