The 20 Most Valuable Companies In America

Apple (AAPL) and Alphabet (GOOG) have jockeyed for the lead as America's most valuable company, each with a market cap of about $550 billion. One tech giant vs. another. A look at the top 20 American public corporations reveals several other close comparisons

One note is that the top five positions on the market cap table are tech companies, and have left large energy companies behind. After Apple and Alphabet are Microsoft (MSFT) at $435 billion, Facebook (FB) at $364 billion, and Amazon (AMZN) at $360 billion.

All five companies are trying to play in at least one of the others' backyards. Microsoft, Amazon, and Google are among the cloud computing leaders. Amazon and Apple continue to fight each other for dominance in the streaming media market. Microsoft, Apple, and Alphabet are all in the mobile OS market. The only company on the list without a significant challenger is Facebook, one of the reasons its market cap is so high.

Walmart (WMT) is on the list at $217 billion. Investors in rival Amazon and Walmart cannot help noting how far bricks and mortars have fallen behind e-commerce. Walmart is trying to catch up, piecemeal, most recently with its $3 billion buyout of Jet.com.

Two major banks are on the list, with market caps fairly close to one another. JPMorgan (JPM) at $240 billion and Wells Fargo (WFC) at $245 billion.
