Miami International Holdings Reports October 2026 Trading Results
Record year-to-date options activity contrasted with October year-over-year declines in options and equities daily volume.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Summary
Miami International Holdings (NYSE: MIAX) reported record year-to-date options average daily volume through October 2026, up 16.6% from the prior-year period. MIAX Exchange Group averaged 11.015 million contracts daily, with record year-to-date market share of 17.1%, versus 17.0% a year earlier.
October options daily volume fell 13.5% year over year to 11.290 million contracts but rose 5.4% from September. Monthly options market share was 16.9%, versus 19.4% a year earlier. MIAX Pearl equities daily volume declined 51.4% year over year to 106 million; its year-to-date daily volume fell 20.1% to 152 million. Agricultural futures daily volume rose 28.1% year over year to 9,333 in October, while year-to-date volume fell 17.0%. Financial futures daily volume reached 4,833, up 117.1% from September.
How this balance works
Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.
It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.
Rhea-AI Sentiment measures something else, the tone of the wording.
