While 88% of mutual fund companies that Corporate Insight tracks offer materials on market volatility, only 40% organize this content into centralized outlets. This, Corporate Insight said, is "a key factor in determining firms' effectiveness in communicating with clients and prospects during ongoing market instability."

The market research firm gave high marks to Fidelity, T. Rowe Price and Franklin Templeton for displaying market volatility materials, including streaming video commentary, in well-organized resource centers on their homepages. Fidelity augments this with actionable investment advice and Franklin, T. Rowe, Vanguard and Legg Mason also include prominently displayed letters from their CEOs. Franklin's CEO letter was the most visible, while Vanguard is featuring detailed analysis from an array of high-ranking officials.
