Top Analyst Upgrades and Downgrades: ADM, BlackRock, DexCom, Mallinckrodt, McDonald's, Philip Morris, Redfin and More

Stocks were indicated to open lower on Thursday, but the indexes remains very close to all-time highs. The trend that has prevailed during this eight-year bull market is that investors keep finding new reasons to buy stocks after every market sell-off. Those same investors also are looking for new investing and trading ideas to generate gains and income.

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

Additional color and commentary has been added on some of these daily analyst calls. The consensus analyst price target data are from the Thomson Reuters sell-side research service.

These were the top analyst upgrades, downgrades and other research calls from Thursday, September 28, 2017.
