Stocks closed near session highs Thursday, with the Dow logging its first 10th-straight winning streak for the first time since 1996 and the S&P 500 within a hair's breadth of its all-time closing high, lifted by a better-than-expected jobless claims report.
"This could be the greatest bull run since the '80s only because there's nowhere else for investors to go," said Alan Valdes, director of floor operations at DME Securities. "The Fed's pumping $85 billion a month into the market so there's no way for it to go down, but everyone's got their finger on the trigger because they don't know when this is going to turn."
The Dow Jones Industrial Average gained above 14,500 for the first time, and logged its 10th consecutive rally. Cisco and Verizon led the gainers.
The blue-chip index is up 10 percent so far in 2013, on track to logging its best first-quarter performance since 1998. Historically, a strong first quarter indicates robust gains for the year. Since 1950, there have been only 12 other instances where the Dow was up more than 8 percent in the first quarter and in each of those years, the index finished positive 100 percent of the time.
The Dow Jones Industrial Average rallied 83.86 points, or 0.58 percent, to end at 14,539.14. Hewlett-Packard and IBMled the gainers, logging its first 10th-consecutive winning streak for the first time since November 1996. The S&P 500 rose 8.71 points, or 0.56 percent, to close at 1,563.23 -- just short of its all-time closing high set in 2007. The Nasdaq gained 13.81 points, or 0.43 percent, to finish at 3,258.93.
The CBOE Volatility Index (VIX), widely considered the best gauge of fear in the market, ended near 11, falling to a six-year low.
Among key S&P sectors, telecoms and techs led the gainers.
