The steady upward climb of the major U.S. indices on Thursday reflects the Fed's plans to pump money into the economy, on top of the fact the economy is already strengthening, said Ryan Detrick, senior technical strategist at Schaeffer’s Investment Research.
Detrick described it as a "double-dose of buying pressure."
Another driver behind the surge was the market's negativity ahead of a week filled with news, including the mid-term elections, the Fed's decision, and the nonfarm payroll report on Friday.
The expectation was that the market would sell off on the news, but when that didn't happen, the buyers stepped in.
"The market is the best indicator we know of for what the economy is going to do," Detrick said. "It's making a bet the economy will turn around in the next six to nine months."

But in a more positive sign for the economy, nonfarm productivity for the third quarter rose 1.9 percent, more than expected, while unit labor costs fell 0.1 percent, which was less than expected.
The Fed's decision to pump more money into the economy pushed the dollar to an 11-month lowagainst a basket of currencies on Thursday, giving a boost to industrial companies that sell goods abroad, where their products will be more competitively priced.

Meanwhile, the lower dollar drove oil prices higher. Oil surged more than 2 percent to more than $86 a barrel, a six-month high. Energy stocks were among the best performers on the S&P 500, including Halliburton , Schlumberger , Chevron , ConocoPhillips and ExxonMobil .
Monthly retail sales figuresfor October were largely better-than-expected, although warm fall weather muted sales in some categories. Some large department stores fared well, including Macy's , Saks and chain retailers Gap and Limited .
Kohl's and JC Penney's , however, didn't fare as well. Teen retailers also lagged, including American Eagle , Aeropostale and Hot Topic , although Zumiez's sales soared.
