Stocks were getting hammered on Tuesday morning on the heels of disappointing earnings from some key Dow Jones industrials stocks. This is after Monday’s early gains failed to hold by the close. Investors have seen lower upside after buying immediately after the big market pullbacks in 2018 than in prior years, and now the major bank stocks are already seeming to reflect their own bear market.

The investing community needs to consider how to position their investments for the rest of the year and into 2019.

24/7 Wall St. reviews dozens of analyst research reports each day of the week to find new ideas for investors and traders alike. Some analyst reports cover stocks to buy, but some 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 Tuesday, October 23, 2018.
