The earnings result
Interactive Brokers reported earnings on 2025-01-21 for the fiscal quarter ending Dec/2024. Reported EPS of $2.03 compared with a consensus estimate of $1.86, a beat on the source's earnings measure.
An EPS comparison describes one part of the release. Revenue, segment performance, cash conversion, guidance and the conference-call discussion require the original company disclosures; the result alone does not establish why the stock moved.
