NEW INFORMATION FOR INVESTORS

Beginning Sunday, an expanded weekend financial-markets roundup and revised stock listings will be published in The Times Sunday Business Section. These are several in a series of planned enhancements in investor information.

The new roundup will cover major stock indexes, commodities and mortgage guides, and also will include a summary of current interest rates, new state and regional stock indexes and data on foreign currencies and stock markets’ performance.

The Times’ Sunday stock listings will add four-week and year-to-date performance data for every listed issue.
