Some of these companies are directly impacted by pandemic, such as PM, UVV, MO, & OKE. The three first companies there are in the tobacco industry, while the last in is the energy sector.
Both of these industries have been heavily impacted by the pandemic, especially energy.
However many of them have paid dividends for a long time, and even growing dividends, which proves that no matter what crisis they are still able to provide investors with good returns.
But a high yield does not necessarily mean a good buy, nor does a share price drop mean itās a good buy other. When the share price drops, the dividend yield rises, so itās not a good thing.
I do own many of those you have listed here, and quite frankly I believe they are undervalued in the long run. But itās gonna take a while for oil to recover from this, and as an investor you need to be aware of that. Short term there are better options out there for those who donāt like high risk, such as PEP, KO, WMT, etc.
But if you believe in tobacco, oil&gas, real estate & finance to recover from this, then I think these are a good buy, but not without risk. I liked the pie, and like I said, I have most of them myself, and there are worrying things with some of them.
