He points to Vanguard Information Technology ETF (VGT) as one way to get that exposure. That is an attributed investment opinion—not evidence that technology is the best first investment for every beginner. A sector ETF is narrower than a broad-market fund, and its concentration can mean greater share-price volatility.
What the recommendation is—and what it is not
In his October 5, 2026 article, Marc Guberti favors the information technology sector for a new investor and identifies AI-related hardware, software, and data-center businesses as the motivating theme. He names Vanguard Information Technology ETF (VGT) as an ETF example.
The useful distinction is between considering technology as an allocation and treating it as a complete beginner’s portfolio. VGT is a sector fund, not a broad-market index fund: it focuses on one area of the stock market. Vanguard cautions that funds focused on a relatively narrow market sector face higher share-price volatility risk. A strong recent theme does not remove the possibility of losses or establish that the same sector will lead in the future.
How VGT differs from a broad-market index fund
A broad-market fund is designed to represent a wider range of companies and sectors; a technology-sector ETF concentrates exposure in information technology. The choice is therefore not simply “index funds versus stocks.” A sector ETF can itself track an index, but the index and holdings are limited to a narrower slice of the market.
#1 Best Overall
| Consideration | Broad-market index fund | VGT, a technology-sector ETF |
|---|---|---|
| Exposure | A wider market range, potentially including multiple sectors; exact breadth depends on the fund and benchmark. | Information technology stocks, as classified by Vanguard. |
| Concentration | Generally broader across sectors, though the actual mix depends on the index. | Concentrated in one sector, so technology-specific developments can have a larger effect. |
| Expense ratio | Varies by fund; check its current prospectus or listing. | 0.09%, according to Vanguard’s VGT listing accessed October 7, 2026. Fund costs and published figures can change. |
| Holdings and benchmark | Depend on the specific fund and the index it tracks. | Check Vanguard’s current fund listing for holdings and benchmark details. |
| Historical performance | Must be compared with a sector fund over the same dates and using the same return convention. | Past returns are not a forecast; compare dated figures rather than mismatched time windows. |
Vanguard describes VGT as a stock-sector information technology ETF and lists its expense ratio as 0.09% on its ETF listing, accessed October 7, 2026. An expense ratio is an ongoing fund operating expense expressed as a percentage of assets; it is not the only possible cost of investing. Review the fund’s current materials and your brokerage’s fee schedule before buying.
Why the AI case should not decide the whole portfolio
Guberti’s argument links technology’s appeal to the businesses supplying AI computing infrastructure and related software. That can explain why an investor might want exposure to the theme, but it does not establish that a technology ETF is diversified enough to serve as a portfolio’s only holding or that AI-related companies will keep outperforming.
Rank #2
The article also reports a 15.3% annualized S&P 500 return over the past decade, says nine of the ten best-performing S&P 500 stocks were tied to the AI build-out, and cites 106% year-over-year Nvidia sales growth in fiscal 2027 Q2. Those are claims in the Motley Fool article, not independently verified figures here. Its available extract does not establish the exact return measurement end date or the ranking period and methodology for the stock claim, and the Nvidia fiscal-period figure should be checked against the company’s earnings release before relying on it. Even a correctly measured historical result would describe a past period, not guarantee future performance.
How to decide whether a sector ETF belongs in your plan
- Decide on the role first. Ask whether you want broad-market exposure as a core holding or a narrower technology allocation. A sector fund’s focus makes it a different choice from a diversified market-wide fund.
- Inspect the actual fund. Use Vanguard’s VGT listing to review its current holdings, benchmark information, performance dates, and expense ratio. Do not assume a ticker’s sector label tells you the full portfolio composition.
- Compare like with like. Put VGT beside the specific broad-market fund you are considering. Compare the same measurement dates and return convention, along with holdings, benchmark, expense ratio, and any account or trading costs.
- Consider concentration risk. Vanguard’s explanation of sector and specialty funds notes the higher share-price volatility risk associated with relatively narrow sectors. Diversification cannot guarantee a profit or prevent a loss, but it can avoid depending on a single industry’s fortunes.
- Fit the investment to your circumstances. Your time horizon, ability to tolerate losses, other investments, and need for diversification matter. The article’s preference is not individualized financial advice or a guarantee of results.
So, should a new investor buy VGT?
VGT is a concrete way to consider information-technology exposure, and Vanguard’s listing reports a 0.09% expense ratio as of October 7, 2026. Whether it is appropriate depends on the investor’s overall plan and comfort with a concentrated sector fund. Guberti’s case is best read as a thesis for a technology allocation—not a universal instruction to replace a broad-market foundation with one sector.
