Apple, Inc. (AAPL) is one of the largest companies in the United States and the first to achieve a market valuation of $1 trillion on Aug. 2, 2018. Although Apple was able to maintain that historic market capitalization from August to November of 2018, the tech giant has since shed roughly $130 billion from its all-time high due to slowing iPhone sales. Apple announced its Q4 2018 earnings on Nov. 1, 2018. The global tech giant reported $62.9 billion in revenues this quarter, nearly a 20% increase from $52.6 billion over the same period last year.

On Dec. 13, 2018, Apple announced plans to build a $1 billion headquarters in Austin, Texas. The 133-acre campus is expected to bring as many as 15,000 additional engineering, sales, and customer support jobs to Austin, making Apple the largest private employer in the city. Apple's domestic and international expansion has made it one of the most popular stocks on the market today, with an average trading volume of close to 21 million shares daily.

For that reason, it shouldn't surprise that many current and former Apple executives have taken the opportunity to amass sizable positions in the company. In this article, we take a closer look at the top five individual shareholders of Apple, Inc. as of Dec. 13, 2018.
