Stocks were indicated higher on Tuesday, although on a much more muted tune than the 320-point Dow Jones industrials gain and the 24-point gain on the S&P 500 seen on Monday. The prior trend of buying every dip and sell-off has been less reliable during most of 2018 than in prior years. Many investors now are considering how they want their investments positioned ahead of the midterm elections and also for the longer term into 2019 and beyond.

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

Additional color and commentary have 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.
