A survey of mutual fund shareholders found a link between customer service and consumer satisfaction with investment products, the research organization Phoenix-Hecht Gallup said.

The North Carolina-based company found "an extremely high correlation between investors' perceptions of being valued and their satisfaction with specific service components."

The poll asked customers to evaluate the qualify of information provided by account managers, the accessibility of customer support, the promptness of response to inquiries, and the quality of advice.

The degree of satisfaction with these components translates into stronger or weaker sales of mutual funds, according to the Phoenix-Hecht study.

It also found that the average mutual fund investor has more than $40,000 in stock and bond funds.
