StoneX (SNEX) amends Form 13F; restates $213.8M in holdings

Rhea-AI Filing Summary

StoneX Group Inc. filed an amended Form 13F (Amendment No. 2) restating prior quarterly reports after discovering under-reporting of holdings. The Form 13F Information Table lists 376 entries with a total value of $213,844,899, and names 2 other reporting managers.

The amendment attributes the errors to four causes across discrete periods: missing market‑making accounts, an Excel XLOOKUP vs SUMIF formula error, failure to implement a rounding rule change, and Excel scientific‑notation conversion of CUSIPs. Timing for the errors ranges from Q4 2021 through Q1 2025.

Insights

Compliance Officer

Restatement signals control weaknesses that were identified and corrected.

The filing documents an internal review and a formal restatement (Amendment No. 2) that increased reported holdings to a Total Value of $213,844,899 across 376 entries. The filing names specific causes and multi‑quarter date ranges, which supports traceability of the scope.

Remediation will hinge on procedural fixes: reconciliation of market‑making accounts, spreadsheet formula controls, adoption of the SEC rounding rule, and handling of CUSIP strings. Subsequent filings should show corrected tables and attestations of improved controls.

Operations / Data Risk Analyst

Errors reflect spreadsheet and data‑processing failure modes with quantifiable date windows.

The report details four technical failure modes (missing accounts, incorrect lookup function, rounding implementation gap, scientific notation conversion) spanning Q4 2021–Q1 2025. Each cause is tied to specific quarters, allowing targeted validation of corrections.

Key items to watch in follow‑on filings include reconciled CUSIP lists, corrected market‑making account inclusions, and disclosure that dollar‑value rounding aligns with the SEC rule change cited.

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.
