Americans are growing increasingly worried about having enough money for retirement, but that fear is turning to paralysis, as fewer investors make changes to stem future losses, a new study found.

The AXA Equitable survey found that 65% of Americans were worried about meeting everyday expenses should they lose their job, up from 54% in a similar study last year.

"Our research showed that paying bills was a middle-of-the-pack concern last April," said Christopher "Kip" Condron, chairman and CEO of AXA Equitable. "The fact that it is now a top priority underscores how the yearlong market volatility has shaken Americans' sense of security about their immediate financial future, most notably as a result of job instability."

Securing guaranteed income for life remains the top priority for 69% of Americans, but half the survey respondents said they have done nothing to change their financial situation, the survey found.

"The fact that people are still concerned about the health of their retirement during the market volatility we are experiencing makes it clear that they still understand the importance of preparing for their financial future," Condron said. "What is alarming, however, is that so many are still not taking the steps needed to achieve these goals."
