Why didn't you add more? It would never go to 0 and if it did, things will be much worse. Get good investments (I think this is a must in a portfolio) and dividend reinvest and buy more on major moves down. There will always be major corrections which can be great to add more. I did that with VTI, VWO, VEA, OAKWX, OAKMX and bought ILB and BOND when they opened. I dividend re-invest. I will buy more on dips. If the market crashes again I will buy a lot more. I purchased AIG way lower, and JPM after the whale. This is a hold. You could be worse off and sold when at $20.
