I would be interested in timing and triggers used by many on this board to rebalance their portfolio allocations. This has been mentioned some, but I didn't find a conversation specifically devoted to various strategies. I recently found the following paper which I thought was interesting:
It's relatively old, early 90's, but may provide some relevant data. I believe it deals with institutional type portfolios and the re-balancing relates to basic stock and non-stock % without getting into any kind of sub allocations.
The paper discusses 2 major classes of approach, calendar based and target/range based (e.g., Larry Swedroe's approach). Gives some performance numbers on calendar (monthly, quarterly, annually) in which more frequent does best, and target/range in which bringing back out of range allocations all the way to target rather than just to within range does best.
Which do you use or do you use a combination? Do you handle sub-allocations any differently than the basic stock/non-stock split? Thanks! Bill
