The biggest flaw I see is using a retirement portfolio when you should be accumulating. If you're far from retirement, then you might want 90% stocks. But even if you plan to retire in 2030, you'd want a lower bond allocation. Here's the allocation used by both Vanguard Target Retirement 2030 and Schwab Target 2030:
70% stocks
30% bonds

So I'd suggest 70% stocks if you plan to begin withdrawing money in 2030, and a higher allocation if you plan to let those assets grow until a later retirement date. When you hit a correction, your portfolio isn't supposed to have lower volatility - it's supposed to take a massive drop... and then you make contributions which greatly improve things. Your protection against crashes is your income, your salary.
Same goes with gold. If you want a permanent portfolio, you don't need it before retirement. Any correction is an opportunity to buy more shares. You can ease into your gold allocation as you need it - as you approach retirement.
You can also look at Vanguard Total World to see that U.S. equities are roughly 55% of the world (by market cap), so a 50/50 split between U.S. and international is actually quite reasonable for a foreign investor. If you can get a "total U.S. stock market" fund or ETF, even better (VTI, SCHB, ITOT are examples that trade on exchanges, that you might be able to purchase through Interactive Brokers).
Thanks MustacheAndaHalf,
Really appreciate your view/input on this.
You are right on the growth/accumulation phase - but my current 37.5% allocation to bonds + 7.5% gold = total of 45% weight reflects my low-medium risk tolerance.
Moreover, job stability is an issue, i.e. in times of distress things may go south and I may end up either with a much lower salary or even jobless (this is another fear I am facing) so I cannot make new contributions to the portfolio and hence miss buying opportunities when market crashes.
So, by assimilating the 20% allocation on EM bonds to equities-like assets, actually my AA embeds 75% risky assets (i.e. 25% S&P, 500, 10% Developed Europe & UK, 10% Emerging markets equities, 10% REITs, 20% EM bonds). The remaining 25% (17.5 % US treasuries +7.5% gold) is my hedge.
As an European we cannot purchase US based index funds but need to go with UCITS versions (Irelnad based funds). Nevertheless, there is a Vanguard total stock market index available which I can buy, however, I prefer to stay away from Japan/other Pacific countries. Additionally, I expect US weight in global indexes to drop in the following years due to emerging China. My AA on equities does not include Japan and includes a higher weight on China - 5% (compared with global index weights)- part of my current bets.
I admit my portfolio construction has lots of biases or "bets against current market weights" (look at China weight, avoidance of Japan), low US bonds weight, gold weight, overweight of REITs, but all is in light of recent global trends and reflect my judgement.
Really appreciate your input and I hope you are not offended by my arguments to deter/debate your advice :)
