A disappointing Friday employment report helped send stocks down further, with cruise operators hammered

U.S. stock indexes have held up pretty well since the U.S. and Israel launched attacks Iran on Feb. 28, but 79% of stocks in the S&P 500 were down for the week, as of Friday morning.

Since the U.S. and Israel began their barrage against Iran’s government on Feb. 28, U.S. stocks on the whole had held up rather well through Thursday, with the S&P 500 down only 0.7%. But on Friday there was more bad news for investors.

Early on Friday the Bureau of Labor Statistics released its Employment Situation Summary for March, with nonfarm U.S. payrolls declining by 92,000. Economists polled by the Wall Street Journal had expected the U.S. economy to add 50,000 jobs during March.
