Subject: Re: Buffett’s Japanese investment
I specifically keep the shares in terms of foreign currencies, not to make incremental profit on the shares (in theory, there shouldn't be any once their value is translated into greenbacks), but rather to have a diversified currency holding in case the USD suffers some catastrophic trauma not reflected in other currencies.

En anglais, por favor?

Is this like buying stocks on foreign stock exchanges using interactive brokers or a similar brokerage to convert your US dollars into that country's currency?
