Stocks are coming off of a miserable week, but the futures were marginally positive on Monday morning. Investors have seen less upside from buying immediately after the big market sell-offs than in prior years, and now they have to consider how they want their investments and assets positioned for 2019.

24/7 Wall St. reviews dozens of analyst research reports each day to find new ideas for investors and traders alike. Some of these analyst reports cover stocks to buy, while others cover stocks to sell or to avoid.

Additional commentary has been added on most of the daily analyst reports, along with trading history. The consensus analyst price targets and other valuation metrics are from the Thomson Reuters sell-side research service.

These are the top analyst upgrades, downgrades and initiations seen on Monday, December 10, 2018.
