Stocks took a breather on Thursday on a slower news day after gains seen this week. The market indexes have hit all-time highs as trade fears ease and as earnings season was very strong. Investors have by and large seen lower rewards for buying the dips in 2018 than in prior years. Investors also are trying to decide how they want their investments positioned for the rest of 2018.

24/7 Wall St. reviews dozens of analyst research reports each day of the week in an effort to uncover new investing and trading ideas for our readers. Some of the daily analyst reports cover stocks to buy, and some reports cover stocks to sell or to avoid.

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