The Relevance of Multi-Asset Investing

Updated: May 18

We all know that the difference between a comfortable retirement and an uncomfortable one is almost too huge to contemplate. And yet you may be making a simple and irreversible mistake that could ruin the chance of buying those cruises in the sun or leaving something for your offspring.

"Sensible investors for centuries have been spreading their investments across a range of assets"

The mistake I am referring to is having the wrong asset allocation for your retirement savings. Specifically, owning too many government bonds and too few equities. Thirty years ago, buying and holding to maturity the 17-year Gilt would have made you £474,350 of real capital on an initial investment of £100,000. Buy the 1 ¼ % 22/11/32 gilt today and you will lose £146,723 of real capital (I’m using an inflation-linked bond as a proxy for what to expect in real terms from nominal bonds).


Never before have multi-asset funds and their core function of asset allocation been more important.


Hopefully, I now have your attention so let’s take a few steps back.


First, multi-asset investing isn’t new. In fact, it’s as old as the hills. Sensible investors for centuries have been spreading their investments across a range of assets.

But what may be changing is how asset allocation should be determined.


When I began my career in 1988 with a large UK fund management house, most of the firm’s assets under management were “multi-asset” - in the form of defined benefit pension scheme assets. Many of these funds had around half their assets invested in UK equities, another fifth or so in overseas equities, another fifth in bonds and the rest in property and cash. To all intents and purposes they were multi-asset funds. We just didn’t call them “multi-asset”.


Then, over the course of the next couple of decades, the consultants took over, recommending to pension fund clients which manager they should select to manage which bucket of assets. They themselves would take on the job of asset allocation, while fund managers would be picked on the basis of their selection skills in equities, bonds or other asset classes.


To be fair to the consultants, the asset allocation function was ripe for an overhaul. At the firm where I started, it was the manager of the UK equity portion who was the central figure, with the job of asset allocation left to one individual who every quarter would look at the positioning of other pension funds as provided by CAPS or WM and tweak weightings accordingly. It was not sophisticated and the investment consultants, with their clever mean-variance optimization models, had a field day.


However, although clever, these models were flawed. If the volatility of a particular asset class fell, the models, which sought to maximise volatility-adjusted returns, would recommend increasing the allocation to that asset class.


Equities are most volatile when they’ve just crashed and least volatile towards the end of a bull market or sustained rise. So the models were essentially programmed to buy high and sell low. Not one of the better investment strategies in my humble opinion.


These weaknesses were painfully exposed during the global financial crisis and many have since been searching for a better way of making asset allocation decisions.


There is plenty of academic research that finds strong links between the starting valuation of a market or asset class and subsequent medium-term returns. This can be understood most easily with inflation-linked safe haven bonds. A bond on a real yield of 5% will do better than one on 4% (we have chosen safe haven bonds so neither default).


With equities it is a little less intuitive. Those who believe in efficient markets would argue that a high dividend yield simply means that markets are discounting the ‘fact’ that dividends are going to fall. In reality this is not the case: high yields in relation to historical averages portend above average returns and low yields the opposite.


Yale’s Bob Shiller has done a lot of research in this area and he argues, as many others have also since, that the cause of this apparent market inefficiency is behavioural. Namely, that animal spirits from time to time cause investors to herd, driving valuations either to unsustainably high levels or to unsustainably low ones.


So, an asset allocation model that is based simply on valuation (dividend yields in the case of equities, real yields in the case of safe haven bonds, or spreads in the case of high yield bonds) we think makes a lot of sense.


Of course a lot of the time valuations will be close to their historical average. That’s OK, asset allocation does not have to add value all the time. Waiting for the aforementioned extreme valuations to come along, then pouncing, is a strategy that should produce good results.


All this talk of extreme valuations brings us back nicely to where we started. Long-term real government bond yields in most if not all advanced countries are now negative. It’s certainly possible they will perform well in the short term (if real yields or inflation fall further) but over the longer term one is likely to lose.


What could go wrong? For long-term Gilts to continue to perform as well in real terms as they have over the last 30 or so years, future inflation would have to average around -5% per annum. Never before has there been deflation anywhere close to this. The worst 20-year period of deflation was from 1317 to 1337, when consumer prices in the UK fell 42 per cent (related to the Great Famine of 1315-17 and other natural disasters that followed soon after).


This is far cry from what would be required to generate the 6.9% real return achieved by buying and holding to maturity the 10% Treasury Stock 2003 issued on 24 January 1986.

If you define risk as volatility, be my guest and load up on long-term Gilts – the UK government has its own printing press so they’re never going to be that volatile. But if you worry as we do about the potential for permanent loss of real capital, then please beware.


Of course it’s all very well suggesting that you steer clear entirely of the asset class that has in the past been the foundation of a balanced portfolio, but what might you buy instead?

For those not inclined to load up on equities - which anyway tend to be less risky than is generally perceived because companies have, unlike bonds, the scope to adapt to their environment - we would look at what we call specialist assets.


For us, these are listed closed-end vehicles that invest in assets such as property, wind farms, planes, infrastructure, and peer to peer lending platforms. They generally have decent yields, so offer a good alternative to bonds. But they also have stable cash flows that tend to be index linked, so offer a good alternative to equities.


Multi-asset investing and asset allocation have never been more important. Get it wrong, and you can wave goodbye to that cruise ship as it sails over the horizon.
