A survey of affluent investors by research firm TNS shows that the TNS Investor Confidence Index rose to 116 in October, its highest level since hitting 129 in 2007. Its lowest point was 81 in October 2008.

Despite only modest economic and job growth, TNS said, affluent investors are feeling more confident about how their own investments and the broader U.S. stock market will perform over the next six months.

“This increase corresponds with substantial increases in the stock markets, with the Dow Jones, S&P and Nasdaq averages each rising 10% between Aug. 26 and Oct. 18,” said TNS Senior Vice President Ellen Sills-Levy.

While the largest percentage, 19%, said they plan to invest in fixed income, 15% said they are ready to make more international investments, followed by 11% citing commodities and 10% real estate.

The most recent TNS Investor Confidence Index reading is based on online interviews with 3,936 investors who have total investable assets of $500,000 or more.
