When it comes to allocating your investments, there are “tactical” ways to go about it – and some of these strategies have very impressive track records. In this special three-part series, you’ll learn three different tactical asset allocation strategies to inspire your investing and boost your portfolio. So last but not least, here’s part three: Vigilant Asset Allocation (VAA).
Tactical asset allocation is a “dynamic” investment strategy – one where you’re actively adjusting your portfolio to take advantage of market trends, aiming to maximize returns while minimizing risks. The best part about tactical asset allocation: it’s relatively easy to implement using exchange-traded funds (ETFs).
VAA is a “momentum strategy”: you invest in asset classes that have recently performed well based on the tendency of them to continue to perform well in the near future. Momentum is a well-studied phenomenon within the academic community. One of the reasons it works is the fact that investors have deep behavioral biases – like herding and extrapolation.
An important concept behind VAA is “dual momentum”, which refers to two types of momentum: relative and absolute. Relative momentum measures how an asset has performed relative to other assets over a certain time period. Absolute momentum, on the other hand, measures whether an asset has actually risen in value over a certain period of time.
You’ll see how VAA incorporates dual momentum in a second. For now, you should know that VAA is an aggressive strategy: each month, it allocates 100% of the portfolio to a single asset from a small basket of either offensive or defensive assets.
VAA trades seven different ETFs, each representing a different asset class or subclass. The ETFs are organized into two different groups, or “universes”: offensive and defensive.
The strategy trades and rebalances monthly. So on the last trading day of the month, you would do the following.
Just as with the Defensive Asset Allocation strategy covered in part one of this series, first calculate a momentum score for each of the seven ETFs. The authors use a “13612W” score – a bit of a mouthful, but here’s how you work it out:
13612W = (12 (p0 / p1 – 1)) + (4 (p0 / p3 – 1)) + (2 * (p0 / p6 – 1)) + (p0 / p12 – 1)
Where p0 = the ETF’s price today, p1 = the ETF’s price one month ago, p3 = the ETF’s price three months ago, and so on.
The first term – (p0 / p1 – 1) – is the ETF’s percentage price change over the past month, and the second term – (p0 / p3 – 1) – is the ETF’s percentage price change over the past three months. You get the idea. Also, notice how the 13612W score overweights the most recent returns: the ETF’s one-month performance is multiplied by 12, its three-month performance is multiplied by a third of that (four), and so on. This gives more recent returns a greater impact on the strategy than older ones.
Look at the 13612W scores of the four ETFs in the offensive universe.
Hold on to the ETF until the last trading day of the following month. Then go back and repeat the steps above. Even if the ETF you end up investing in doesn’t change, repeating the steps above ensures that you stick to the strategy.
Performance tracker AllocateSmartly has compiled robust data on the VAA strategy’s historical performance, even projecting it back to 1970. While looking at this in isolation is all well and good, it’s more informative to compare performance to a benchmark – in this case, a basic 60/40 strategy that invests 60% in US stocks and 40% in US government bonds.
Measured over the past 50 years or so, VAA generated an eye-popping average annual return of 17.7% – nearly double the 60/40 benchmark’s 9.8%. But, as you’d expect from an aggressive strategy that’s always fully invested in a single ETF, VAA’s volatility of 12.1% was higher than the 60/40 portfolio’s 9.8%. Still, VAA’s strong performance means that the strategy generated much higher investment returns per unit of risk.
What’s more, VAA actually displayed less risk by another important measure: maximum drawdown (MDD) – the largest peak-to-trough decline in the value of a portfolio. The VAA strategy’s MDD over the past half-century was 16% – almost half the 60/40 benchmark’s 30%.
VAA has an impressive track record: it has generated excellent investment returns both on an absolute and risk-adjusted basis. Part of the reason VAA managed to avoid large investment drawdowns is its use of absolute momentum: when any offensive assets start to show signs of weakness, the strategy shifts to safer assets like bonds.
All in all, if you apply this strategy to your investments, you may well boost your returns. Having said that, the old investment adage – “past performance is no guarantee of future results” – applies here: the VAA strategy may not necessarily perform well in the future and/or may experience a larger peak-to-trough loss of 16% at some point.
The strategy’s high volatility means it’s not for the faint of heart. And VAA has two drawbacks on top of that. First, it moves into bonds when any of the offensive assets start exhibiting negative momentum. This reliance on bonds has worked well in the past considering the decades-long bond bull market. But going forward, bond yields cannot – mathematically speaking – go much lower. Weak bond returns today – and the prospect of negative returns in the future if bond yields rise meaningfully – could detract from VAA’s future performance.
Second, the strategy is the exact opposite of diversified: it holds a very concentrated portfolio invested in a single ETF. In practice, you should rarely ever invest your entire portfolio in a single fund – so I wouldn’t recommend you implement VAA in isolation. But you could, perhaps, use it for the equity portion of your portfolio. Let’s say 30% of your portfolio is invested in a few stock market ETFs targeting different geographies. You could swap out that allocation for VAA: the strategy is, after all, trying to target the best-performing geographies while switching to bonds when it senses trouble.
And that’s it for our three-part series on tactical asset allocation. We hope you enjoyed these three approaches and gleaned a thing or two to utilize in your portfolio construction.
You might have great investment ideas, but if you don’t get your allocations right, you won’t get the returns you’re after. Luckily, Stéphane has a guide to get your assets in line.
