The Dow and S&P closed at record highs on Thursday after the Fed eased concerns that the central bank could initiate its first rate hike before the summer. The markets had also been awaiting the results of a Scottish independence vote.

BTIG's chief strategist Dan Greenhaus raised his year-end price target for the S&P 500 to 2,075-2,100, up from his earlier target of about 1,980, and increased his 2015 EPS estimate to $125. This would imply a price appreciation of 13.6% for 2014, leaving the index trading at 16.8x his 2015 EPS estimate.

"We have been unapologetically bullish for some time now, but as we approach the year's final quarter, some 'catch-up' is necessary," said Greenhaus. "Given the underperformance of so many and the seasonal bias that dominates the winter months, the bias remains to the upside for equities in the coming three months. However, we temper this enthusiasm by noting the Federal Reserve's shift from policy accommodation to policy tightening is likely to lead to equity weakness, no matter how temporary it may be."

European stock indices rose on Friday after a strong day of trading in Asia and as Scotland rejected independence from the rest of the U.K. The Scots voted about 55% to 45% to stay with the United Kingdom but the Scottish parliament will receive significant devolved powers from Westminster as a result of the referendum. The FTSE 100 rallied 0.72% and the pound was down 0.06% vs. the dollar after an initial surge on Scotland's "no" vote. In Frankfurt, the DAX surged 0.83%.

In China, news that Alibaba Group had raised $21.8 billion galvanized indices.
