Nasdaq Composite

The provided news articles do not mention the Nasdaq Composite. Therefore, it is impossible to provide a summary about its current newsworthiness, recent events, or significance based solely on this information. The articles primarily discuss European stock markets reacting to potential conflict resolution in Iran, the Dow Jones Industrial Average reaching a milestone, and the decline in Bitcoin's value. Without any mention of the Nasdaq, any attempt to describe its current state would be speculative and inaccurate.
