The world's most valuable company could become a lot more valuable if history is any indication.
With its recent run, Apple's total market capitalization is now above $750 billion. And while that figure boggles some traders' minds, a closer look at the singular mega-cap leaders of the S&P 500 throughout the last 30 years suggests that Apple's market value could balloon to more than $1 trillion.
According to data from Standard & Poor's senior index analyst, Howard Silverblatt, Apple represents about 4.05 percent of the S&P 500's total value. Even though that constitutes a relatively large portion of the market, no less than five other companies have achieved higher percentages of the S&P 500's total market cap since 1980, including IBM, AT&T, Exxon Mobil, Microsoft and General Electric.
