What is disinvestment?

Disinvestment refers to the use of a concerted economic boycott, with specific emphasis on liquidating stock, to pressure a government towards policy or regime change. The term was first used in the 1980s, most commonly in the United States, to refer to the use of a concerted economic boycott designed to pressure the government of South Africa into abolishing its policy of apartheid. The term has also been applied to actions targeting Northern Ireland, Myanmar, and Israel. from http://www.wikipedia.org greetings. : )
