Mega-cap
Extracted from the Wikipedia article Megacap stock.
In business and investing, a megacap stock (also mega-cap or mega cap) is a stock whose market capitalization (market cap) is among the very largest. These are stocks of the largest publicly traded companies in the world. The market capitalization of a stock is the total value of the shares outstanding, calculated as (shares outstanding x share price). Stocks with large market caps, but smaller than megacaps, instead fall within the large-cap segment of the stock market.
