Stocks were weak on Friday morning ahead of the unemployment and payrolls report, due to an expanded potential of $100 billion more in tariffs against China. The market has been swinging up and down, the bull market is now over nine years old, and the trend of buying pullbacks has become much more vulnerable to sellers and volatility trades. All this is making it harder for investors to decide how they want their assets positioned for the rest of 2018 and beyond.

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.
