CAG

I've followed CAG for 20 years. Never bought it. Originally I figured that the evil empire would never lose and it would be a good investment. It has so vastly underperformed the SP500 it's not even funny.

CAG may or may not be a good buy. It would take a lot more research to understand.
For all I know looking at the charts they went through a patch of massive acquisitions and are now poised to dominate their segment. Or they hit major obstacle in their core business and are about to collapse further. Or any number of other possibilities.
But generally speaking div yield is inversely correlated to share price. High yields often mean the price has fallen.
The main baskets that can have higher yields and still be considered conservative buys are pharma, tobacco, reit's and mlp's but you should always research any stock before buying.
If you don't know how to do the research or don't want to, use 3rd party options that are not also trading platforms. Morningstar, Koyfin, Seeking Alpha etc.

Pretty sure CAG just halved their dividend
