Stocks got hammered on Wednesday after growing concerns that all or most of the pro-business efforts driving the market will be delayed or derailed. Major equity indexes were indicated lower again on Thursday, with the Dow indicated down 65 points and the S&P 500 indicated down five points. That may sound like another very negative trading day, but the Dow was down 372 points and the S&P 500 was down almost 44 points on Wednesday.

Investors need to consider that the markets are still very close to all-time highs. And even with the bull market more than eight years old, those same investors need to consider that investors have found myriad reasons to buy every single major sell-off for more than five years now. Investors and traders alike are also looking for new trading and investing ideas.

24/7 Wall St. reviews dozens of analyst research reports each day of the week. The goal is to find new investing and trading ideas for our readers. Some of these analyst reports cover stocks to buy and others cover stocks to sell or to avoid.
