Confused about the contest description

The Description of the contest says: "The diversified long only portfolio must be equally weighted, fully invested and must contain 50 stocks at any moment of time."

Does it mean that:

  1. we could not short stocks
  2. the stocks we invest in must be equally weighted
  3. I am not sure what “must contain 50” means. Does it mean >= 50 or ==50?

Thanks a lot!

There is not much confusion possible here:

  1. long only: you cannot short stocks.
  2. equally weighted means each stock has the same weight.
  3. 50 stocks means 50 stocks.

From 2. and 3. you can deduce that at each rebalancing date, each of the 50 stocks will be 2%; others will all be 0%.
