US stocks set a record closing high on Tuesday, buoyed by semiconductor and memory stocks with sentiment improving broadly as the US-Iran ceasefire appeared to hold.

The S&P 500 Index rose 0.8% as Micron Technology Inc., Sandisk Corp. and Intel Corp. all advanced more than 11%, pushing the benchmark past Friday’s prior historic close.
