NEW YORK (TheStreet) -- Global markets have clocked substantial gains during the past one month with India's Nifty being an outperformer. The index gained 8.1%, while Brazil's Bovespa was up 0.6%. This compares to the 5% increase of the S&P 500 and 3.9% rise of the Dow Jones. On the contrary, the Shanghai Composite registered a decline of 2%.
