How to build Warren Buffett's 90/10 asset allocation with ASX ETFs

Buying shares in ASX ETFs can be a great way to get your portfolio started.

If you're just getting started out with investing and you don't have a lot of money behind you, buying shares in ASX ETFs can be a great way to get your portfolio started.

Not only is it a straightforward process, but one of the best things about investing in an ETF is the broad exposure you can get to different parts of the market without investing in several companies yourself.

And with many of the world's investment elite saying ETFs are a great way to build wealth, it's something that I'll be focused on myself in the following years.

What is Warren Buffett's 90/10 asset allocation?

You may recall Warren Buffett's 90/10 portfolio asset allocation for retirement investing. He says to invest 90% of your money into a low-fee stock index fund and 10% into short-term treasuries.

The focus with the 90/10 asset allocation is having exposure to the stock market while hedging any downside risk with short-term treasuries.

How can you build Warren Buffett's 90/10 asset allocation with ASX ETFs?

You can build your own 90/10 asset allocation using ASX ETFs that give you exposure to the ASX200 and Australian Government Bonds.

The Vanguard Australian Share ETF (ASX: VAS) tracks the performance of the ASX 200. With this ETF you get exposure to Australia's biggest companies like BHP Group Ltd (ASX: BHP), Wesfarmers Ltd (ASX: WES) and the Commonwealth Bank of Australia (ASX: CBA) without needing to buy individual shares in each company. This fund charges a 0.14% management fee.

For exposure to Australian Government Bonds, you could buy shares in the SPDR S&P/ASX Australian Government Bond Fund (ASX: GOVT). It tracks the S&P/ASX Government Bond Index, and it can help you hedge against potential market downturns. The fund charges a management fee of 0.22% and has a current yield of 3.47%.

But, what if you still want to pick your own stocks?

When you have a keen interest in finance and investing, the thought of buying shares in an ASX 200 ETF and Australian Government Bonds ETF could make you feel like you're missing out on picking stocks yourself. You can have the best of both worlds, though.

If you still want to pick your own stocks while building wealth through an ASX 200 ETF, decide on what proportion of your portfolio you want to set aside for picking your own investments. For example, if you have a lower risk appetite like me you may decide on an 80/10/10 split between an ASX 200 ETF, a short-term treasuries ETF and 10% for your own stock picks.

Leaving aside part of your asset allocation for making your own stock picks will give you exposure to the broader market with an ETF while giving you ownership over building out your own stock portfolio. With this approach you can invest like Warren Buffett would while still having some personalised decisions to make up your portfolio.
