The Dow gained 103 points reaching 14 222.13, up 94 points and well past the previous intraday high of 14 198.10 set on October 11 2007, as investors continued a rally that has boosted the index by more than 8% so far in 2013.
Hugh Johnson, chief investment officer of Hugh Johnson Advisors, said the spike is good news for consumers in that it tends to lift spirits or raise confidence.

He added that since most of these companies have dividends that exceed what their bond yields are, from a rational standpoint it seems like a better investment in this environment.
Matthew Lifson, a currency trader at Cambridge Mercantile, said the question is, can the Dow maintain these levels?
"The market is interested in risk - that's why the Dow is higher, why the riskier currencies are higher. If you buy stocks, you want to be involved in all of this. And the only thing the sequester is doing right now is hurting air travel. It's not having much of an impact elsewhere."
The Standard & Poor's 500 index rose 12 points, also 0.8%, to 1 538. The S&P is also within striking distance of its own record close of 1 565. The Nasdaq composite gained 32 points, or 1%, to 3 213.62.
Stocks have rallied this year on optimism that the housing market is recovering and companies are slowly starting to hire again. Strong corporate earnings have also helped increase demand.
The market has also benefited from economic stimulus from the Federal Reserve and other global central banks. The US central bank is buying $85bn each month in Treasury bonds and mortgage-backed securities to keep long-term interest rates very low.
