Stocks were lower on Monday, but perhaps not as bad as many might have worried about considering the government shutdown. What investors have to consider is that prior to the pullback, the Dow Jones Industrial Average went over 26,100 and had the fastest 1,000-point move on record of just eight trading days. Investors also have to consider that buying stocks on any dips has been the winning move for about six years now. Now it’s time to decide how to position portfolios for 2018 and beyond.

24/7 Wall St. reviews dozens of analyst research reports each day of the week. The goal is to find new investing and trading ideas for investors and traders alike. Some 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.

24/7 Wall St. has also identified 10 top technology giants that analysts have grown more bullish for strong earnings and guidance ahead of their formal earnings reports in the next couple of weeks.
