For most families, it doesn't matter how much you have saved for retirement, you probably always feel you don't have enough. It's understandable, because while during the asset accumulation phase, you could use dollar cost averaging (DCA) to guide your investment - the lower the market goes, the more shares you will collect, in retirement (or fund distribution phase), you will encounter the DCA's evil twin - the lower the market, the more shares you will have to sell (to generate the same amount of income as in higher market).
Howe to address this problem?
The 3-bucket retirement income system.
