Jupiter Media Metrix has introduced the financial services industry's first index based entirely on online consumer behavior and performance metrics. The Jupiter CORE (Composite Rating of Online
Effectiveness) Index -- designed to help financial services firms assess their competitive strengths and areas of exposure online -- will be published quarterly and is made up of individual scores
relating to unique visitors, usage intensity (time), usage frequency (number of visits per month), customer loyalty or transition (the ability to migrate off-line customers online). BankofAmerica.com,
WellsFargo.com and KeyBank.com lead the Jupiter Banking CORE, while E*Trade Financial Network, TDWaterhouse.com and Sharebuilder.com top the Jupiter Brokerage CORE.
