Stocks were mixed on Friday, but the almost nine-year raging bull market has hit new highs this week. The Dow Jones Industrial Average went over 26,100 and had the fastest 1,000 point move on record in 2018, and the trend of buying stocks on any dips remains the winning move. Investors are now deciding how to position their portfolios for 2018 and beyond, and they are looking for new investment 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 investors and traders alike. Some of the analyst reports and research reports cover stocks to buy. Others cover stocks to sell or to avoid.

Additional color and commentary has been added on most of these daily analyst calls. Consensus analyst price targets mentioned and other valuation metrics are from the Thomson Reuters sell-side research service.
