Well, after much deliberation over the aforementioned L2050 fund, I have decided to let it roll.
Both the S&P and the EFA (I-Fund tracker) have significant headroom above the S Fund, and as you that are knee-deep in snow these days know, breaking new ground requires substantially more effort than retracing your previous path.
Thus, I am more than 85% in agreement with the initial structure of the L2050, and it mirrors my waning stimulus/recovery period philosophy that after the initial pop, the big caps step up in sustained fashion.
Maintaining L2050 100% COB.
