Stocks have been swinging up and down for several days now, but the major indices were indicated to open up on Thursday. The bull market may now be over nine years old, but it has become more obvious that the trend of buying pullbacks is now much more vulnerable to sellers, volatility and each major news headline. This makes it more difficult for investors to decide how they want their assets positioned for the rest of 2018 and beyond.

24/7 Wall St. reviews dozens of analyst research reports each day of the week. Our goal is to find new ideas for investors and traders alike. Some analyst reports cover stocks to buy and some 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.
