Fidelity Muzzles Portfolio Managers

Fidelity Investment Co., the nation’s biggest mutual fund company, has barred its portfolio managers from publicly discussing individual securities after the head of its largest fund was sued for talking about stocks he was selling.

Fidelity said Tuesday that it told its 70 fund managers last month to curb such comments to news reporters.

The company also began including a statement in reports to shareholders that any discussion about securities pertains to performance earlier in the period and is not an opinion of future events.
