The correlations were computed using the weekly returns from the period 1973-1982 Source: C.Eun and B. Resnick, "Estimating the Correlation Structure of International Share Prices." Journal of Finance, December 1984. p. 1314. Exhibit 15.2 avides historical data on the international correlation structure. Specificat de table provides the average pairwise correlations of individual stock returns wie ein country in the diagonal entries, and the average pairwise correla- tions oi surns between countries in the off-diagonal entries. The correlations are in terms of US dollars and computed using the weekly return data from the period 1973-1982. As can be seen from the table, the average intracountry correlation is 0.653 for Germany, 0.416 for Japan, 0.698 for the United Kingdom, and 0.439 for the United States. In contrast, the average intercountry correlation of the United States is 0.170 with Germany, 0.137 with Japan, and 0.279 with the United Kingdom. The average correlation of the United Kingdom, on the other hand, is 0.299 with Germany and 0.209 with Japan. Clearly, stock returns tend to be much less correlated between countries than within a country. The international correlation structure documented in Exhibit 15.2 suggests that international diversification can sharply reduce risk. According to Solnik (1974), that is indeed the case. Exhibit 15.3, adopted from the Solnik study, first shows that as the portfolio holds more and more stocks, the risk of the portfolio steadily declines, and eventually converges to the systematic (or nondiversifiable) risk.
