What does it mean when a token has a sustained high vol/market cap percentage?

[Dark Helix]

Just wondering why a token would have a very large percentage for this as the top coins all have low ones.

Example, Aeron (ARN) has had a Vol/MCap that has been in the multiple 100% for the passed few days or so. At its height, it got to over 500% and held. It still currently holding at 300%.

It isn’t on many exchanges but mostly traded on Binance. It has a very low circulating supply of 13m (total 20m).

Just wondering why the market cap stays so low.
