Much of the attention this week will no doubt be on how the impending General Motors (NYSE: GM) bankruptcy will shake out, as well as the usual economic concerns: Has the housing market bottomed? Will oil prices keep rising? Is the employment situation getting any better? And so on (see highlights of the economic calendar below).
