Have you heard of FootballIndex? It’s UK based website which allows people to trade ‘shares’ in professional soccer players.
So let’s say you pick a 17-year old player for $1 and he bursts onto the scene and becomes the next Messi or Ronaldo his share value will increase to $20 and that’s when you sell him and cash in your chips.
Davey Day Trader should set up a trading platform like this but for American sports. NBA, NFL and NHL.
Own the platform!
