24/7 Wall St.

Stocks were looking steadily lower on Thursday ahead of the three-day Easter weekend. The S&P 500 and Dow Jones Industrial Average both went positive for 2016 last week, but now the five weeks of consecutive gains look challenged. The issue for investors and traders alike now is whether they should be selling back into rallies or they should keep buying the dips.

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

These are top analyst upgrades, downgrades and initiations seen Thursday morning:
