24/7 Wall St.

Stocks closed higher Tuesday and Monday but were looking for direction on Wednesday morning. All in all, the markets are right at all-time highs, and the 19,000 Dow Jones Industrial Average has a shot at rising to 22,000 if the animal spirits grab hold in 2017. A lot has to go right for that to occur. Still, even with a bull market that is almost eight years old, the appetite is to buy shares on pullbacks. Investors are also looking for new ideas for gains or income.

24/7 Wall St. reviews dozens of analyst reports each day of the week to find new investing and trading ideas for its readers. Some of these analyst research reports cover stocks to buy, and other calls cover stocks to sell or avoid.
