Millionaires with financial advisors have lost less money during the financial crisis than those who don’t work with an advisor, according to a new study by Fidelity Investments.

The study surveyed 1,000 households with at least $1 million in investable assets in February 2009. It found that millionaires who work with an advisor lost an average of 4% of their assets during 2008. Meanwhile, millionaires who didn’t work with an advisor saw an average decline of 18% of their assets.

And these millionaire clients credited their advisors’ work. Seventy-six percent of respondents who use an advisor acknowledged that their advisors helped to limit their losses. Also, 85% of those clients stayed with their advisors during the crisis, while one in ten stopped working with an advisor altogether.

Unsurprisingly, millionaire clients said they wanted to communicate more often with their advisors during this time. Twenty-nine percent of respondents with advisors said they preferred to communicate with them at least once a week, up from 20% last year.

“With investors’ appetite for more support, broker/dealers and advisors may be challenged to find the time and resources,” said Gail Graham, executive vice president of Fidelity Investments, in a statement. “They will need to look for ways to enhance operational efficiencies to devote more time to keeping in touch with clients.”
