G100 Ranking - S&P 500
Ronald Domingues runs a "G100 Ranking" for the S&P based on participant predictions for the S&P over the next 24 hours. Up to 100 individuals can qualify to participate if they score greater than 35% accuracy in their predictions (currently 33 make the grade). Underperformers are demoted back to a pool, and those from the pool with a greater than 35% accuracy are promoted. Prior to the market open he sends an email out with the results of the poll.
