Rex Tillerson's Personal Portfolio Includes Stakes In Exxon, Oil Rivals And Apple

Holdings In Energy

Naturally, the majority of Tillerson's holdings is in Exxon's stock, but he also holds shares in the company's biggest rivals, including Royal Dutch Shell plc (ADR) RDS RDS, Total SA (ADR) TOT and Chevron Corporation CVX.

Absent from his portfolio of oil stocks is BP plc (ADR) BP, although this may be expected since Tillerson openly criticized the oil company after the 2010 Deepwater Horizon incident in the Gulf of Mexico.

Tillerson's other energy-related companies included in his portfolio are the oil refiner Phillips 66 PSX, the oil services provider Schlumberger Limited. SLB, China-based Sinopec and the conglomerate giant General Electric Company GE.

Beyond Energy

Outside of the energy sector, Tillerson's biggest holding is Apple Inc. AAPL. He also holds municipal bonds from relatively unknown towns in Texas such as Bastrop and Grapevine.

According to some experts, Tillerson's portfolio is nothing out of the ordinary and shouldn't be of concern to investors.

"If you are CEO of a large company, it is hard to hold a large investment portfolio without holding some suppliers or customers," Erik Gordon of the University of Michigan's Ross School of Business told Bloomberg. "You disclose the holdings to the board of directors and divest anything the board thinks is inappropriate."
