Answer:
Trade balance
Step-by-step explanation:
A positive trade balance will result in currency appreciation because more goods are exported than imported, which means that there is a net inflow of the home country's currency, increasing its value against foreign currency.
This can lead first to more foreign direct investment because a trade balance is a sign of a strong economy, however, in the long run there can be a radical change in the business cycle: the appreciated currency will make the home country's goods more expensive, reducing the demand for them abroad, in turn decreasing exports, turning the trade balance into negative numbers, and causing a net ouflow of foreign direct invesment due to the weaker economy, and the capital losses because of the currency depreciation.
