Stocks were indicated to open higher on Wednesday after Tuesday’s strong sell-off. The indexes still remain close to all-time highs, and the one trend that has prevailed for more than five years is that investors have managed to keep finding new reasons to buy stocks after every sell-off. Many of those investors are also looking for new investing and trading ideas to generate gains and income.

24/7 Wall St. reviews dozens of analyst research reports each day of the week in an effort to find new investing and trading ideas for our readers. Some of these top analyst reports cover stocks to buy. Other analyst calls are reiterations of ratings, and some even 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 Wednesday, September 6, 2017.
