Blue Chips, Red Chips… Large Cap, Mid Cap, Small Cap- most investors understand there is a range of different sizes of public companies. Today, the largest companies have stock market capitalizations (the total number of shares outstanding multiplied by the stock price) approaching one trillion dollars, while the smaller stocks in the public realm sport capitalizations less than $50 million. The largest companies are extremely well known, widely held by investors, and heavily researched on Wall Street.
