SMAs & MODEL PORTFOLIOS
based signals to a centralized overlay
manager who then executes trades
at the account level, taking on more
complete discretion.
Active overlay tends to produce better
tax optimization and more consistent
portfolio-wide customization, precisely
because one party can see and
coordinate the entire account rather
than each manager operating with
tunnel vision on their own sleeve.
DISTRIBUTED VERSUS
CENTRALIZED DECISIONMAKING
A third axis worth understanding,
particularly for advisors who want more
hands-on involvement, is how overlay
decisions are made. They can be
distributed, with a relationship manager
or trust officer setting individual rules
for individual client accounts, or
centralized, where allocation decisions
are made at the firm level and applied
more uniformly. Distributed overlay
gives an advisor more granular
control. Centralized overlay tends to
be more scalable and is often what
asset managers are more comfortable
releasing their models into, since it
reduces the number of parties who can
modify a model’s intended execution.
THE HONEST
TRADE-OFF
What active overlay
costs an asset
manager
Active overlay typically produces better
tax optimization and more consistent
customization, but it asks underlying
managers to hand execution authority
to a centralized overlay manager. Some
managers are genuinely uncomfortable
with this, wary of losing control over how
their own strategy gets expressed in a
client’s account. That discomfort is a
legitimate input to a manager’s fit, not
just a technicality.
HOW AN OVERLAY ACTUALLY
DECIDES WHEN TO TRADE
Everything described so far explains
what an overlay coordinates. It’s worth
also explaining how it decides when
to actually act, since “continuously
monitoring the account” doesn’t mean
trading continuously. Most overlay
systems operate using tolerance
bands, a permitted range around each
target allocation, typically expressed
as a percentage drift, within which
the account is left alone even though
it’s technically no longer at its exact
target weights. A position drifting from
20% to 21% of the portfolio might sit
comfortably inside its tolerance band
and generate no trade.
The same position drifting to 24%
might breach the band and trigger
a rebalance. This matters practically
because tighter tolerance bands mean
more frequent trading, which means
more realized gains and losses (useful
for harvesting, costly if it generates
unwanted short-term gains), while
wider bands mean less trading activity
but more allocation drift between
rebalances. An advisor evaluating an
overlay provider should ask directly
what tolerance bands the system uses
by default, and whether those bands
can be tightened or loosened for a
specific client’s tax sensitivity or risk
tolerance.
A system with fixed, non-adjustable
tolerance bands is offering less real
customization than one where this
parameter is a client-specific setting.
CASH MANAGEMENT AS ITS
OWN OVERLAY FUNCTION
A less visible but persistent overlay
responsibility is managing cash that
accumulates from dividends, interest
payments, and partial liquidations
before it’s reinvested or distributed.
Left unmanaged, cash can sit idle in a
low- or zero-yield sweep account for
21
longer than necessary, quietly dragging
on returns in a way that never shows
up as a headline cost but compounds
over years. A well-built overlay system
sweeps idle cash into a yield-bearing
position on a defined schedule and
manages the minimum cash buffer
needed for anticipated distributions or
fees, rather than treating cash as an
afterthought between rebalances.
This is a small mechanical detail
relative to the tax-management and
consolidation themes that dominate
this chapter, but it’s a legitimate duediligence question precisely because
it’s the kind of detail that’s easy for a
platform to under-invest in without it
ever becoming visible to an advisor
who isn’t asking about it directly.
WHY THIS CHAPTER MATTERS
MORE THAN IT MIGHT SEEM TO
Overlay management is, in a sense,
the resolution to nearly every
operational tension raised earlier in this
guide. It’s what lets a UMA actually
consolidate tax management (p. 12),
what closes the drift risk inherent in
model-only delivery (p. 17), and what
a sophisticated TAMP is increasingly
building directly into its platform rather
than treating as a premium add-on
(p. 14). For an advisor evaluating a
platform or a UMA provider, the single
most useful question to ask isn’t “do
you offer overlay management,” since
nearly everyone will say yes.
It’s “is that overlay a tool coordinating
account-level allocation, or a manager
taking on real discretionary authority
across my client’s entire portfolio?”
Those are very different services
wearing the same label, at very different
price points, and the gap between them
is exactly where a lot of underwhelming
client outcomes quietly originate.
