Since the beginning of the year, the MSCI Emerging Markets has advanced by 25%, and is now flirting with its August 2014 level. This follows two disastrous years during which the index lost up to 30% of its value. Even though it has been amplified by the weak dollar, this performance illustrates how emerging markets have come alive again over the past three months. In local currency, Brazil and Turkey, the most dynamic of them, have risen by 7-12%, while the vast majority of the others—Colombia, China, South Africa, Mexico, Saudi Arabia and Russia—have seen 4-8% rises. In other words, emerging markets have been more or less spared the upheavals affecting the developed world since the middle of the summer. This outperformance is often attributed to the beneficial effects of the decline in the dollar, but the real causes seem more complex. Let’s take a look.
