The invention provides index performance alerts by sector. The index alerts are based on price performance measures of each industry, sector, sub-sector, or group (referred to collectively as "sector" herein). Users are able to define limits for the industry, sector, sub-sector, or group categories for alerts on price, volume, intraday range, current closing price relative to the intraday range, price to revenues, price to earnings, price to book value, and price to cash flow. Users have the ability to define at least one area in a hierarchy of industry, sector, sub-sector, or group levels, for setting alerts. Users also can request tickers of individual companies. The invention also provides news alerts for a user selected hierarchy level and/or an individual ticker symbol. Users are alerted when a news story, linked to a user-specified group or ticker, is created. The invention uses a proprietary product/service hierarchy methodology for categorization of companies, wherein the categorization methodology automatically extends the functionality to deliver a plurality of other alert notifications associated with subsidiary classifications, constituent companies' classifications, or to securities instruments. A preferred implementation of communication delivery is standard e-mail as well as XML using push technology. |
