Mainly because an under reported consequence of the US weak $ policy is that it squeezes margins in EM. Most EM firms are operating on margins far narrower than developed nation firms, they are also having to content with very high commodity prices. In addition I think the US consumer is on its last legs as far as buying power goes as indicated by the recent rise in consumer debt. Consumers are unable to drawn on their home equity and are now using high interest CC to mantain their lifestyle, resets are likely to add to this trend. The fall out from housing and credit problems are going to be felt in the next three-six months and they will slow the GDP growth significantly more than people are expecting.
Why The EMM, because as we drift in to recession I feel that is where the highest RR lies, not in US equites which will be propped up by the weak $. US and Multi national companies earnings will not be as severely tarnished due to the currency effect that they will enjoy.
Why now, this bullish euphoria manufactured on nothing more than an opening of the credit spigot is a good opportunity to add to the position.
The risk is that I am early here hence the tight stop, though it may prove to be too tight.
