The stock market is experiencing cautious optimism as the Dow and Nasdaq open with the S&P 500 reaching 6,000 points for the first time since February. This milestone comes as U.S. and Chinese negotiators meet to discuss economic issues. Tesla shares are declining, impacting market sentiment. Analysts note that the S&P 500 is within 3% of a new high, but traders are searching for an ‘elusive’ catalyst to push it further. Despite the positive movement, caution is advised for buyers given the current market dynamics. — new from MarketWatch
