Rhea-AI Filing Summary

StoneX Group Inc. filed an amendment restating its Form 13F holdings after identifying under-reporting across multiple quarters. The amendment (Amendment No. 2) corrects the 13F Information Table totals to 346 entries with a value total of $245,304,775 and lists 3 other included managers.

The firm attributes the errors to four causes: missing market‑making accounts (Q4 2021–Q4 2024), an Excel XLOOKUP vs SUMIF formula mistake (Q1–Q4 2022), failure to implement an SEC rounding rule change (Q4 2022–Q1 2025), and Excel scientific‑notation conversion of CUSIPs (Q4 2021–Q1 2025). The filing is a corrective restatement of prior 13F reports.

Insights

SEC Filings Compliance Expert

Restatement corrects multi‑quarter 13F under‑reporting tied to data/rounding errors.

The amendment clarifies that the Form 13F Information Table now contains 346 entries totaling $245,304,775 and identifies three affiliated reporting managers. The firm traces the shortfall to omitted market‑making accounts, spreadsheet lookup/formatting errors, and a rounding rule implementation gap.

These issues are operational and disclosure‑process failures rather than new investment decisions; subsequent filings will show corrected historical holdings. Remediation likely requires data controls, reconciliation checks, and adherence to the rounding rule through Q1 2025.

During an internal review of StoneX Group Inc.'s Section 13(f) reporting practices we discovered the quarterly filings from Q4 2021 through Q1 2025 under-reported the total number of securities, shares and market values. The errors involved all Other Reporting Managers: StoneX Advisors Inc., StoneX Financial Inc., and Trust Advisory Group, Ltd. The review identified four main causes: 1. Missing Market Making Accounts; Between Q4 2021 and Q4 2024, three market making accounts were inadvertently excluded from the Firm's filings. 2. Formula Error in Excel; From Q1 2022 to Q4 2022, the Firm mistakenly used "XLOOKUP" functionality instead of "SUMIF" in Excel causing only the first instance of a CUSIP to be counted. 3. Failure to Implement Rule Change; SEC Rule 87 FR 38943 requiring all dollar values to be rounded to the nearest dollar, rather than to the nearest one thousand dollars, was not properly implemented from Q4 2022 to Q1 2025. 4. Excel Scientific Notation Error; Between Q4 2021 and Q1 2025, CUSIPs with an "E" were inadvertently converted into scientific notation in Excel. This led to the misidentification of certain reportable securities.
