Rebalancing
A portfolio structured
around compensated risk factors is organized around
polar risk dimensions. This offers advantages over other
investment strategies when it comes to rebalancing a
portfolio back to its intended structure.
Though not a perfect inverse
relationship nor predictable, periods when large stocks
outperform tend to alternate with periods when small
stocks outperform. The same is true for growth and value
stocks. Portfolio performance varies when risk factors
move in and out of favor. Movements significant enough
to require trading tend to vary systematically, which
brings clarity and purpose to the process of rebalancing.
A portfolio built around
the skill or charisma of active managers has holdings
that vary more randomly across risk dimensions and becomes
harder to rebalance in a logical way. The downside of
this practice is that it encourages investors to chase
performance and depend on the randomness of speculation
as the source of their success. With an actively-managed
approach, rebalancing to a desired portfolio structure
is pointless.
Purpose Wealth conducts
rebalancing trades when it makes sense to do so. This
"contingent" rebalancing process relies upon
a triggering event, such as account deposits/withdrawals
or when asset class positions deviate significantly
from their intended targets. Our primary consideration
is that the benefits of rebalancing must outweigh the
costs.
