Curious about higher dividend stocks?

I know this may seem silly to ask and I know that this is a steady growth, accumulation type dividend subreddit. But, what sort of issues or what would be wrong with say investing into certain companies such as the ones below for short term gains due to their dividend %? -MKZR 51% div yield -OXLC 36.59% div yield -FAT 36.18% div yield Etc etc This wouldn’t be money that I’m worried about losing or counting pennies, this is just extra funds I’d be willing to just throw into each of these to catch those supposed big yields.
