KOSDAQ market caps relative to revenue are dizzying

‌Of course, you shouldn't compare them to KOSPI blue chips, but
they are still in the top tier...
Companies with hundreds of billions in revenue having market caps of 15 trillion or 9 trillion.
It's probably 100% due to the Samsung effect, but Rainbow has tens of billions in revenue with an 8 trillion market cap.
The top tier is all like this.
Personally, I feel like if you pick the wrong one, you could truly die.
