X-FAB Silicon Foundries SE (XFAB.PA) stock: Winston Score, insiders and Congress trades

X-FAB Silicon Foundries is a semiconductor foundry, meaning it manufactures computer chips for other companies rather than designing its own. It specializes in analog and mixed-signal chips — the kind used in cars, medical devices, and industrial equipment — and counts automakers, medical device makers, and industrial companies among its main customers. X-FAB is one of the larger independent specialty foundries in the world focused on these non-digital chip types. X-FAB earns revenue by charging customers to fabricate chips in its factories, called fabs, located across Europe, the United States, and Malaysia. It operates as a pure-play foundry, so its business depends on customers outsourcing their chip production rather than building their own factories. The automotive chip market is its biggest growth driver, but that also creates risk — car production slowdowns or inventory corrections in the auto industry can quickly reduce demand for X-FAB's manufacturing capacity.
