1 insider bought €139k of shares over the last 90 days, the latest filed 11 Aug 2026.
StoneX Group Inc., founded in 1981, is a Finance & Banking company based in United States. Its directors and officers file their transactions with SEC (Form 4). From 18 October 2025 to 18 October 2026, the disclosure feed for StoneX Group Inc. logged 115 filings by 23 insiders.
Purchases and sales both appear in the filings: 2 purchases (2 insiders, €222k) and 29 sales (8 insiders, €57.4M). The totals exclude 2 filings filed without an amount. Unlike grants, an open-market purchase is paid for by the insider, at the market price. One trade stands out by size: a sale of €6.8M from Oconnor Sean Michael, disclosed on 23 July 2026, or 0.097% of market capitalisation. Those buying include 1 board member and 1 senior executive.
The most recent open-market purchase was published on 11 August 2026, 68 days ago. The median gap between a trade and its publication by SEC (Form 4) is 2 days. For comparison, the SEC allows two business days to file a Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify.
Compared with its exchange (5,458 companies, median 22 filings), a count of 115 filings is above the norm. Our records for StoneX Group Inc. go back to 2016, with 19 purchases and 107 sales on the open market in total. For the fiscal year to 30 September 2025, the annual 10-K puts revenue at 132.38 bn USD and net income at 305.9 m USD.

StoneX Group Inc. (ticker SNEX) is a U.S.-based financial services company listed on the NASDAQ market in the United States. For French-speaking investors in France, Belgium and Switzerland, StoneX stands out as a global market-access and risk-management intermediary, combining execution, clearing, post-trade services, market intelligence and specialized client coverage. Founded in 1924, the company has evolved from a commodities-hedging business into a diversified multi-asset financial network. It rebranded to StoneX in 2020 to better reflect a more unified, international platform. Its headquarters are in New York City, placing it at the center of the U.S. financial ecosystem and close to major capital-markets clients.
StoneX is organized around four operating segments: Commercial, Institutional, Self-Directed/Retail, and Payments. The Commercial business serves clients seeking hedging and execution solutions across commodities, agriculture and broader market-risk exposures. Institutional provides professional clients with fixed income, foreign exchange, equities, derivatives and prime brokerage capabilities. Self-Directed/Retail focuses on individual investors through trading and market-access platforms. Payments delivers cross-border payments and FX solutions, which is an increasingly important revenue stream given international trade and treasury flows. This mix gives StoneX a diversified operating model, but it also means results can be sensitive to trading volumes, volatility, client activity and regulation.
From a competitive perspective, StoneX is a scaled specialist rather than a universal bank. It competes through breadth of product, execution quality, clearing infrastructure, and deep client relationships in complex markets. The company emphasizes a large global footprint across six continents and a broad client base spanning commercial users, institutions, and retail investors. In recent years, acquisitions have been a key driver of growth and capability expansion. Most notably, StoneX highlighted the acquisition of R.J. O’Brien as a transformational transaction that made it the largest non-bank FCM in the United States. In 2025, the company continued to expand through targeted deals and integrations, including Octo Finances in Europe, The Benchmark Company to strengthen investment banking capabilities, and additional moves in wealth management, fixed income and trading-related businesses. For investors, the key thesis is a diversified, acquisition-led financial franchise with meaningful scale, but one that remains exposed to market conditions, transaction volumes and execution risk.
