ETFmatic's white-paper: Transparent, peer-reviewed Digital Wealth Management

1. Our principles

Through our series of blog posts we have shared what we believe are the general truths that are applicable to investing. This includes the ample evidence that in general asset allocation trumps stock picking. We’ve covered why we believe ETFs are a good way of investing, and how important it is to pick a strategy that you are comfortable with and then stick with it. The value of saving and investing for the long term, how passive investment instruments usually deliver better returns than actively managed ones. We’ve delved into how this difference is magnified by how we as humans have an unwarranted belief in our ability to pick the winners and to time the market, and how important costs are to investment returns. We’ve also talked about how we are challenging investment assumptions and have analyzed the flaws of the traditional definition of risk profiling and how a different approach can be used to better tailor portfolios to clients needs. This updated white paper explains how we have tied all of these concepts together in our approach to investment management. Beginning with asset allocation we also describe our portfolio implementation, trading and re balancing. From the start our objective has been to build the most tailored and transparent online investment offering, and with this paper we aim to provide you with all the details you need to understand how your money will be managed.

2. Asset allocation

ETFmatic offers portfolios with exposure to two major asset classes: equities and bonds.


Equity instruments grant ownership in a company/companies. This exposure or what is commonly know as a share, is expected to be worth the future earnings one can expect from the company. Earnings generally tend to grow over time for a variety of reasons and, depending on the company region and period of time, can exhibit moderate to high levels of volatility. In a growing economic environment, with low interest rates and inflation, equities tend to perform well as the companies that make up the stock market grow due to their increasing revenues and profits.


Government bonds grant exposure to government credit and interest rate risk, but are most often less volatile than equities, as these instruments are backed by the full faith and credit of a government and have fixed and known income streams for investors (the coupon and final redemption payments are known). They have historically been classified as lower risk investments. The two asset classes tend to exhibit a low correlation with one another over longer periods of time. In a growing economic environment, earnings and profits grow and the shares of companies tend to do well. When investors are risk averse, they tend to allocate to bonds given their fixed payments and limited expected downside. These fundamentally different economic streams of returns (the variability of equities returns versus the fixed nature of bonds) means that historically, these asset classes have been suitable for diversification. Combining two asset classes that provide different streams of risks and returns in different economic environments means your overall portfolio should offer better risk-adjusted returns.


ETFmatic has chosen not to include other asset classes (notably commodities and precious metals, real-estate, or other alternative investment instruments) in our universe. While there are definite benefits to holding commodities within a portfolio we don’t think that the implementation offered through swap-based products, narrow Exchange-Traded Commodities (ETCs) or active funds that charge high fees justify their inclusion. Given our focus on simplicity we also don’t think it merits investing in futures to gain exposure to the asset class. We expect that most of our clients will have some form of exposure to their local real estate market. While we do not want to get into a debate around diversification or hedging of said exposure, we believe that the overall diversification through the broad equity indices is enough for a long term portfolio.

2.1. Asset Classes

Within the two broad asset classes of equities and bonds, we have chosen to target broad indices replicating major markets. On the equity side we have identified six broad indices that taken together represent more than 97% of world’s investable equity markets. On the fixed income side we use two main broad indices for each currency. The first, and most important one, is a government bond index for the home currency. The second varies depending on currency, as can be seen in the table below.

2.2. Index selection

The specific indices we have identified for each currency can be found in the following table .
Asset Class GBP EUR USD
US Equity S&P 500 S&P 500 S&P 500
Europe Ex-UK Equity FTSE Developed Europe ex UK FTSE Developed Europe ex UK FTSE Developed Europe
UK equity FTSE 100 FTSE 100
Japanese Equity MSCI Japan MSCI Japan MSCI Japan
Asia Pacific Ex-Japan FTSE Developed Asia FTSE Developed Asia FTSE Developed Asia

Fixed Income
Home Bonds Bloomberg Barclays Sterling Gilt Float Adjusted Index Bloomberg Barclays Euro Aggregate: Treasury Index Bloomberg Barclays Global Aggregate US Treasury Float Adjusted Index
Inflation-Linked Bonds Bloomberg Barclays UK Government Inflation-Linked Bond Index Bloomberg Barclays Euro Government Inflation-Linked Bond Index Bloomberg Barclays US Government Inflation-Linked Bond Index

2.2.1. Currency Hedging

Currency exposure adds volatility which implies the possibility of both better and worse returns. Currency hedging is a way to protect against the worse returns. Within equities, research indicates that over the longer term there can be no difference between hedged or unhedged returns. We further believe that equities tend to have natural hedging properties within the instrument. When you invest in a company that has product and services all over the world, their different foreign earnings streams will be subject to many different currency movements. When these companies report earnings in local currency they undertake hedging themselves to protect from adverse foreign exchange movements. We therefore chose to use unhedged indices on the equity side in order to achieve an exposure to all opportunities in each target region, including local market returns and their currency effects. As bonds provide investors with fixed streams of returns in a particular currency, we believe not having this income stream in an investor’s base currency could seriously affect the final value of the investment. As the main purpose of a bond allocation has traditionally been to serve as “safe” assets we have opted to buy hedged bond ETFs wherever necessary.

3. Portfolio Construction – One approach: from the straightforward to the complex

We believe that everyone deserves an individually managed portfolio. For this reason we offer our clients two categories of portfolios – Starter and Custom Portfolios. Both categories use the same asset classes, and trade the same ETFs and have the same portfolio management philosophy. Both are managed individually. The big difference is that starter portfolios allow our clients to easily select between 21 asset allocations whilst custom portfolios are for the more sophisticated investors that want to build their own asset allocation. All clients start with a straightforward starter portfolio and can then adjust their portfolios to become more tailored if this meets their investment needs.

3.1. Starter Portfolios

Starter Portfolios are very straight-forward to set up while still giving the client some control over the overall asset allocation. Clients simply select a split of equity and bonds which are suitable for them based on three broad risk categories: Conservative, Balanced and Aggressive asset allocations. More conservative asset allocations will have a higher allocation to bonds (historically safer investments) while more aggressive portfolios will have a higher allocation to equities (historically growth assets). Within the equity portion, we allocate to various regions based on the market cap weighting across the indices (see previous section for overview of the indices we use). Within the bond section of the portfolio we allocate 80% to the local government bonds and 20% to index-linked bonds. The Starter Portfolios allows our customers the following benefits:
  • A straightforward portfolio management solution
  • The ability to select the most suitable profile given their risk and return objectives.
  • Setting a precise asset allocation, from 0 to 100% invested in equities/bonds.
  • Rebalancing their portfolios correctly with increased contributions.
  • Not having to worry about the index selection, ETF implementation, tax-efficient rebalancing and ensuring that the portfolio maintains its’ risk profile as markets and asset classes adapt and change.
The disadvantage with allowing a client to only choose a bond/equity allocation that matches their risk profile is that the portfolio won’t necessarily reflect all their unique preferences. Certain investors will have unique investment views that they would like to implement. That is why we offer Custom Portfolios.

3.2. Custom Portfolios

Custom Portfolios allow our clients complete control over their desired asset allocation. We present the exact same asset classes and regions we use to construct all our portfolios, but allow clients to select their own target percentage weight in each. The underlying ETFs are still chosen by us, as discretionary manager, and are the same as the securities used in the rest of our client portfolios. The target weight percentage of each asset class can be changed at any time, allowing more freedom to express long-term investment views. With Custom Portfolios, someone with a specific investment view or desired asset allocation can easily construct a portfolio. Individuals with a bias (both positive and negative) towards a particular asset class or region can overweight or underweight that ETF to match their chosen investment view. The management and implementation of that asset allocation is then simply handed over to us. The disadvantage of the Custom Portfolios is that a client would have to know which asset classes and combination thereof (the risk profile) are suitable for them. Individuals with strong investment views could also change their asset allocation frequently. However, this could not always be to the benefit of their long term investment goals and would require someone with knowledge and expertise in asset allocation.

4. Instrument Selection

As mentioned in our principles, there is ample evidence that shows that asset allocation has far more of an impact on your returns than what specific funds or ETFs you pick within any given asset class. The indices that we have selected to represent each each asset class have, in most cases, multiple ETFs tracking them. So how do we choose which ETFs to use?

4.1. ETF Choice

There are objective criteria that can be used to prioritise which ETF would, ex ante, most likely be a more appropriate selection than others. The criteria that we use include, in no special order of priority:
Criteria Comment
Issuer This looks at the issuer of the ETF. Their track record, credibility & reputation, how many assets under management (AUM) do they have?
AUM & Age How long has the ETF been around for and how large is it in terms of AUM? If it is relatively new and with relatively low AUM? How serious do we judge the issuer to be? How large a share of the ETF’s AUM are our clients likely to represent?
Total Expense Ratio How expensive will the ETF be over the longer term?
Tracking Error & Tracking Difference How good a job does the ETF do at tracking its index?
Distribution Policy Does the ETF distribute the dividends it receives, and, if so, how frequently?
Tax Status Does the ETF issuer report the relevant tax information for it to be eligible to be included in tax wrappers?
Tax Domicile Where is the ETF domiciled, and what are the tax treaties between the ETF’s country of domicile and the countries where the underlying assets are domiciled? How does this impact the taxation of dividend distributions?
Accounting Currency How well does the ETF’s internal accounting currency match the currencies in the countries where the underlying assets are domiciled?
Trading Currency Does the ETF trade in the currency of the portfolio in which it is to be held or would there be the potential for inefficiencies due to currency exchange?
Listings On what exchanges does the ETF trade?
On Exchange Liquidity & Spreads How liquid is trading in the ETF on the exchanges where it is listed? How costly would it be to trade on said exchange?
However, it is worth to keep in mind that not only is it likely that the relative ranking of ETFs replicating any given index may change over time, but there are also client or portfolio specific circumstances that may make it so that the ETF with the “highest” objective ranking is not the best choice for a given client.

4.2. Multiple ETFs per Index

When it comes to monitoring and selecting the best ETFs this invariably means occasionally switching from one provider to another. Based on the characteristics we detailed above, which we continuously monitor. Traditionally this has meant selling all your units in one ETF in order to buy another. In line with ETFmatic’s objective of personalising each client’s portfolio, our platform is able to handle multiple ETFs tracking each index and to switch between them for a given client’s circumstances. As we continue to evolve our platform we will, therefore, increase the number of ETFs we hold for a given Index. The number of ETFs per asset class or region could vary for each client as we aim to offer better and more personalised product implementation in a far more tax efficient way. Below is an overview of the ETFs that we currently use to track the different indices.

5. Ongoing Portfolio Management

So far we have provided details around how we construct the target allocations for our different portfolios. In this section we describe how we actually manage them on a day-to-day basis.

5.1. Updating Target Allocations

Starter Portfolios have static asset allocations that are reviewed and update once per year. As we currently use the MSCI ACWI as our representative index, we review and update the weights in our Starter portfolios to match the regional weights and market capitalisation of the world equity markets. The target allocations of Custom Portfolios are defined by the client, who also decides how frequently to change the targetWe calculate the best way of investing the funds to get each portfolio as close to the target allocation as possible.

5.2. Investing Cash

Whenever our clients invest funds, whether an initial amount or recurring contribution, we allocate the cash as mathematically accurate as we can to reach the target asset allocation of the portfolio. Based on the size of the contribution this might result in all the ETFs that make up the portfolio being purchased in the right combinations (weights). For smaller contributions, we will purchase what ETFs we are able to given the amount invested and the market price of the instruments. Small initial and recurring investments will mean that it may take some time for the portfolio to reach the target allocation.Given that the bid and offer prices of ETFs constantly move in the market we implement a safety buffer in our calculations as a safeguard against overspending any cash. This means that once your funds are invested there might be a small residual of cash left in the portfolio. Our system will allocate that cash on the very next trading window and continue to do so as long as the funds left in the portfolio can be allocated to at least one unit of one of the ETFs in the portfolio. We, therefore, aim to invest all cash as mathematically accurate as possible, investing to the nearest decimal when we are able to.

5.3. Portfolio Rebalancing

Our two portfolio offerings all have target weights for the different asset classes:
  • With our Starter Portfolios these weights are updated once per year to reflect changes in the market caps of the different indices.
  • The target weights of Custom Portfolios will change if a customer decides to change their asset allocation or liquidate their portfolios.
In deciding our rebalancing methodology, we reviewed several research papers that delved into the ideal frequency and best methodologies for rebalancing. We looked at the assets we use to construct our portfolios in terms of trading and settlement cycles. We considered the frequency of our asset class price feeds updates.With this in mind, we have implemented a portfolio rebalancing methodology that uses twice weekly and semi-annual looks along with set tolerance bands and inner rails relative to a portfolio’s target weight.

5.3.1 Tolerance Bands and Inner Rails

Being dogmatic about rebalancing a portfolio back to its target weights can often generate unnecessary trades where the tax implications outweigh the benefits of bringing the portfolio back to the exact target weights. Research suggests that a better way to manage rebalancing is to allow portfolios to drift slightly from the target allocations before assets are sold off in order to bring the portfolio back to target.How far from the target a portfolio is allowed to drift is commonly referred to as the “tolerance bands”. Our aim is to set tolerance bands in place that are wide enough to allow for natural drift to occur and prohibit costly frequent rebalancing, whilst narrow enough so that the portfolio’s asset allocation mix adheres to the long-term chosen risk profile.The same research also suggests that, when selling off assets to rebalance, it is possible to be flexible about how close the portfolio should be brought to the target weights to further minimise the implicit and explicit costs of trading. This flexibility is bounded by what is usually referred to as the “inner rails.”We have chosen to set tolerance bands that are 20%, on a relative basis, on either side of a portfolio’s policy weight. We have further chosen relative weights of 10% for what we define as inner rails. These percentages were used and they were most compelling in the research in terms of portfolio returns, frequency of trades (reducing costs) whilst adhering to a portfolio’s policy weights.We use our upper and lower tolerance bands to trigger rebalancing and our inner and upper rails as the points to rebalance to. Rebalancing to inner and outer rails rather than the exact policy weights will hopefully ensure trades (implicit and explicit costs) are minimized whilst the policy weights and risk profile of the portfolio is strictly maintained.The tolerance bands and rails define what triggers a rebalance but do not determine when it is to be reviewed and implemented. There is a variety of research on how often a portfolio should be rebalanced. Given our focus on costs, we have segmented our frequency of rebalancing for portfolios as follows:5.3.2 Portfolios of GBP, USD, EUR 25,000 and above We looked at the minimum size of trades and potential frequency and decided for portfolios in this bracket to implement a twice weekly look or investigation policy. This means that twice per week we compare the live weights of each portfolio (= individual portfolio holding a balance of 25,000 EUR, GBP or USD and above) to lower and upper tolerances and, if necessary, take action to bring the live weights to the inner rails if possible.We have deliberately implemented wider tolerance bands (20%) and more frequent investigation (twice weekly) to ensure that we do not necessarily rebalance frequently (keeping costs to a minimum), but that, given extreme market movements, we can adjust portfolios accordingly.

5.3.3 Portfolios below GBP, USD, EUR 25,000

For portfolios below our threshold amount, we have deemed that the size of the trades and the costs involved do not justify a frequent look methodology.Furthermore, a portfolio that is built through small monthly contributions and dividend payouts on existing holdings will often only reach the chosen target asset allocation over time. In this instance rebalancing would have no benefit besides adding costs.For this segment of portfolios we have therefore implemented a semi-annual look and rebalancing methodology. We use the exact same tolerance, inner rail bands and rebalancing logic. This means that on a semi-annual basis we will compare all portfolios of less than the threshold amount to their tolerance bands. Any live weights outside of tolerance are brought back to inner and outer rails where it is possible to do so.

5.4. Trading

Once we have generated the instructions for what trades we should do on each portfolio, we move on to executing those instructions. We first do an internal netting and aggregation of the instructions and then we go to trade the net demand or supply in the market.Client Account Internal NettingWe look at each client account to see if it has multiple portfolios, and if so how much of the rebalancing can be done by moving money and assets between the different portfolios. Since this is all done within the same account, it does not trigger any tax consequences.Global Aggregation and NettingSecondly, we look at to what extent we can net off transactions across client accounts. This has the benefit of reducing the volume we need to place into the market, thereby reducing both explicit costs as well as our overall impact on the market pricing of the ETFs (the implicit costs) we trade in. Trading After netting and aggregating, we take the remainder and send orders to market. Currently, we trade in the market at least twice per week. The price we get when trading in the market is also the price that is used for the internal netting.The day after we have completed all the trading we send all our clients a transaction report summarising exactly what trades we did on their behalf.We also ensure that each portfolio receives its’ due dividends and that the clients are properly informed of the dividend distributions that their portfolios receive. 5.5 Fees & Portfolio Administration Fees We only charge fees for the assets we manage on your behalf. ETFmatic charges an annual “management fee” of 0.48% of your assets under management. The ETFs we invest in will also have their underlying Total Expense Ratios (TERs) which we are unable to avoid. The total weighted average costs of the TERs will vary depending on the asset allocation chosen. Currently the maximum weighted average cost is roughly 0.25% with the minimum being roughly 0.07%. On average our GBP, USD and EUR portfolios have a TER of 0.13%. These numbers are only indicative and will change as the ETFs in the portfolio change. The Total All-In Costs will therefore range between 0.73% and 0.55% for a standard portfolio. We do not charge our clients any additional transaction, custody or maintenance fees.As part of our commitment to transparency we also send all our clients monthly summaries of fees so that it’s clear exactly what we charge for the service we provide.ReportingWe provide our clients monthly account statements. These statements detail exactly what ETFs are held, and the number of units and valuation of each holding. We also provide a summary of the previous month’s movements, including how much new money was invested in the account, how much was received in dividends, the impact of our fees, and finally, how much the account changed in value due to fluctuations in market prices.At the end of each tax year we also send out a consolidated summary of all purchases, sales and dividend payouts, which can be used by each client to complete their tax filings.

5.6 Liquidation of Portfolios and Withdrawals

5.6.1 Full Liquidation

We recognize that sometimes the unexpected happens and a client will want to liquidate a portfolio ahead of their initial planned investment time horizon. We have made this process simple by allowing our clients to simply click on the close goal button within their dashboards. This informs us to liquidate the portfolio, and during the next trading window, we will sell off the assets held in the portfolio.Once all the trades have settled and the cash has become available we will transfer the proceeds back to the client’s bank account. Our policy is to transfer the proceeds back to the bank account from which the client made the initial transfer from.Due to the trading cycles we currently work with, this can take up to six working days depending on when the client requests the liquidation and withdrawal.We do not charge transaction or transfer fees to clients when they withdraw their money or liquidate their portfolios.

5.6.2 Partial Withdrawal

We know that clients use the investment returns in their portfolios to fund personal life expenses and therefore require the ability to withdraw funds periodically. We have made this incredibly simple with our withdraw funds button within our portfolio dashboards. This allows a client to specify the amount (to the nearest hundred) that they would like to take out of their portfolio.The withdrawal functionality provides the ability to take up 90% of the portfolio as long as the amount invested left remains above our minimum investment of GBP/USD/EUR 100. We have chosen this 90% threshold, as taking amounts greater than this would effectively be the same as liquidating the entire portfolio.Once a we have received the instruction the partial withdrawal will go into our next rebalancing window. Our system first looks to see what cash is already available in the portfolio and puts that to one side. Our selling methodology then focuses on selling any or all assets back down to the target weights of the portfolio. Starting with the most overweight assets and moving down to the least overweight our system will iteratively sell down any holdings until the required cash is raised. Therefore not only raising the required funds, but also leaving the portfolio as close to the target asset allocation as possible given the size of the portfolio.Given our trading windows, cash will be available in roughly 3 to 7 working days. Our policy is to transfer any cash back to the bank account from which the goal was initially funded.

5.7 Portfolio features

As part of the drive of ETFmatic is to offer a more and more personalised investment management solution over time. It is with this in mind that we constantly offer portfolio management features to help clients achieve their desired investment objective. Below are the list of features that clients and customise their portfolio management with:5.7.1 GlidingGliding is a feature which enables you to opt in for an automated change in your portfolio asset allocation over time, as you draw closer to your stipulated investment goal.When an investor decides on the time horizon of their portfolio, they no doubt have an end goal in sight. As the goal draws nearer, the assumption is that you would most likely allocate less to growth assets (that have greater volatility) and more to historically conservative asset classes.This potentially helps to protect the final portfolio value as you draw nearer to that moment in time when a defined amount of capital may be needed. This process of: (i) starting out with your defined target asset allocation and (ii) slowly adjusting the asset allocation over time may become a very manual process. It could mean changing the risk profile of the asset allocation to become more conservative and, to that effect, having to time it just right when doing that.Our gliding feature allows clients to specify their current target asset allocation, their desired end glide-path asset allocation and the time horizon over which they would like to invest. The system will then calculate the desired allocation changes required over the time horizon and automatically adjust the asset allocation of the portfolio to ensure the final target allocation is achieved.

5.7.1 Gains Harvesting

Capital gains harvesting means strategically substituting ETFs within an index to realise capital gains while maintaining the overall allocation to an asset class.It operates by identifying and selling those ETFs that have increased in value and replacing them with similar ETFs to ensure that we maintain the same asset allocation exposure for our clients.This functionality may be useful to clients who either live in a country that provides for a tax-free allowance, or know that they can offset the capital gains harvested by ETFmatic against losses in other parts of their overall investment portfolios.How useful this turns out to be to individual clients will of course depend greatly on their personal circumstances and we strongly suggest that anyone who is not familiar with concepts like capital gains tax or tax-free allowance consults with a professional tax advisor before deciding to turn on the functionality on their account.
