Stocks were indicated to open higher on Thursday after small gains on Wednesday, and all major equity indexes remain at or close to all-time highs. The dominating trend of this more than eight year bull market is that investors keep managing to find new reasons to buy stocks after every market sell-off. Those same investors are also on the hunt for new investing and trading ideas with their capital.

24/7 Wall St. reviews dozens of analyst research reports each day. Our goal is to find new investing and trading ideas for our readers. Some of the top analyst reports cover stocks to buy. Other calls cover stocks to sell or to avoid.

The consensus analyst price target data and valuation metrics are from the Thomson Reuters sell-side research service. Additional color and commentary has been added on most of these daily analyst calls.
