High-net-worth investors expect market conditions to improve and plan on increasing their equity positions in 2013, according to a Fidelity survey.

The 1,510 high-net-worth investors who participated in the survey—all with $250,000 or more in investable assets—expect market conditions to improve and nearly half plan on increasing their equity positions in 2013. Sixty-five percent said U.S. stocks are the asset class they expect to invest in the most.

High-net-worth investors expect improved performance in 2013, with 38 percent expecting to beat market averages this year. Just 15 percent expect performance to fall below market averages—an improvement over  33 percent in 2012, according to Fidelity.

Nearly half of investors expect to increase their equity holdings by an average of 8 percent this year, according to the survey, and almost 40 percent of high-net-worth investors will keep them at current levels.

U.S. stocks led the list of investment options, with 65 percent of respondents indicating they plan on investing in U.S equities over foreign equities and corporate bonds, according to Fidelity. Investors believe that mid- and large-cap equities offer the best upside potential.

Over three quarters of high-net-worth respondents expressed concern regarding the impact of inflation on their portfolios. Their main tactic to hedge against inflation is to increase their equity allocation, followed by seeking higher yielding bonds. According to Fidelity, increases to income and capital gains taxes are also a cause of concern for high-net-worth investors.

Fidelity Investments conducted the survey via a live webcast provided by On24 on March 5.
