Are there no shortage if things market players need to worry about? It's amazing how long that 'wall of worry' has been up. Yet, the market doesn't seem to be showing it, in fact we are seeing high complacency exist, which may not be a good thing over the long haul. But I have to believe the mountain of concern in trading markets is way overblown, and the market shows it'll continue to overcome cautious behavior. Ideal for a market to rally further than anyone expects.
