Stocks were indicated to open higher yet again on Tuesday for all-time highs on the Dow and S&P 500. The one theme that has persisted through all the caution and worrying is that investors keep finding new reasons to buy the major indexes after each and every single sell-off. The eight-year-old bull market is still charging. Investors are also searching for new investing and trading ideas.

24/7 Wall St. reviews dozens of analyst research reports each day of the week to find new investing and trading ideas for our readers. Some analyst reports cover stocks to buy and some 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.
