Do you want to under-perform during all bull markets so it hurts less during the corrections?

If you stayed invested in the broad market through any bubble-pop you would be better off than aggressive diversification and hedging. Unless you can reliably time the tops and bottoms.

Where else will you invest? China? India? Rest of Asia? Europe? South America? Africa? Specific commodities?

Do you believe the next generations in the US will continue to create value or do you think this is the beginning of a perpetual decline?
