stock NYSEAMERICAN

Where are you seeing this?
It's actually bad data. And this can occur depending on the type of corporate action that occurred.
First - MYND has never paid a dividend.
What's happening is that the bad data is being used to calculate a dividend yield for MYND in the way that u/StatisticalMan and u/sirzoop mentioned.
But it's a bit more complicated.
The current MYND company is formed through an M&A with Gravitas Education Holdings. This M&A resulted in a one-time special dividend to GEHI shareholders when GEHI was acquired by NetDragon. The newly merged company was then renamed to MYND.
The special dividend from the M&A corporate action isn't being correctly processed by all data aggregators/providers so you may sometimes see this dividend and the incorrect yield for MYND.
