A big thanks for all your comments and suggestions (especially @Dr.PI), which cleared up some aspects and helped me evaluate my options.
The decision came down to choosing between VWRD (Vanguard’s FTSE All-World ETF) with a TER of 0,22%, and a combo of VEVE (Vanguard’s FTSE Developed World ETF) and VFEM (Vanguard’s FTSE Emerging Markets ETF) in a 90%/10% allocation with a combined/average TER of 0,13%.
Assuming for the sake of this post that the two options are equivalent (not quite in their composition, a quick look at the factsheets will tell us that the VWRD contains 3784 number of stocks, and VEVE+VFEM 2254 + 1893 = 4147 number of stocks) and offer a similar return, the difference of TER (0.09%, calculations below made with an online compound interest calculator) would result in:
- One time investment of 100k with an annual return of 8% after 20 years : 492.7k
- One time investment of 100k with an annual return of 8.09% after 20 years : 501.5k
- Over-performance of VEVE + VFEM → 1.8% of the portfolio over 20 years.
Or a second variation:
- One time investment of 10k + monthly contributions of 1k with an annual return of 8% after 20 years : 638.3k
- One time investment of 10k + monthly contributions of 1k with an annual return of 8.09% after 20 years : 645.8k
- Over-performance of VEVE + VFEM → just under 1.2% of the portfolio over 20 years.
The extra (non-recurring) acquisition/exchange fees for buying two funds per month compared to just one are negligible over the long term (see a comparative overview of the commissions with IB below).
– However, despite this obvious advantage, I decided to invest in VWRD as my core ETF going forward, and not only for the sake of simplicity and “laziness”. Let me explain.
As (mostly) passive investors and Bogleheads, we know VT (US based) or VWRL/VWRD (IE based) to be an ideal solution for a well diversified, simple investment covering the world stock market. So it makes sense to take VWRD (in my case) as the benchmark for the returns I was looking for long-term.
And the more I looked at it, the more I realised that assigning the combo of VEVE + VFEM a clear advantage just because of the overall reduced TER (0,13% vs 0,22%) would be wrong.
-
The lower TER is not the only variable influencing returns in this comparative scenario.
Even assuming the two options were perfectly equivalent, setting up and maintaining an exact and correct (90/10% or 89/11%) weighting between the Developed and Emerging Markets ETFs through monthly contributions and even monthly re-balancing is technically impossible.
-
As a result slight deviations of the allocation would occur constantly and influence the short- and consequently the long-term performance of the portfolio, and likely so in a matter that could very well negatively compensate for the 0.09% advantage that the TER had given in the first place.
-
Even if these slight deviations would cause the opposite effect, and in fact improve the returns of the two ETF portfolio over VWRD, this should be attributed purely to luck. Or put another way, to the inadvertent active investing component that was introduced into the equation.
-
And if one realised this, why not skew the allocation even further, and improve on this “luck”? Resulting in an active approach investing with its increased risks.
Which leads me to this - in my opinion, for a truly passive broad based index investor, the two ETF portfolio should be avoided - what do you guys think?
A whole different matter is when these two ETFs are used in a different way in one’s portfolio, and this is where I think their usefulness, and advantage (much more than the low TER) comes from. Two examples:
- a somewhat lazy investor seeking to invest just in these two funds, but that wishes to have the option of adjusting the weighting between Developed and Emerging Markets according to the economic situation, and moreover thinks he can read the macroeconomic signals in order to boost his returns (no one can consistently).
- an investor setting up a complex portfolio with many funds and wishes to constantly fine-tune his allocation between a wire array of investments, like for example, the S&P 500, Developed Markets, US Small Cap, Emerging Markets, and let’s say UK Medtech Stocks.
Comparative Overview of IB Commissions and Exchange/Transfer Fees, for an investment of 2k CHF
Portfolio 1 VWRD or VWRL:
VWRD can be bought in USD on the LSE (London Stock Exchange) or as an equivalent
VWRL in CHF on SIX (Zurich) or in EUR on AEM (Euronext Amsterdam) for the following fees (I’m converting everything to CHF at the current exchange rate, even though the actual internal IB system might be different):
LSE (for USD denominated securities)
IB commission : 0.05% of trade value, min 1.7 USD
Exchange fee : 0.0045% (0.45 bps) of trade value, min 0.10 GBP
Clearing fee : 0.06 GBP
Currently 2000 CHF = 2056 USD, and -2 USD currency commission = 2054 USD
Fees: 1.7 USD + 0.10 GBP + 0.06 GBP = 1.65 + 0.12 + 0.07 CHF = 1.84 CHF
Zürich (SIX)
IB commission : 0.05% of trade value, min 1.5 CHF
Exchange fee : 0.015% of trade value (min 0.5 CHF) + 1.5 CHF
Clearing fee : 0.38 CHF
Trade Reporting Fee : 1 CHF
*No currency exchange fees.
Fees: 1.5 CHF + 0.5 CHF + 1.5 CHF (all minimum values) + 0.38 CHF + 1 CHF = 4.88 CHF
Euronext (AEB)
IB commission : 0.05% of trade value, min 1.25 EUR
Exchange fee : 0.006% of trade value, min 0.75 EUR
Clearing fee : 0.10 EUR
Currently 2000 CHF = 1936 EUR, and -2 USD currency commission = 1934 EUR
Fees: 1.25 EUR + 0.75 EUR + 0.10 EUR = 2.17 CHF
Conclusion: VWRD. Even when currency exchange commissions are included, the lowest total fees are on LSE ; not by much, but because we are investing in the USD denominated ETF, we have the additional advantage that the earned dividends (that are always in USD) can be invested as soon as they are received without any additional currency exchange expense.
Portfolio 2 VEVE + VFEM:
VEVE and VFEM can equally be bought on SIX in CHF or AEB in EUR, as well as on the LSE but in GBP (where the fees change slightly compared to buying an ETF in USD).
Same results here with lowest fees on the LSE exchange, but with twice the fees every month if one wants to add to both the VEVE and VFEM positions monthly (currency exchange fees for the USD dividends will apply no matter what). Considering monthly contributions the annual costs to buy two funds instead of one is less than 100 USD/CHF a year, so max. 2k over 20 years, not significant.
Any comments and/or corrections are welcome, especially if any of this makes no sense , and maybe this can also help others in my situation.
