Stocks were indicated lower on Friday after taking a breather on Thursday. The market indexes may have recently hit all-time highs after a strong earnings season, but investors have seen less upside from the “buy the sell-offs” mentality that worked several years. Those same 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. The goal is to find new investing and trading ideas for our readers. Some analyst reports cover stocks to buy, but some 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.

These are the top analyst upgrades, downgrades and initiations seen on Friday, August 31, 2018.
