Lifecycle funds
Each of the eleven L Funds is a diversified mix of the five individual funds (G, F, C, S, and I). They were designed to let you invest your entire portfolio in a single L Fund and get the best expected return for the amount of expected risk that is appropriate for you.
Every quarter (three months), the target allocations of all the L Funds except L Income are automatically adjusted, gradually shifting them from higher risk and reward to lower risk and reward as they get closer to their target dates. When an L Fund reaches its target date, it goes out of existence and any money in it becomes part of the L Income Fund, which generally keeps the same target allocation. For example, in 2025, the L 2025 Fund will be rolled into the L Income Fund.
One of the important things about the L Funds is that they stick to their target allocations for a full quarter regardless of what the markets do. Every trading day, some of the individual funds in an L Fund will do better than others. At the end of the day, the individual funds that did better will make up a higher percentage of the L Fund than the ones that did less well. To maintain each L Fund’s target allocation, we rebalance it at the end of every trading day. We do this by buying and selling the individual funds that make up the L Fund so that the percentages go back to what they were at the beginning of the day. In effect we’re buying low and selling high at the end of every trading day.
