How to Regularly Access Picks from the Zacks Rank Discovery for Free: http://at.zacks.com/?id=88

Underlying the four free stock picks is a simple truth that first appeared in a Financial Analysts Journal article published in 1979. Leonard Zacks, a Ph.D. in Mathematics from M.I.T. found that "earnings estimate revisions are the most powerful force impacting stock prices." Zacks #1 Rank is awarded to a stock when analysts sharply upgrade their estimates of what the company will earn.
