HONG KONG — Under pressure from investors, Samsung Electronics said on Tuesday it might restructure its vast operations as a way to unlock shareholder value.

The family-controlled South Korean electronics giant said it would consider creating a holding company and listing its operations on international exchanges. Samsung will begin a review of its options that will take at least six months, it said.

The review comes after an American hedge fund, Elliott Management, called for the company to take steps to bolster its share price. Those steps included creating a holding company and a listing on an American exchange by one of its arms.

A Samsung move to restructure could ease some of those concerns, according to Sanford C. Bernstein & Company, a research and brokerage firm.
