Investopedia explains 'Life-Cycle Fund'
Proponents of life-cycle funds cite the convenience to investors of putting their investing activities on autopilot through the use of just one fund, which is managed for them. On the other hand, critics of these funds say that their "one size fits all" approach is suspect. For investors who don't want to take responsibility for their retirement investing, a life-cycle fund may be appropriate. However, for those who want to take the time and make the effort to direct the management of their investments, life-cycle funds should be avoided.
