More working investors say their greatest financial worries are rising health-care costs, changes to Social Security and/or Medicare, and running out of money in retirement, shows a survey for Signator Investors.

Fifty-five percent of non-retired investors cited the financial risk of rising health-care costs in retirement as their greatest concern, a seven-point jump from last year’s survey.  Overall, 89 percent of this year’s respondents expressed some concern about rising health-care costs.

“Though being able to afford health care isn’t a new issue, the fact that more affluent workers are very worried about it than not, points to the value advisors can provide to help clients develop strategies to manage it,” said Matt Rigatti, vice president, Signator Investors Inc.

Seventy-three percent of non-retired investors who have advisors said they felt it was important that their financial professional posess special retirement income certification, said Rigatti.

Changes to Social Security and/or Medicare was the second most-cited financial risk with 34 percent of respondents citing they were "very concerned,’" up slightly from 32 percent last year. Overall, 74 percent of respondents cited some level of concern about this risk.

Running out of money in retirement was cited as the third financial risk investors were concerned about. It increased slightly in 2013 with 28 percent of respondents saying they were ‘very concerned’ compared to 26 percent in 2012. Overall, 65 percent of respondents this year felt this issue was of concern.

This survey of 1,013 investors, 703 of whom were not retired, was conducted online by independent research firm Mathew Greenwald & Associates as a part of the John Hancock Investor Sentiment Index for Signator Investors Inc. Respondents were required to participate in their household’s financial decision-making process, have a household income of at least $75,000, and assets of $100,000.
