i guess some challenges ahead would be the volatility with the china market. This is due to the quick rise in Chinese stocks following the fiscal stimulus announced during China's golden week. but due to the lack of more concrete stimulus, local corproate investors are also not fully convinced it seems, and sentiment is dying down. there might be possibly more volatility ahead for this market due to the greater interest in Chinese stocks. the challenge for traders would be knowing which direction to take. for long term investors, the challenge would be whether China policies do work in the long run.
