Exits are lessons, not failures.
We publish every position we exit, including the ones that lost money. A small loss that teaches the whole club something is a win we get to keep forever.
How the money works
Contributions to Mosaic are donations to the club's shared portfolio, not personal investments: members don't own individual shares and contributions aren't returned. No student handles the money, and nobody has to contribute to participate.
Pitches & voting
Pitch, discuss, and vote.
This is where members do the real work: submit a pitch, read the discussion, and vote on what the club buys and sells. Sign in with your member email to take part.
Want a vote on the next pick?
Every member researches, pitches, and votes. Open to high schoolers 18 and under, anywhere in the world.
