If a Canadian investor buys one million dollars worth of stock in an American commpany, how does this transaction appear in the national income accounts of the United States?

A.the balance of trade rises as we export $1 million of stock

B the balance trade falls as we import Canadian investment

C.Net capital outflow rises by 1$ million

D.Net capital outflow falls by 1$ million

答案是D。答案解释说Trade in financial assets is counted in net foregin investment.Since a foreigner is buying American assets, this appears as a decrease in U.S. net capital outflow.

我想问下Trade in financial assets is counted in net foregin investment.这个是什么意思阿？

这题怎么解释？

能告诉我吗？谢谢啦
