Overview
- U.S. indexes climbed to fresh highs with the Dow closing above 53,000, a run driven by strong demand for AI-related chipmakers that pushed the Nasdaq and S&P higher after the long holiday weekend.
- Chip and memory names stabilized and partly rebounded in early July after a late‑June rout, but profit‑taking hit Seoul when Samsung reported an extraordinary jump in Q2 operating profit and its shares fell.
- South Korea’s SK Hynix launched a major U.S. listing planned to raise about $28–29 billion, a large supply event that will test investor appetite for AI-linked chip companies on Nasdaq.
- Bank of America and other analysts warned that speculation and concentration in a few high‑multiple AI names raise the risk of a valuation 'snapback,' and several firms compared the episode to past concentrated bubbles.
- Markets are focused on the Fed’s June meeting minutes due this week and on Q2 earnings for validation of the rally, while OPEC+ output increases have eased oil prices and slightly reduced near‑term inflation pressure.
