24/7 Wall St.

Stocks were indicated to open lower on Thursday, a day after the Nasdaq regained lost footing when the Dow and S&P 500 turned in mixed results. This bull market is now well over eight years old, but equity investors have proven time after time that they want to and will buy any major pullback or sell-off in stocks. Investors also continue to search for new investing and trading ideas.

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

Consensus analyst price target data are from the Thomson Reuters sell-side research service. Additional color and commentary also has been added on most of the daily analyst calls.
