That said, Carson agreed that tech remains one of the best sectors for investors and also sees among his clients that health care is becoming a larger percentage of holdings.
"Health care has not been this popular before, but as we see more baby boomers getting older and requiring more health care, we will see more interest," Wynn said. "All these boomers are turning 60 and 70, and health care will go up and be good investments."
"A millionaire having a hip replacement is going to ask as an investor, 'What's this all about?'" Altfest said.
Carson parted ways with millionaires in this survey over energy, believing it a good value play with prices where they are (and while there will be more pain, the larger players will consolidate, and lower prices will bring higher prices eventually). He recommended that investors dollar-cost average into energy, at a level of up to 10 percent of their portfolio, but only 1 percent a month over the next year to smooth out the volatility.
Altfest said it doesn't surprise her that the millionaire survey results show a lack of interest in Europe and emerging markets as value plays, but she thinks millionaires are wrong.
"We don't really think most people want to hear it, but we find value in Europe, and we think people should be more open to emerging markets and stocks abroad," she said. Her firm has a more sizable percentage of investments abroad, and for U.S. investors, she said it will be not as expensive to invest abroad as to continue to invest in U.S. stocks.
Carson noted that his firm's global portfolio has been a bright spot this year with the U.S. market being flat, but he sees millionaires seizing upon real estate ownership as one of the most interesting opportunities for investors. The CNBC Millionaire Survey found 71 percent of investors claiming their top holding was outside a single stock.
Carson's firm bought and rehabbed individual homes, and that investment is up 19 percent year-to-date, with an 11 percent dividend yield. However, it's an illiquid investment that requires a five- to six-year holding period. "If you can give up daily liquidity, you'll get a better return," Carson said.
