Top Analyst Upgrades and Downgrades: Abengoa Yield, CSC, Groupon, 3M, Vertex, Williams, Xerox and More

Stocks were lower again on Tuesday ahead of the unofficial launch of earnings season and after the DJIA 17,000 milestone was hit for the first time ever last week. Now many investors are trying to decide if this is becoming a stock picker’s market or yet another leg up in a bull market that is now over five years old. 24/7 Wall St. reviews dozens of analyst research reports each morning of the week for new ideas for our readers. Some of the analyst research reports cover stocks to buy, and some of them cover stocks to sell or to avoid.
