At Tier 1 Investments, I seek out and invest in elite businesses. These include companies with the most valuable brands, best management, superior products and services, and strongest competitive advantages.

As much as I love an underdog, Nike (NYSE:NKE) is still the king of the roost -- and for a reason. While I've picked Under Armour (NYSE:UA) as a Tier 1 investment, that doesn't mean that Nike's broken. In fact, you may do well buying both.
