I would be very careful of rebalancing as a rote act. You can be moving money from well performing assets to poor performing assets. Rebalancing is the technique used by some advisers, Rhe real reason some advisers use rebalancing is that when combined with diversified holdings, it avoids taking too bad of a hit with bad choices. The problem with it is that it can really hurt the performance of some of your holdings.
Few things to think of:
Where do you think the market is heading?
What is your risk tolerance?
How long can the money be tied up for investing?
