Frequently asked questions

What is IRIX's short interest?
As of the FINRA settlement date 2026-09-30, IRIX had 132K shares sold short — 1.2% of its float, with 3.5 days to cover at average volume. FINRA publishes this data roughly two weeks after each twice-monthly settlement, so it is inherently delayed. A short-interest figure describes an aggregate position; it does not predict what the stock will do.
Are insiders buying IRIX?
In the last 12 months of SEC Form 4 filings, IRIX recorded 50 insider purchases and 0 sales reported on Form 4 (transaction codes P and S; grants and option exercises excluded). 2 filings not counted: the filed price could not be checked against the U.S. listing. These are attributed public records — information, not instruction.
