Market Capitalization 

MCap ... Right-size me (Large, Medium & Small) … with Fries?

Move away from trying to pick stocks or stocks within sectors. Instead, trade the options on the mini versions of the Major Indexes across the different market cap categories, as part of managing concentration risk in your portfolio.
