Investing during retirement is entirely different than investing for retirement. Different strategies are required for the accumulation and distribution phases. During the accumulation phase, it may be appropriate to take moderate risks in return for the prospects of higher returns. A young person with a very long time horizon until retirement and a high risk tolerance might invest her entire portfolio in stocks. During retirement, a much more conservative portfolio is generally called for. That's because the requirement to generate periodic withdrawals to produce income introduces a risk that the portfolio might self-liquidate.
