Using stock data going back to 1871, we show that buying stock on margin when young combined with more conservative investments when older stochastically dominates standard investment strategies--both traditional life-cycle investments and 100%-stock investments. The expected retirement wealth is 90% higher compared to life-cycle funds and 19% higher compared to 100% stock investments. The expected gain would allow workers to retire almost six years earlier or extend their standard of living during retirement by 27 years. Ian Ayres Life-Cycle Investing
