Tactical asset allocation: how rules shift your mix

Written by the Tactfolio research teamPublished Data as of 7 min read

Tactical asset allocation is a way of investing where rules change a portfolio’s mix when conditions change. The rules read signals like price trends, momentum or economic data. Then they move money toward assets that look strong and away from weak ones, often into bonds or cash.

Key points#

  • Asset allocation is how you split your money between stocks, bonds, cash and other assets.
  • A strategic allocation picks a fixed mix and keeps it. A tactical allocation lets rules change the mix.
  • Common signals are trend, momentum and economic data.
  • In past crashes, tactical rules often lost much less. In strong bull markets, they often lagged.
  • Every result on this page is a hypothetical backtest, not a promise.

What is tactical asset allocation?#

Tactical asset allocation (TAA) is a set of rules that moves money between asset classes as markets change. An asset class is a group of similar investments, like US stocks, foreign stocks, bonds, gold or real estate.

Asset allocation means dividing your investments among assets such as stocks, bonds and cash, says the SEC’s Investor.gov. Tactical adds a second step. It checks a signal on a schedule, often once a month. Then it changes the mix based on what it sees.

TAA is one branch of algorithmic trading, where written rules make the calls instead of feelings. Most tactical rules ask one of three questions:

  1. Trend. Is the price above its average over the last several months? That is the core of trend following.
  2. Momentum. Which assets rose the most over the past few months? Our guide to momentum explains why that can matter.
  3. Economy. Is a number like the jobless rate getting better or worse?

Strategic vs tactical asset allocation#

Strategic asset allocation picks a target mix and holds it for years. Tactical asset allocation lets the mix change when the signals change.

StrategicTactical
What sets the mixYour goals, time frame and comfort with riskRules that read market or economic signals
How often the mix changesRarely. You only reset it to the targetOften, sometimes every month
Typical example60% stocks, 40% bondsHold each asset only while it trends up
TradingLittle, mostly resetsMore trades, so more costs and taxes
Main weak spotRides every crash all the way downLags in fast rallies, and false signals cost money
Main hopeSteady growth with little workSmaller losses in long bear markets

A well-known strategic mix is the 60/40 portfolio. It holds 60% in stocks and 40% in bonds. On a schedule, it sells some of the winner and buys the loser to get back to 60/40. That reset is called rebalancing.

A tactical rule might hold the same assets. But when one of them turns down, the rule can move that part to cash. Many investors do both. They keep a strategic core and put a slice into a tactical rule.

How does a tactical strategy decide what to hold?#

A tactical strategy checks its signal on a fixed date and does what the signal says. There is no gut call.

Mebane Faber’s model is a well-known example. He published it in 2007 in a paper called “A Quantitative Approach to Tactical Asset Allocation” and updated it in 2013. The Global Tactical Asset Allocation version on Tactfolio works like this:

  • Split the money into five equal parts: US stocks, foreign stocks, 10-year Treasury bonds, commodities and real estate.
  • On the last trading day of each month, check each part on its own.
  • If a fund’s price is above its 10-month average, keep it. If not, move that part to Treasury bills until it recovers.

Some researchers go further. They use statistical models to guess which hidden state the market is in, such as a Markov regime model.

Treasury bills are short-term loans to the US government. In these rules they act like cash. So in a calm year the model may hold all five funds. In a long slump it may hold mostly Treasury bills.

A worked example with round numbers#

Say you put $10,000 into this five-part model, $2,000 in each part. At the end of the month you check each fund against its 10-month average.

FundPrice vs 10-month averageWhat the rule holds
US stocksAboveUS stocks, $2,000
Foreign stocksAboveForeign stocks, $2,000
Treasury bondsBelowTreasury bills, $2,000
CommoditiesBelowTreasury bills, $2,000
Real estateAboveReal estate, $2,000

This month you hold 60% in three funds and 40% in Treasury bills. Next month you check again. If bonds climb back above their average, that $2,000 goes back into bonds.

What do the backtests show?#

Tactical rules have often lost less in long bear markets, but they have also trailed in strong years. A backtest shows how rules would have done on past prices. It is hypothetical, and our backtesting guide explains why past results can mislead.

Tactfolio’s backtest of Faber’s five-part model shows both sides. These figures run from mid-2007 to September 25, 2026. They use daily prices with dividends reinvested and a 0.05% cost per trade (Tactfolio, as of September 25, 2026):

  • In 2008 it lost less than 2%. The S&P 500 lost 37% that year.
  • Its worst drawdown was about 15%, from April to August 2011. A drawdown is how far a portfolio falls from its last high point. The S&P 500’s worst drawdown in that time was more than half. Still, the model took until March 2014 to get back to its old high.
  • It grew about 5% a year. That trailed a plain 60/40 portfolio over the same years.
  • In the strong stock years of 2019, 2020 and 2023, it gained only about 4% to 5%.

So the rule did its job in 2008. It paid for that with lower growth in the years after.

Other tactical strategies to study#

Tactfolio’s classic strategies library holds 75 rule sets, each with its source, rules and backtest. A few well-known tactical ones:

StrategySignalThe idea in one line
Dual momentum12-month returnsHold US or foreign stocks, whichever rose more, unless stocks trail Treasury bills. Then hold bonds.
Vigilant Asset AllocationWeighted momentumHold the strongest of four assets. If any one turns weak, move to bonds.
Defensive Asset AllocationTwo “canary” assetsWatch two warning assets to decide how defensive to be.
Global Tactical Asset Allocation10-month averageHold each of five assets only while it trends up.

Common mistakes#

  • Expecting a rule to dodge every drop. A fast crash can hit before a monthly signal turns.
  • Changing the rules after a bad year. That bends a backtest to fit the past.
  • Judging a rule by its best year. Look at its worst drawdown and its dull years too.
  • Forgetting taxes. More trades in a taxable account can mean more capital gains tax.
  • Skipping the baseline. Compare every tactical rule with a plain 60/40 mix, not only with the S&P 500.

Try it on Tactfolio#

Tactfolio is built for rules like these. Open the Global Tactical Asset Allocation page, read every rule and see its hypothetical backtest next to the 60/40 portfolio. Then copy it, swap a fund or change the average in the strategy builder. These strategies run on daily prices and hold long positions in US-listed stocks and ETFs. You can run one in a paper account or in your own Alpaca account. Our step-by-step guide shows how to automate an ETF rotation strategy.

Common questions#

What is the difference between strategic and tactical asset allocation?#

Strategic asset allocation picks a fixed mix, like 60% stocks and 40% bonds, and keeps going back to it. Tactical asset allocation lets rules change the mix when signals like trend or momentum change. Many investors use a strategic core with a tactical slice.

Is tactical asset allocation the same as market timing?#

It is a kind of market timing, but it follows fixed rules. A person timing the market decides by feel. A tactical rule makes the same call every time the signal fires, and you can test it on past prices first.

Does tactical asset allocation do better than buy and hold?#

Not always. In Tactfolio’s backtest, Faber’s model lost far less than the S&P 500 in 2008. But since mid-2007 it grew more slowly than a 60/40 mix. Results depend on the rules and the years you look at.

How often does a tactical portfolio trade?#

Most classic tactical rules check once a month. Many months nothing changes, so the real number of trades is often lower. Each trade has a cost, and in a taxable account it can create a tax bill.

Is tactical asset allocation good for beginners?#

It can be, if the rules are short and written down. The hard part is sticking with them through years when they lag. Read a strategy’s worst years before you start.
