VOO Sub-Brokerage 2026 Guide: 5 Steps From Account to First Trade

Introduction: Is Investing Difficult? Maybe Being “Lazy” Is Better

Many people think that investing and financial management is a profound subject, full of complex charts and terms that make people daunting. But to be honest, if you want to grow your wealth steadily through investment, you don’t have to stare at the market every day and study financial reports.

Sometimes, being “lazy” is the most efficient strategy.

In this article, I will share my personal experience and take you from scratch, step by step, to complete the “sub-brokerage” account opening at a Taiwanese brokerage, and buy your first US stock ETF - VOO. This is the starting point that I think is most suitable for beginners, so that your wealth path can start steadily in the most worry-free way. 🚀

Why Did I Choose VOO Later?

VOO (Vanguard S&P 500 ETF) is an ETF that tracks the US S&P 500 index. Simply put, buying one share of VOO is equivalent to buying stocks of the top 500 US companies at once, including tech giants such as Apple, Microsoft, NVIDIA, Amazon, and Google. VOO is one of the most popular US stock ETFs in the world and is also Buffett’s preferred choice for general investors.

If you are not very clear about the differences between popular ETFs such as VOO, QQQ, and VT, it is recommended to read this article first: VOO、QQQ、VT怎麼選？10大熱門ETF投資指南, after understanding the characteristics of different ETFs, you will be clearer about why VOO is suitable for most investors.

Honestly, I initially invested in the more volatile QQQ (Nasdaq 100 Index ETF). But as I became clearer about my financial goals, I found that VOO was more in line with the needs of long-term investment - pursuing stable annualized returns rather than short-term high volatility. VOO’s annualized rate of return has historically averaged around 10-12%, which is a very suitable target for long-term holding.

The Four Major Investment Advantages of VOO ETF:

• ✅ Diversified Enough: Investing in 500 leading companies at a time, putting eggs in many good baskets, naturally reduces risk.

• ✅ Low Cost: The expense ratio is only 0.03%, which means that for every NT$10,000 (USD $300) invested, only NT$3 (USD $0.1) of management fee is charged per year, which is extremely low cost.

• ✅ Stable Performance: In the long run, the annualized rate of return of the S&P 500 index is about 10-12%, which is a very reliable performance indicator.

• ✅ Easy to Buy and Sell: The trading volume is very large, you can buy it whenever you want, and you can sell it whenever you want.

Sub-brokerage vs. Overseas Brokerage? I’m “Too Lazy” to Choose Sub-brokerage

Before buying US stocks, the biggest entanglement point for novices must be: “Should I use an overseas brokerage or a sub-brokerage?”

The Internet is full of comparisons about handling fees, and many people will say that overseas brokerages have lower handling fees. Yes, that’s true. But after a round of research, I finally chose sub-brokerage because of “laziness” and a more important consideration.
