Stocks closed out the week with strong gains, with the Dow and S&P 500 hitting fresh highs and all three major averages logging their fourth-straight weekly advance, boosted by a pair of positive economic reports.
The S&P 500 closed at 1,667, spiking nearly 150 percent since the financial crisis when the index hit a low of 666.79 on March 6, 2009.
The Dow Jones Industrial Average rallied 121.18 points, or 0.80 percent, to close at 15,354.40, led by Boeing and JPMorgan.
The S&P 500 jumped 17 points, or 1.03 percent, to end at 1,667.47. The Nasdaq advanced 33.73 points, or 0.97 percent, to finish at 3,498.97. The CBOE Volatility Index (VIX), widely considered the best gauge of fear in the market, finished below 13.
For the week, the Dow soared 1.56 percent, the S&P 500 gained 1.98 percent, and the Nasdaq added 1.82 percent. Cisco led the top Dow gainers, while Intel edged lower.
The S&P 500 & Nasdaq have each had gains of at least 1 percent in each of the last four weeks. The last time that happened for the S&P was back in October 2011 and the last time the Nasdaq rose at least 1 percent for four-straight weeks was in February 2012.
All key S&P sectors finished in positive territory for the week, led by financials and industrials.
"Individual economic data points can be volatile, but the average slope of the trend is positive," said Lawrence Creatura , portfolio manager and Clover Small Value Fund at Federated Investors. "Things are improving at a slow rate, but if it continues, there's a link between the fundamental sand the stock market performance…there's a logical reason why prices have been increasing."

On the economic front, consumer sentiment gained in May to the highest level since July 2007, according to the Thomson Reuters/University of Michigan index. And leading indicators rose in April, hitting its highest level in nearly five years, according to the Conference Board, suggesting an anticipated growth slowdown would be temporary.
Adding to positive sentiment, JPMorgan boosted its its year-end price target for the S&P 500 to 1,715, sharply above the bank's original expectation of 1,580, which the index crossed above last month. So far in 2013, the index has surged more than 15 percent.
"The timing of an increase in the target is not ideal as equity prices hover near highs," wrote Thomas Lee, JPMorgan's chief market strategist. "On the other hand, we do not believe investors should be paring their holdings."

"The uncertainty caused by the Fed's discussion of an exit could create volatility, but the reality is that when it happens, it will occur simultaneously with economic improvement," said Creatura.
Thursday's comments by the Fed's John Williams and Charles Plosser suggested they were both open to reducing asset purchases in the near-future.
So far, 93 percent of S&P 500 companies have reported quarterly results, with 67 percent of firms topping earnings expectations and 24 percent missing forecasts, according to the latest data from Thomson Reuters. If all remaining companies report earnings in line with estimates, earnings will be up 4.8 percent from last year's first quarter.
Meanwhile, sales have come in 1 percent on average.
Data analysis software maker Tableau Software skyrocketed more than 50 percent in their trading debut, valuing the company at $2.82 billion. Interest in data visualization software makers has increased after the successful debut of Splunk in April 2012.
A year since its IPO, social-networking giant Facebook remained the worst performer on the Nasdaq 100. The stock is still down more than 30 percent from its IPO price of $38 a share.
