Stock Challenge!!!

There are currently 3 stock challenges from:

1. OCBC
2. Citibank
3. Poems

All claim to let people test out their "investing" skills and pit to win attractive prizes.

But... investing? How can a mere 2 months show your investing skills? Investing is seeing companies as businesses. How can 2 months show that you picked a profitable company? How can companies show how profitable and how much they can grow within a span of 2 months?

They should call it a pitting of trading and speculating skills instead.
