Life-cycle funds, among the newest asset allocation fund offerings, are managed according to investors' time horizons and risk tolerances. Partly in response to the appearance of these funds, we examined the relationships among the risk in individual investors' portfolios, their financial-planning time horizons, and their risk tolerances. Generally, we found that portfolio risk increases as time horizon and willingness to take risk increase. This relationship held when we used multivariate analysis. Additional factors related to portfolio risk were found to be the investor's expectations of a future economic downturn, age, education, and marital status.
