Stocks were indicated to open higher on Tuesday. U.S. equity indexes remain very close to their all-time highs, while most international markets are not close to their highs. One issue that has to be considered is that investors have seen less upside from buying on market pullbacks than in prior years. Investors also need to consider how they want to have their investments positioned for the rest of 2018.

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 reports cover stocks to buy, but some of the analyst reports cover stocks to sell or stocks 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.
