July 3 (Bloomberg) -- Developing countries’ share of worldwide equity value climbed to a record as the fastest- growing economies lured investors amid the first global recession since World War II. The 22 nations classified as “emerging” by index provider MSCI Inc. comprise 24 percent of world market capitalization, up from 18 percent at the start of this year, the highest proportion since Bloomberg began compiling the data in 2003. China shares surpassed $3 trillion yesterday for the first time since August, from $1.8 trillion at the end of 2008. The increase signals growing confidence in developing countries as equity investors, spurred by interest-rate cuts and stimulus plans, redeploy cash after the worst U.S. losses last since the Great Depression. The MSCI Emerging Markets Index rose 35 percent, beating a 2.9 percent advance in the MSCI World Index of developed economies and lifting the value of stocks to $8.5 trillion from $5.1 trillion in 2008
