Stocks have been looking for a base, but futures were down handily despite a strong jobs report from ADP. The culprit for Wednesday’s selling is more retaliatory tariff news out of China, with the Dow Jones industrial average indicated down 2.1% and the S&P 500 indicated down 1.5%.

You have heard over and over that the bull market is now over nine years old, but now the Dow and S&P 500 are challenging their 200-day moving averages for the first time in two years. The trend of buying pullbacks has worked for years, but now the sellers and volatility are more able to win than they have been able to in a long time. This is making it ever 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 of the daily analyst reports cover stocks to buy. Others 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.
