Is it Permitted to Buy Stocks Abroad?

Hello and blessings

It is permitted to buy shares in companies abroad, and one may buy any stock, except for that of a business involved in forbidden foods [marketing all non-kosher meat, etc.], which it is very proper to avoid.

Likewise, if it is known with certainty that the business is Jewish-owned, and the owners do not keep Shabbat and are not signed on a heter iska - then it is forbidden. [Usually one does not know, and then it is permitted, since most businesses abroad belong to non-Jews].

Success,
