A children's book explanation of what's happening:

1. If you are "smart money" you are allowed to take your $1 and leverage it up to $15+

2. You can now buy $15 of stock AND if you promise to short companies, you can short $15 of stock as well

3. In finance language, this means that you are $30 "gross" ($15 of longs + $15 of shorts) but $0 net (+$15 of longs -$15 of shorts). This makes everyone feel good because it feels like you are taking zero risk...but in reality, your $1 is exposed to $30 of risk.

4. Now you go around and tell your friends about both your longs and your shorts and when you do it at a restaurant vs on Reddit, its called an "ideas dinner".

5. You also publish your longs on a quarterly lag via an SEC rule. You don't have to tell anyone about your shorts.

6. Now the less cool people who weren't invited to the ideas dinners, start copying your longs based on your report.

7. You realize that publicizing your shorts is also a good idea so instead of only selling stocks, you also BUY options (puts) which has to be reported.

8. Now everyone can see both your longs and your shorts and if you have a hot hand, you can likely predict that the cool people from the dinner as well as the less cool people monitoring your filings will copy you.

9. But then an outsider notices that the math is way off!
