US stock futures trimmed some losses yet stayed noticeably lower on Tuesday, with contracts for the three major indexes each dipping roughly 0.3%. This trend positions the S&P 500 and Dow Jones for what would be their fourth consecutive session of decline. Market participants are displaying caution in light of renewed anxieties around the high valuations in AI and technology stocks, particularly as Nvidia prepares to release its earnings report following the market close tomorrow. Nvidia's shares fell about 1% in premarket trading. Concurrently, investors are keenly monitoring the resumption of critical economic reports, which had faced delays due to the government shutdown. Notably, the US jobs report, anticipated on Thursday, is of particular interest amid concerns that its results may deter the Federal Reserve from proceeding with further interest rate cuts. In addition, the most recent data from the Labor Department disclosed that initial jobless claims were at 232,000 for the week ending October 18, with continuing claims rising to 1.957 million, marking the highest level observed since August. Both Home Depot and PDD Holdings, each set to release their quarterly earnings today, experienced declines near 0.9%.
