U.S. stocks surged on Friday, lifting the Dow industrials and S&P 500 to record closes, after the Bank of Japan unexpectedly expanded stimulus, increasing hopes for the global economy.
"A lot of the fears that led to the selloff in the middle of October turned out to be unfounded, and U.S. interest rates are even lower than when we started, which makes the case for equities even stronger," said David Kelly, chief market strategist at J.P. Morgan Funds, referencing a 7.4 percent decline in the S&P 500 over a four-week period ending Oct. 15.
"Relative to where we were two weeks ago, we know earnings are going to be good, with 75 percent beating, which is the strongest since 2010, so it's a very good earnings season, and we didn't know that two weeks ago. Another part of it is good numbers for the U.S. economy, and then of course you have Japan, so the market had a lot of momentum going into today," Kelly said.
"So it's clear the selloff in the middle of October was unjustified," Kelly added.
The U.S. dollar climbed against the currencies of major trading partners, including the Japanese yen, while dollar-denominated commodities including gold and oil dropped sharply after the Bank of Japan increased its yearly target for monetary expansion to 80 trillion yen, or $724 billion, from as much as 70 trillion yen. The move comes in the same week the Federal Reserve said it would end six years of U.S. bond purchases.
"Although quantitative easing might be in the rear window for us here in the United States, it's present for Japan, and when you get something unexpected like this, you buy equities and sell commodities," said Art Hogan, chief market strategist at Wunderlich Securities.
"You could argue that Japan has more structural issues than monetary, but as you look around the globe, the market will most likely applaud when countries that have slowing economies do things to stimulate," said Hogan, who added the "ECB is probably the next up," referring to the European Central Bank.
