VOO Sub-Brokerage 2026 Guide: 5 Steps From Account to First Trade
The most complete VOO sub-brokerage investment guide for 2026. Detailed …
Data as of: VT and VOO holdings are as of 2026-09-30, QQQ holdings as of 2026-10-27 (source: Stock Analysis); VT country weights are Vanguard data as of 2026-08-31. The three funds report on different dates and weights move with prices every day, so check each fund’s official holdings before you buy.
A lot of people buy VT because “I want to own the whole world,” buy QQQ because “I want tech,” and buy VOO because “Buffett said so.”
Sounds like three completely different things.
But line up the top 10 holdings of all three side by side and you get a slightly funny picture: 7 companies show up in all three. NVIDIA, Apple, Microsoft, Amazon, Alphabet, Meta, Micron — full attendance across the board.
So “VT and QQQ are totally different” is only half true. The company names look very similar. What differs are two things: how much money goes into each company, and who gets kicked off the list. This post lays out both.
First, about me. I hold 0050 (Taiwan’s top-50 ETF), the S&P 500, and QQQ.
My reason for QQQ is simple: I’m a believer in tech, but I don’t have the stomach to bet everything on individual stocks, so I use QQQ to buy the whole basket at once. The S&P 500 is America’s 500 largest companies — basically the U.S. version of 0050.
So I’m not surprised at all that the top 10 of those two look alike. But their center of gravity is still different: one is concentrated in tech, the other is spread across the whole U.S. market. What my mix is really missing is the “global” piece.
| Item | VT (Global) | VOO (S&P 500) | QQQ (Nasdaq-100) |
|---|---|---|---|
| Index tracked | FTSE Global All Cap | S&P 500 | Nasdaq-100 |
| Number of holdings | ~10,000 stocks (10,242 line items incl. cash) | ~500 stocks (518 line items) | ~100 stocks (104 line items) |
| Market coverage | 47+ countries, U.S. about 62% | U.S. only | Nasdaq-listed companies only |
| Sector rules | All sectors | All sectors | Excludes financials |
| Top 10 combined | 22.45% | 39.11% | 46.65% |
| Expense ratio | 0.06% | 0.03% | 0.18% |
The key is the last two rows: the further right you go, the more your money is concentrated in a handful of companies.
QQQ’s top 10 take almost half. For every $100 you put in, $47 lands on 10 companies. With VT, the top 10 take only $22 of that $100, and the other $78 is spread across nearly ten thousand companies.
Think of it like a hot pot: all three are the same pot. VT throws in a little of everything, VOO adds more meat, and QQQ is almost all meat — and no seafood (financials).
| Rank | VT | Weight | VOO | Weight | QQQ | Weight |
|---|---|---|---|---|---|---|
| 1 | NVIDIA | 4.54% | NVIDIA | 8.39% | NVIDIA | 8.16% |
| 2 | Apple | 4.11% | Apple | 7.38% | Apple | 7.87% |
| 3 | Microsoft | 3.25% | Microsoft | 5.78% | Microsoft | 6.13% |
| 4 | Amazon | 2.06% | Amazon | 3.71% | Micron | 4.50% |
| 5 | Alphabet A | 1.73% | Alphabet A | 3.07% | Amazon | 4.24% |
| 6 | TSMC | 1.62% | Broadcom | 2.54% | AMD | 3.92% |
| 7 | Broadcom | 1.39% | Alphabet C | 2.45% | Tesla | 3.32% |
| 8 | Meta | 1.36% | Meta | 2.43% | Alphabet A | 2.92% |
| 9 | Alphabet C | 1.36% | Micron | 1.83% | Meta | 2.86% |
| 10 | Micron | 1.02% | Tesla | 1.52% | SpaceX | 2.73% |
| Total | 22.45% | 39.11% | 46.65% |
Alphabet’s A shares and C shares are the same company, so they count as one. Counted that way, the three top 10 lists share 7 companies.
Just look at three things:
1. Same company, almost double the weight. NVIDIA is 4.54% of VT and 8.39% of VOO — 1.85 times as much. In real money: put NT$100,000 in, and about NT$4,540 of it buys NVIDIA in VT, NT$8,390 in VOO, and NT$8,160 in QQQ.
2. VT’s top 10 includes a name every Taiwanese investor knows. TSMC ranks 6th in VT, ahead of Broadcom and Meta. Neither VOO nor QQQ has it in the top 10 — the next section explains why.
3. QQQ has the strongest semiconductor flavor. Micron is 4th and AMD is 6th. In VOO they rank 9th and 11th; in VT only 10th and 12th. QQQ’s tech weighting is over half, and this table shows it.
The S&P 500 only takes U.S. companies, so VOO has no TSMC, no Samsung, and no ASML.
VT holds roughly 9,500 stocks that VOO doesn’t — mostly non-U.S. companies plus small and mid caps. The non-U.S. companies that make VT’s top 25:
| Company | Market | VT weight | VT rank |
|---|---|---|---|
| TSMC | Taiwan | 1.62% | 6th |
| Samsung Electronics | South Korea | 0.77% | 14th |
| SK hynix | South Korea | 0.63% | 17th |
| ASML | Netherlands | 0.59% | 18th |
QQQ is a special case: it takes companies “listed on Nasdaq,” whether or not they are American. So foreign companies listed on Nasdaq, like ASML and ARM, are in QQQ — but TSMC’s American depositary receipts trade on the New York Stock Exchange, so QQQ doesn’t have it.
This matters for Taiwanese investors: if you already own 0050, TSMC is already more than half of it (details in 0050 TSMC weight and concentration risk). Add VT and your TSMC exposure stacks up a bit more; add VOO or QQQ and it doesn’t change at all.
This is the part most people miss.
The Nasdaq-100’s rules are Nasdaq-listed companies only, and no financials. The result is a whole group of American blue chips that QQQ holds none of:
| Company | Sector | VT | VOO | QQQ |
|---|---|---|---|---|
| Berkshire Hathaway (BRK.B) | Financials | 0.70% | 1.41% | — |
| Eli Lilly (LLY) | Health care | 0.79% | 1.41% | — |
| JPMorgan Chase (JPM) | Financials | 0.75% | 1.34% | — |
| ExxonMobil (XOM) | Energy | 0.57% | 1.02% | — |
| Johnson & Johnson (JNJ) | Health care | 0.54% | 0.97% | — |
| Visa (V) | Financials | 0.52% | 0.91% | — |
| AbbVie (ABBV) | Health care | 0.40% | 0.70% | — |
| Mastercard (MA) | Financials | Not in top 25 | 0.68% | — |
That’s right: buying QQQ means not buying Buffett’s company. Plenty of people say “I trust Buffett” while going heavy on QQQ — those two things actually contradict each other.
That doesn’t make QQQ bad. In years when tech rallies, leaving out banks, drug makers, and oil lets it run faster. But when tech pulls back, QQQ has none of those “slowpokes” to cushion the fall. For long-term returns and drawdowns of QQQ vs the S&P 500, see VOO, QQQ, VT fees and performance compared.
On the flip side, a few stocks are QQQ favorites: after Walmart moved its listing to Nasdaq, it ranks 13th in QQQ (2.49%) but is only 0.70% of VOO.
The newest example is SpaceX. It only went public in June 2026, and in July it entered the Nasdaq-100 under Nasdaq’s new fast-entry rule. It is now QQQ’s 10th-largest holding (2.73%). The S&P 500 didn’t change its rules — a company has to be listed for 12 months before it is even considered — so VOO doesn’t hold it yet. Whether a company gets into your ETF depends on the index rules, not on how big the company is.
| Sector (GICS) | VT | VOO | QQQ |
|---|---|---|---|
| Information technology | 28.1% | 37.84% | Over half |
| Financials | 16.79% | 12.24% | Almost 0 |
| Industrials | 11.6% | 8.37% | Lower |
| Materials | 3.95% | 1.83% | Lower |
QQQ’s sector weights vary a lot by data provider (GICS and ICB classifications give very different numbers), so this table only shows the direction for QQQ, not exact figures.
Because VT includes big banks and industrial companies from Europe, Japan, and Canada (HSBC, Royal Bank of Canada, Mitsubishi UFJ, Siemens), its financials and industrials weights are clearly higher than the U.S. market’s. That’s where VT’s “less techy” feel comes from: it isn’t deliberately buying less tech — the world economy just isn’t only tech.
The table below combines each fund’s top 25, 31 stocks in total. — means the ETF doesn’t hold it; “Not in top 25” means it isn’t in that ETF’s top 25 (VT holds nearly ten thousand U.S. and global stocks, so it owns basically every large U.S. company).

| CSCO | Cisco | Not in top 25 | 0.64% | 1.88% | QQQ #17 |
| LRCX | Lam Research | Not in top 25 | 0.62% | 1.29% | QQQ #20 |

| COST | Costco | Not in top 25 | Not in top 25 | 1.89% | QQQ #16 |
QQQ’s top 25 also includes Palo Alto Networks, Texas Instruments, CrowdStrike, Netflix, Amgen, and Linde, which aren’t in the table above — each weighted between 1.0% and 1.4%. Full lists are at Stock Analysis for QQQ holdings, VOO holdings, and VT holdings.
Once you’ve looked at the holdings, the relationship is clear: VT contains VOO, and VOO largely overlaps with QQQ.
So holding both VOO and QQQ isn’t diversification — it’s “buying the same tech giants twice.” Holding both VT and VOO means adding extra U.S. weight on top of a global portfolio.
You might ask: you don’t own VT yourself, so why tell beginners to buy it?
Because a beginner’s biggest enemy isn’t returns — it’s volatility. Panic at your first big drop, stop your auto-investing, sell everything, and no investment will help you after that. To build the habit of “keep buying,” start practicing with the most diversified, least bumpy option, and once you’re sure you can take the swings, move on to other choices. VT is the practice field, not the finish line.
So my suggested order: if you only want one fund, start with VT; if you want more U.S. weight, add VOO; and only consider QQQ once you’re sure you can handle big drawdowns and want more tech. I don’t recommend beginners jump straight into it.
If you do buy QQQ, remember it has no financials and no Buffett. Without those slowpokes at the bottom, your portfolio will definitely swing more. Besides a strong stomach, the money you put in has to be truly “useless” — real spare cash. Otherwise, if it drops right when you need the money, you’re forced to sell at the bottom, your principal shrinks, and recovering takes even longer. Buying VT from Taiwan through sub-brokerage (複委託) means a 30% dividend withholding tax. If you don’t want to open a sub-brokerage account, Taiwan also lists a “Taiwan version of VT” (009826); for how the taxes and fees compare, see VT vs VWRA sub-brokerage tax and fee calculator.
Weights move with stock prices every day and indexes rebalance regularly, so always go by each fund’s latest official holdings.

Before you buy an ETF, spend three minutes on its top 10 holdings and you’ll have a much clearer idea of what you’re betting on. That’s it.
