This week begins with investors trying to do two things at once: enjoy the rally and pretend it is not watching the Strait of Hormuz every five minutes. U.S. stocks enter Monday's session after a strong prior week, with the Nasdaq up 2.4% and technology once again doing much of the heavy lifting. The S&P 500 is comfortably above where it stood before the latest Middle East conflict began, and Europe's Stoxx 600 has already climbed back above its late-February record.
