Frequently asked questions

What is CME's short interest?
As of the FINRA settlement date 2026-09-30, CME had 5.5M shares sold short — 1.6% of its float, with 3.2 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 CME?
In the last 12 months of SEC Form 4 filings, CME recorded 1 insider purchase and 4 sales reported on Form 4 (transaction codes P and S; grants and option exercises excluded). These are attributed public records — information, not instruction.
What do analysts say about CME?
The most recent action: Piper Sandler price_target on 2026-10-22. Rating actions are shown as published by the firms; they are not graded here.
Is this page telling me to buy or sell CME?
No. Everything on this page is descriptive, structural market context from public data, shown with its as-of dates. TradeAI News does not issue directional recommendations, price predictions, or buy/sell advice — for any ticker.
