NEW YORK (Reuters) - Leading global stock markets climbed on Thursday, fueled by a boost in bank and energy shares coupled with overall investor optimism after the recent passage of a $1.5 trillion tax cut plan in Washington.

Investors were hopeful the Republican-backed tax legislation, which slashes corporate income tax rates to 21 percent in the most dramatic overhaul of its kind in more than three decades, prompts companies to deploy additional capital on dividends, new projects and wages.

“There’s still the after-effects of tax reform being passed,” said Michael Antonelli, managing director at Robert W. Baird in Milwaukee. “I get the sense that the market is very optimistic about next year.”

Energy .SPNY and financial .SPSY stocks led gains among the 11 major S&P sectors. Energy, in particular, had underperformed in 2017.

The Dow Jones Industrial Average .DJI rose 55.64 points, or 0.23 percent, to close at 24,782.29, the S&P 500 .SPX gained 5.32 points, or 0.20 percent, to 2,684.57 and the Nasdaq Composite .IXIC added 4.40 points, or 0.06 percent, to 6,965.36.

MSCI's gauge of stocks across the globe .MIWD00000PUS gained 0.24 percent. The pan-European FTSEurofirst 300 index .FTEU3 rose 0.66 percent.

Solid economic growth data from the U.S. Commerce Department also helped boost stocks. The U.S. economy grew at its fastest rate in more than two years in the third quarter and was poised for a slight boost next year from the tax bill.
