NEW YORK, Oct 31 (Reuters) - The Dow and S&P 500 ended at record highs on Friday and indexes posted strong gains for a second week after the Bank of Japan's surprise move to ramp up its stimulus program.
Major indexes also posted gains for the month, putting in a sharp recovery from their recent selloff that almost drove the S&P 500 into correction territory. The benchmark index is now up 8.4 percent from its Oct. 15 low and up 9.2 percent for the year so far.
The Nasdaq finished for the day at its highest since March 2000, while for the week the Dow rose 3.5 percent, its best percentage weekly gain since January 2013. The S&P 500 posted its best two-week gain since December 2011.
Gains were broad, with the benchmark S&P 500 index posting 126 new 52-week highs and the Nasdaq recording 229 new highs. Shares of Exxon Mobil, up 2.4 percent at $96.71, and Chevron, up 2.3 percent at $1119.95, were among the biggest positives on the Dow and S&P 500 after they reported results.
"The market technically went from violating moving averages to making new highs, and you get this surprise move out of the Bank of Japan, which is giving a little tailwind to the rally," said Eric Kuby, chief investment officer at North Star Investment Management Corp. in Chicago.
The move by the Bank of Japan, whose board voted to accelerate purchases of Japanese government bonds while tripling its purchases of exchange-traded funds and real-estate investment trusts, comes just days after the Federal Reserve wound down its years-long package of incentives.
That could help the outlook for stocks, especially if the U.S. economy keeps improving and earnings remain supportive.
The majority of S&P 500 companies are beating earnings expectations so far. With results in from 70 percent of companies, 75.8 percent are reporting earnings above analysts' expectations, according to Thomson Reuters data, well above the 63 percent average in the past 20 years.
The Dow Jones industrial average rose 195.1 points, or 1.13 percent, to 17,390.52, a record close. The Dow also hit an intraday record high of 17,395.54.
The S&P 500 gained 23.4 points, or 1.17 percent, to 2,018.05, a record close. The Nasdaq Composite added 64.60 points, or 1.41 percent, to 4,630.74.
For the week, the S&P 500 was up 2.7 percent and the Nasdaq was up 3.3 percent. For the month, the Dow was up 2 percent, the S&P 500 was up 2.3 percent and the Nasdaq was up 3 percent.
Among the day's biggest percentage gains, shares of Expedia rose 5.3 percent to $84.97 a day after it reported results. GoPro shares jumped 13 percent to $77.10 after forecasting better-than-expected holiday quarter sales.
The largest decliner on the Nasdaq was Starbucks, down 2.3 percent at $75.56, a day after it reported results.
About 8.1 billion shares changed hands on U.S. exchanges, compared with the 7.8 billion average for the month to date, according to data from BATS Global Markets.
Advancing issues outnumbered declining ones on the NYSE by 2,363 to 717, for a 3.30-to-1 ratio on the upside; on the Nasdaq, 1,921 issues rose and 816 fell for a 2.35-to-1 ratio favoring advancers.
