<prompt> Human: Im curious about rebalancing methods for a portfolio - specifically 401K. If Im following the three fund portfolio strategy, what is the best way to rebalance? Should I simply move the money in my investments to match the percentages of my original asset allocation? Im not sure how most 401Ks work but with mine, I can very easily move money from one fund to another.  <response>: Should I simply move the money in my investments to match the percentages of my original asset allocation? Yes, thats what rebalancing is.
