Zacks Bull and Bear of the Day Highlights: Norfolk Southern, Atmel Corp., Amdocs and Caterpillar

Business Wire, Nov 21, 2007

The performance of the Zacks Rank portfolios shown above for annual and year-to-date periods are the linked monthly total returns (price changes dividends) of equal weighted hypothetical portfolios, consisting of those stocks with the indicated Zacks Rank, assuming monthly rebalancing and zero transaction costs.

These are not the returns of actual portfolios. The hypothetical portfolios were created at the beginning of each month from Jan 1988 forward based on the values of the Zacks Rank available to Zacks' clients before the beginning of each month. The portfolios created monthly from 1988 through September 2006 exclude ADRS and are comprised of stocks that have the indicated Zacks Rank and were covered by at least two analysts at the time of the stocks inclusion in the portfolio. Starting in October 2006 and going forward, the portfolios are comprised of all stocks with the indicated Zacks Rank and do not exclude ADRs, which is more reflective of the list of stocks that customers will find on the Zacks web sites. 2007 returns are for the period of Jan 1 - Jun 30, 2007. These performance numbers have been audited from 1995 through 2003 by Autschuler Melovan, a division of American Express Financial.
