Actionable Insight ▼ Bearish

Executive Summary

Two top Teradata executives, including the CEO and COO, sold a combined $1.74M in open-market sales on the same day (Sept 15, 2026). The CEO's sale of $300K is modest, but the COO's $1.44M sale is significant. This cluster of open-market selling by the two most senior officers is a bearish signal, especially given the company's poor historical stock performance and the lack of any disclosed 10b5-1 plan context.
