The announcement of a new contract with a major player like AT&T is a positive development for Ericsson, likely leading to increased investor confidence and a potential boost in revenue. This news directly impacts Ericsson and is significant for investors, hence the high relevance and importance scores. The confidence score is high due to the clear cause-effect relationship between contract announcements and stock price movements, although market conditions can always introduce variability.

While the news is primarily about Ericsson's stock movement, AT&T's involvement in a new contract suggests a positive outlook on its network expansion or improvement efforts, which could be seen favorably by investors. The relevance is slightly lower for AT&T as the news is more focused on Ericsson, but it still holds importance for AT&T's strategic direction. The confidence score reflects the indirect nature of the impact on AT&T compared to Ericsson.
