The Dow may have crossed 22,000 for the first time ever, but Thursday’s opening bell was one in which stocks were simply looking for direction. Even with the bull market being eight years old now, the common theme that has persisted and been victorious through all the caution and worrying is that investors keep finding new reasons to buy stocks after every sell-off. Those same investors are also searching for new investing and trading ideas.

24/7 Wall St. reviews dozens of analyst research reports each day of the week to find new investing and trading ideas for our readers. 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 calls. Consensus analyst price target data are from the Thomson Reuters sell-side research service.

These were the top analyst upgrades, downgrades and other research calls from Thursday, August 3, 2017.
