24/7 Wall St.

Stocks were down on Wednesday and have been volatile for the past couple of weeks. All three major equity indices were indicated higher on Thursday, but by only about 0.1% or 0.2%. The bull market is now over nine years old, and investors are trying to weigh the recent volatility to decide how they want to be positioned for the year ahead and beyond. One trend that has kept working is for investors to buy all the big pullbacks.

24/7 Wall St. reviews dozens of analyst research reports each day of the week to find new ideas for investors and traders alike. Some analyst and research reports cover stocks to buy. Others cover stocks to sell or to avoid.

Additional color and commentary has been added on most of the daily analyst reports. The consensus analyst price targets and other valuation metrics are from the Thomson Reuters sell-side research service.
