Compx International Inc: what insiders have been doing
Compx International Inc is a Industry company. Its directors and officers file their transactions with SEC (Form 4). Over the twelve months to 22 October 2026, 17 filings were filed, from 9 insiders.
There is no open-market purchase to report; the filings show 8 sales worth €38k by 1 insider. At €20k, the sale published on 12 August 2026 by Manix Ann is the largest of the period (0.0050% of market cap).
Across the 2,023 companies tracked on its exchange, the median is 41 filings; at 17 filings, this issuer sits below that mark. Over the whole record (from 2016), the tally stands at 33 purchases and 17 sales. On the fundamentals side, the SEC filing (10-K) for the period ending 31 December 2025 lists revenue at 158.3 m USD and net income at 19.5 m USD; the dividend was 0.30 USD per share.
The median gap between a trade and its publication by SEC (Form 4) is 1 day. 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.
In the same sector, recent insider purchases at Tennant Co and Accelevation Holdings Corp. also feature in our signals. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.

About Compx International Inc
CompX International Inc. (NYSE American: CIX) is a U.S.-based industrial components company focused on security products and specialty components for recreational transportation and related end markets. Incorporated in Delaware in 1993 and headquartered in Dallas, Texas, United States, CompX is best understood as a niche manufacturer rather than a broad-based industrial conglomerate. Its business model is built around engineered products sold to professional customers who value reliability, durability, specification compliance, and long product life cycles. ([sec.gov](https://www.sec.gov/Archives/edgar/data/1049606/000110465926023463/cix-20251231x10k.htm?utm_source=openai))
CompX’s operations are organized around two main product areas: security products and recreational marine components. The security products line includes locks, locking mechanisms, and related hardware used in postal applications, office and institutional furniture, cabinetry, tool storage, healthcare applications, and other industrial uses. The company describes its offerings as being designed principally for medium- to high-end applications where design, quality, and durability matter. That positioning supports a differentiated niche strategy, but it also means CompX competes against lower-cost manufacturing sources and is exposed to shifts in customer mix, materials costs, and end-market demand. ([sec.gov](https://www.sec.gov/Archives/edgar/data/1049606/000110465926023463/cix-20251231x10k.htm?utm_source=openai))

From a competitive standpoint, CompX holds a specialized role in a fragmented market. Its long operating history and focused product portfolio provide some defensibility through know-how, customer relationships, and manufacturing standards. The company is also notable for its ownership structure: as of year-end 2025, CompX was approximately 87% owned by NL Industries, itself part of the broader Valhi/Contran ownership chain. That concentrated control can offer strategic stability, but it also limits free float and can reduce the company’s profile among generalist investors. Importantly, CompX trades on NYSE American under the ticker CIX, not on the main NYSE or NASDAQ market. ([sec.gov](https://www.sec.gov/Archives/edgar/data/1049606/000110465926023463/cix-20251231x10k.htm?utm_source=openai))
Geographically, the business remains primarily U.S.-centered, with Dallas serving as the corporate base and most investor-relevant disclosure coming through SEC filings. Recent developments in 2026 included the release of full-year results and a regular quarterly dividend declaration, which underscore a capital-allocation framework oriented toward consistency and shareholder returns rather than aggressive expansion. For French-speaking investors in France, Belgium, or Switzerland, CompX can be viewed as a small-cap industrial specialty name with a conservative operating profile, limited market liquidity, and a focus on mature, technically demanding end markets in the United States. ([sec.gov](https://www.sec.gov/Archives/edgar/data/1049606/000104960626000003/cix-20260304x8k.htm?utm_source=openai))
