One example of opportunity cost is in the evaluation of "foreign" (to the US) buyers and their allocation of cash assets in real estate or other types of investment vehicles. With the recent downturn (circa June/July 2015) of the Chinese stock market, more and more Chinese investors from Hong Kong and Taiwan are turning to the United States as an alternative vessel for their investment dollars; the opportunity cost of leaving their money in the Chinese stock market or Chinese real estate market is too high relative to yields available in the US real estate market.
