In the battle for the first company to reach and sustain $1 trillion in stock market value, don\u2019t count out a come-from-behind victory. Apple Inc. has had a lock on its spot as the world\u2019s most valuable public company by stock value for several years, and we\u2019ve been waiting for it to crest the $1 trillion market cap milestone. The company inched within $50 billion of that mark in early June before its share price retreated a bit. Apple\u2019s trek to $1 trillion has been closely chronicled by news outlets, including this one, and it\u2019s a good bet there are articles and essays prepped for what seems like an inevitable moment for Apple. Amazon, though, is coming up fast. At the beginning of this year, Apple\u2019s stock market value was 50 percent bigger than Amazon\u2019s. Now the gap is about 10 percent. The spread between the two companies was about $85 billion as of Friday\u2019s U.S. market close. That is a big but not insurmountable gap if Amazon keeps up its torrid stock gains. In 2018 alone, the value of Amazon\u2019s shares has climbed $260 billion. Yes, Amazon has added the equivalent of Walmart\u2019s total market cap in just six months. Amazon\u2019s position among the stock market\u2019s elite would have been tough to predict a few years ago. In the summer of 2011, when Apple (briefly) topped Exxon Mobil for the first time as the most valuable company in the world by market cap, Amazon was barely in the top 50. Amazon only found its groove starting in 2015, and since then it has been on a tear as investors started to believe in Amazon\u2019s strategy to spend like crazy to try to become ingrained into every aspect of people\u2019s lives \u2014 in the home, at work, at play, during meal times, in sickness and in health. As Amazon\u2019s ambitions have increased with each passing day, investors have grown more excited about the size of the company\u2019s financial opportunity. The company\u2019s two main business lines, retailing and information technology, represent $20 trillion and $2 trillion of annual spending, respectively. Amazon captures a tiny share of each category, and if it manages to grab bigger chunks, then it is sitting on a gold mine. And that\u2019s before addressing Amazon\u2019s potential to crack additional lucrative areas such as health care and advertising. But the Wall Street analysts who track Apple, Amazon and other technology superpowers aren\u2019t necessarily predicting any of them will hit $1 trillion soon. Using their average 12-month stock price targets for the largest U.S. technology companies, analysts peg Apple\u2019s target market value at about $974 billion, with Amazon and Microsoft behind it. A lot can go wrong for Amazon in the march to $1 trillion. Investors are willing to pay a higher price for each dollar of Amazon\u2019s expected future profits than they are for any other technology giant. Amazon is trading is trading at more than 46 times its cash from operations over the last 12 months, according to Bloomberg data. Apple is valued at about 11 times on the same basis. If Amazon stumbles or if there\u2019s a return of doubts about Amazon\u2019s business strategy, its high valuation could become an anchor that drags down its market value. The $1 trillion market cap is a vanity milestone. It doesn\u2019t truly matter, except in bragging rights. But the fact that Amazon is even in the conversation shows how much has changed quickly in investors\u2019 faith in Amazon\u2019s strategy and its ability to worm its way into more nooks of commerce.
