NEW YORK (TheStreet) -- Some words and concepts in finance are simple and easy enough to guess their meanings: diversification, mutual fund, risk management, price/earnings ratio.
Other financial terms always seem to throw me for a loop. Even though I understand them, I find myself secretly looking up these terms over and over again just to smash the concept into my head.
Thanks @Investopedia, @Nasdaq and @Stox for always being there for my financial definitional needs.
One of those evasive concepts is "market capitalization." I hear the term all the time and I look up a company's market capitalization for every stock I trade, so you know I know what it is. I use the computation and the concept of what market cap means in my stock selection and analysis, but when I try to define it I feel compelled to look it up again.
What is Market Capitalization?
Market Capitalization is the current market value of all of the shares of stock that are outstanding for a publicly traded company.
Not long ago, people spoke of large-cap, mid-cap, and small-cap stocks. I blinked and somewhere along the way we went from these three categories to the six -- mega, large, mid, small, micro, and nano -- shown below.
These capitalization designations come from www.nasdaq.com.
