Quick Answer
- QQQ and QQQM are identical portfolios. Buy QQQM unless you trade options on QQQ or need institutional liquidity.
- VGT is the pure tech sector fund: 350+ companies, all classified as IT by GICS. Amazon, Alphabet, and Netflix are not in VGT.
- XLK is the S&P 500 tech slice: 60-70 companies, lowest cost at 0.09%, but Apple and Microsoft often exceed 40% combined.
- None of these funds are diversified. All are deliberate bets on technology outperforming the broader market.
- For a buy-and-hold investor who wants the Nasdaq-100 bet, QQQM at 0.15% is the right vehicle. QQQ at 0.20% is for traders.
QQQ vs QQQM: Same Fund, Different Price Tag
Invesco launched QQQM in October 2020 as a lower-cost version of QQQ specifically for retail buy-and-hold investors. Both funds track the Nasdaq-100 Index. Both hold the same 101 companies. The difference is purely structural.
If you are not actively trading QQQ options or executing institutional block trades, use QQQM. You save 5 basis points per year for identical exposure. On $100,000, that is $50 per year with no difference in returns.
QQQ charges 0.20% and has $313B in assets, making it one of the most liquid securities in the world. That liquidity is why institutions and options traders use it: the bid-ask spread is essentially zero and options volume is enormous. For long-term investors holding shares, none of that matters.
QQQM charges 0.15%, has roughly $50B in assets, and offers the same daily liquidity retail investors need. Schwab, Fidelity, and Vanguard platforms all support QQQM at full functionality. There is no practical reason for a buy-and-hold investor to pay the QQQ premium.
Same 101-stock Nasdaq-100 portfolio as QQQ, at 0.15% instead of 0.20%. Designed for retail buy-and-hold investors. If you are holding shares in a brokerage or IRA and not trading options, use this one.
The most-traded ETF in the world by dollar volume. Use QQQ if you are actively trading options on the Nasdaq-100 or need institutional liquidity for large block trades. For everything else, QQQM is cheaper.
VGT: The Pure Technology Sector Fund
VGT (Vanguard Information Technology ETF) tracks the MSCI US Investable Market Information Technology 25/50 Index. That name matters: it only holds companies classified as Information Technology under the Global Industry Classification Standard (GICS).
This is the key difference between VGT and QQQ. Amazon is classified as Consumer Discretionary. Alphabet and Meta are Communication Services. Netflix is Consumer Discretionary. Tesla is Consumer Discretionary. None of them are in VGT. All of them are in QQQ.
VGT holds companies that are definitionally tech: software developers, semiconductor makers, IT services firms, hardware manufacturers. Apple, Microsoft, and Nvidia dominate both VGT and QQQ. But VGT's exposure below the top three is meaningfully different, tilting more toward pure-play software and semiconductor names rather than e-commerce and social media.
Pure tech sector fund by GICS classification. Amazon, Alphabet, Netflix, and Tesla are not in VGT. If your thesis is strictly on software, semiconductors, and IT services, VGT delivers that without the consumer and communication services exposure in QQQ.
Apple and Microsoft together make up roughly 40-45% of VGT. Adding Nvidia takes the top three to approximately 55%. VGT is a concentrated fund even with 320 holdings because the index weights by market cap and the largest tech companies are enormous.
XLK: The S&P 500 Technology Slice
XLK (Technology Select Sector SPDR Fund) tracks the Technology Select Sector Index, which holds only the technology companies in the S&P 500. That means two constraints: the company must be in the S&P 500, and it must be classified as Information Technology under GICS.
XLK has the lowest expense ratio of the four at 0.09%, a 20-year track record, and a straightforward mandate. It is also the most concentrated: roughly 60-70 holdings, with Apple and Microsoft historically comprising 40-45% of the fund combined because the index weights them by their full market capitalization.
The S&P 500 constraint means XLK excludes smaller tech companies that appear in VGT. It is a large-cap-only tech bet. The low cost and long track record make it appealing, but the Apple/Microsoft concentration is the largest single-name risk of any of the four funds discussed here.
The cheapest of the four at 0.09%. Holds only S&P 500 tech companies. Apple and Microsoft typically exceed 40% combined. Strong long-term track record. The right choice if you want the S&P 500 tech slice at minimum cost and can tolerate the Apple/Microsoft concentration.
Side-by-Side Comparison
| Fund | Expense Ratio | Holdings | Index | Amazon/Alphabet in fund? | AUM |
|---|---|---|---|---|---|
| QQQ | 0.20% | 101 | Nasdaq-100 | Yes | ~$313B |
| QQQM | 0.15% | 101 | Nasdaq-100 (identical) | Yes | ~$50B |
| VGT | 0.10% | ~320 | MSCI US IMI IT | No | ~$80B |
| XLK | 0.09% | ~65 | S&P 500 IT Sector | No | ~$75B |

Which Tech ETF Should You Buy
The answer depends on what you are actually trying to do.
Buy QQQM if:
- You want the Nasdaq-100 large-cap growth exposure
- You want Amazon, Alphabet, and Meta as part of the fund
- You are a buy-and-hold investor and not trading QQQ options
- You want one fund that captures most of the mega-cap tech story
Buy VGT if:
- You want pure IT sector exposure without e-commerce and social media
- Your thesis is specifically on software, semiconductors, and IT services
- You hold a total market or S&P 500 fund and want to tilt toward IT specifically
- You want more mid-cap tech companies alongside the large-cap names
Buy XLK if:
- You want the lowest-cost tech sector option (0.09%)
- You are comfortable with very high Apple and Microsoft concentration
- You want S&P 500 tech only, no smaller tech companies
- You already hold another S&P 500 fund and want to overweight its tech component
BFF Take
For most investors making a deliberate tech sector bet, QQQM is the clearest choice. The Nasdaq-100 captures large-cap tech and growth without requiring you to decide exactly how to define "technology." VGT is the better choice for investors with a specific IT sector view who want Amazon and Alphabet excluded. XLK is the most concentrated and cheapest, which makes it right for a very specific investor: someone in a taxable account who wants maximum cost efficiency and understands the Apple/Microsoft weight. None of these are substitutes for broad market exposure. They are sector tilts. Use them as additions to a core position, not as replacements for one.
Holdings Overlap: What They Share and What They Don't
Apple, Microsoft, and Nvidia are the three largest positions in all four funds. The overlap at the top is high. The divergence comes in positions 4 through 101.
QQQ and QQQM are identical, so overlap between them is 100%. VGT overlaps with QQQ/QQQM significantly in the pure tech names but excludes Amazon (15th largest in QQQ), Alphabet (ranked 4th and 6th in QQQ as two share classes), and Meta (7th). XLK overlaps with VGT heavily at the top but excludes all mid-cap tech companies that appear in VGT's 320 holdings.
Holding QQQ or QQQM alongside VGT does not diversify you further in tech. It slightly reduces your Amazon, Alphabet, and Meta exposure while increasing your pure-IT weighting. Holding all four funds primarily creates unnecessary complexity at minimal diversification benefit.
Frequently Asked Questions
For most buy-and-hold investors, QQQM is the best tech ETF. It holds the 101 largest non-financial Nasdaq companies at 0.15%, including Apple, Microsoft, Nvidia, Amazon, and Alphabet. It is identical to QQQ in holdings but costs 5 basis points less per year. VGT is the better choice for investors who want pure technology sector exposure without consumer discretionary or communication services companies. XLK is the most concentrated and cheapest at 0.09%, suitable for investors focused on S&P 500 tech names only. Past performance does not guarantee future results.
QQQ and QQQM hold identical portfolios: the 101 largest non-financial companies listed on the Nasdaq exchange. The only difference is cost and investor type. QQQ charges 0.20% and was designed for institutional investors and active traders who value extreme liquidity and options market depth. QQQM charges 0.15% and was designed for retail buy-and-hold investors. If you are not actively trading options on QQQ or executing large institutional block trades, QQQM saves you 5 basis points per year for the exact same exposure.
It depends on what you want. VGT tracks the MSCI US Investable Market Information Technology index, which includes only technology sector companies as classified by GICS: software, hardware, semiconductors, IT services. QQQ is not a tech fund strictly speaking. It is a Nasdaq index fund that happens to be heavily tech-weighted (around 60%) but also includes Amazon, Alphabet, Netflix, and Tesla, classified as consumer discretionary and communication services. VGT gives you purer tech sector exposure. QQQ gives you the Nasdaq-100, a broader large-cap growth bet. Both have strong long-term track records. The choice depends on your specific thesis. Past performance does not guarantee future results.
XLK is more concentrated than QQQ. XLK holds only the technology companies in the S&P 500, typically around 65 stocks with Apple and Microsoft often making up 40% of the fund combined. QQQ holds 101 Nasdaq companies with more diversification across tech, consumer, and communication names. XLK charges 0.09%, which is cheaper than QQQ's 0.20%. For pure S&P 500 tech sector exposure at low cost, XLK. For the broader Nasdaq-100 large-cap growth exposure including Amazon and Alphabet, QQQ or QQQM.
You can, but it adds complexity without much diversification benefit. Both are heavily concentrated in Apple, Microsoft, and Nvidia. Holding both mainly reduces your Amazon and Alphabet weighting while increasing pure-IT sector concentration. Most investors are better served picking one fund that matches their thesis and holding that rather than blending two funds that share their largest positions.
