NEW YORK, June 20 (Xinhua) -- U.S. stocks closed up Friday to wrap up the week on a positive note, with the Dow Jones Industrial Average and the S&P 500 breaking new ground, boosted by optimistic sentiment sparked by the U.S. Federal Reserve's commitment to an accommodative monetary policy.
The blue-chip index hit a record high of 16,978.02 points in intraday trading, within a striking distance of the psychologically important level of 17,000 points, before finishing at a record close of 16,947.08 points, up 25.62 points, or 0.15 percent.
The S&P 500 also touched a fresh record intraday high of 1,963. 91 points, extending its record rally into a third straight session. The broader index ended at 1,962.87 points, up 3.39 points, or 0.17 percent.
Both the Dow and the S&P 500 logged a six-day winning streak.
The tech-heavy Nasdaq Composite Index gained 8.71 point, or 0. 20 percent, to 4,368.04 points, a 14-year high.
Wall Street regained steam in the week, with the three indices jumping 1.0 percent, 1.4 percent and 1.3 percent, respectively, as investors increased appetite for risky stocks, cheering dovish remarks from Fed Chair Janet Yellen following the close of the U.S. central bank's two-day policy meeting Wednesday.
Yellen downplayed concerns about rising inflation, saying the recent uptick in consumer prices is "noisy," while emphasizing the Fed has no set timing for interest rate hike which depends on economic data.
The Fed announced Wednesday that it will continue to taper its monthly bond purchases by another 10 billion U.S. dollars next month and lowered its U.S. growth forecast for this year, while pledging to keep its benchmark short-term interest rates near zero "for a considerable time" after the bond purchase program ends.
In absence of major data coming out in the day, investors continued to digest the Fed's latest move to foster the U.S. economy in a context of anchored inflation and Yellen's dovish policy stance.
