Stocks sold off handily on Tuesday as the 3% mark on the 10-year Treasury yield was challenged, but stocks were trying to stage a small rally on Wednesday morning. Some investors have reconsidered what the nine-year bull market may bring in 2018 and beyond. It has become clear that the multiyear trend of buying pullbacks is now more vulnerable to sellers, volatility and each major news headline. Many investors are finding it harder to decide how they want their assets positioned for the longer term.

24/7 Wall St. reviews dozens of analyst research reports each day of the week. Our goal is to find new ideas for investors and traders alike. 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 reports. The consensus analyst price targets and other valuation metrics are from the Thomson Reuters sell-side research service.
