Louis Navellier comments on the "wall of worry" that investors have recently learned to shrug off.
"The S&P 500 fell 1.14% last week, but it rose 2.08% for the month of May, defeating the “Sell in May” theory this time around. The index is up over 14% for the year so far, but the last hour of trading in May was a downer, with stocks falling about 1% in the last 30 minutes before the close. Still, I am impressed that the market was able to shrug off the steep (5%) correction in Japan’s stock market on Thursday. It seems that we’ve finally realized we don’t have to catch a cold when other markets sneeze."
