Five things to think about this week:

APPETITE TO CHASE? 
- Equity bulls have managed to retain the upper hand so far and the MSCI world index is up almost 50 percent from its March lows. However, earnings may need to show signs of rebounding for the rally's momentum to be sustained. Even those looking for further equity gains think the rise in stock prices will lag that in earnings once the earnings recovery gets underway, as was the case in past cycles. The symmetry/asymmetry of market reaction to data this week -- as much from China as from the major developed economies -- will show how much appetite there is to keep chasing the rally higher.
