I have discovered interesting "periodic tables" of returns for select emerging markets during the years between 1993 and 2008. These charts (click on each chart for a larger view) are interesting and illustrate just how volatile and potentially rewarding investments in emerging markets can be.
Country-specific returns can be extremely volatile. For example, the Turkish stock market had some of the highest and lowest yearly returns for several years during the past 15 years. In 1993, Turkey returned of 207.75%, the highest of the tracked emerging markets. In 1994, however, Turkey had the lowest return of the tracked markets, dropping 52.56%.
I found these charts in a .pdf file on the website for Lazard Asset Management. According to the Lazard website, Lazard Asset Management provides investment management and advisory services to institutional clients, financial intermediaries, private clients and investment vehicles around the world.
