Stocks were indicated higher on Thursday after regulators watered down the notion that China would stop buying U.S. debt. The bull market is now less than two months shy of nine years old, and the trend that keeps on working is to buy pullbacks. Now investors are looking at how to position themselves for 2018 and beyond with tax reform and accelerated earnings and GDP growth driving the interest. Those same investors are also looking for new ideas.

24/7 Wall St. reviews dozens of analyst research reports each day of the week to find new investing and trading ideas for investors and traders alike. Some of the daily analyst reports and research reports cover stocks to buy, and some cover stocks to sell or to avoid.

Additional color and commentary have 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.

These were the top analyst upgrades, downgrades and other research calls from Thursday, January 10, 2018.
