Stocks have finally shown that they can sell off again, and the Dow was indicated down another 100 points and the S&P 500 down another 11 points on Wednesday. While some of this is around skepticism about tax reform, the reality is that the market simply needs a breather after strong earnings and strong year-to-date gains. Investors should also consider that the trend that has continued to prevail is that investors have bought every major sell-off for more than five years now. Investors are also looking for new investing and trading ideas to generate gains and income ahead.

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 for our readers. Some of these analyst reports and research notes cover stocks to buy. Other reports cover stocks to sell or to avoid.

Additional color and commentary has been added on most of these daily analyst calls. Consensus analyst price target data and valuation metrics are from the Thomson Reuters sell-side research service.
