The chart of the week illustrates the difference in valuation between U.S. and international stocks. Typically, U.S. stocks are considered safer and more stable, which is why they usually trade at a premium compared to international stocks. However, the chart reveals that international stocks are currently trading at a discount of two standard deviations below their historic average compared to U.S. stocks. Although this may not be a definitive reason to invest in international stocks, it may be worth a second look.
