Insights

Insider Trading Analyst

TL;DR: Limited data; insider update looks immaterial.

The Form 4 simply records William Adams’s September 2024 ownership change. No share or dollar figures are disclosed, preventing assessment of scale or intent. While the nine-month reporting lag is notable, there is no indication of a large sale or purchase that might influence CXE’s valuation. On the information available, the filing has a neutral investment impact.
