Stocks managed to sell off on Monday after a whole week of hitting higher all-time highs. The Dow Jones Industrial Average was indicated to open over 100 points higher on Tuesday all over again, and the index cut through 23,000 like it wasn’t even there. The trend that has prevailed for more than five years now is that investors keep finding new reasons to buy stocks after every major sell-off. Those same investors also are hunting for new investing and trading ideas to generate gains and income ahead.

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 the top analyst reports cover stocks to buy, while other calls cover stocks to sell or to avoid.

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.
