There is no universal winner. Buying TSMC gives you a concentrated stake in one Taiwan-based foundry company. Buying a semiconductor ETF gives you a fund interest spread across companies selected by an index and rebalanced under stated rules. The better route depends on how much single-company risk you can accept, the type of semiconductor exposure you want, the ETF’s costs and concentration, your tax and account situation, and your investment horizon.
TSMC’s reported 2025 results were strong, but they do not prove that its shares will outperform a semiconductor ETF. An ETF’s diversification can reduce company-specific risk, but it does not remove semiconductor-cycle, market, geographic, currency, index, liquidity or fund risk.

What you are actually buying
TSMC shares or American depositary shares
Taiwan Semiconductor Manufacturing Company Limited (TSMC) describes itself as a pure-play foundry. It manufactures chips for customers rather than designing, manufacturing or marketing semiconductor products under its own brand. Its ordinary shares trade on the Taiwan Stock Exchange under ticker 2330, while its American depositary shares (ADSs) trade on the New York Stock Exchange under ticker TSM, according to the company’s 2025 annual report and listings information.

A direct purchase therefore gives you an ownership claim on one issuer. Your result depends heavily on TSMC’s earnings, valuation, capital spending, customer demand, execution, regulatory environment, currency movements and the risks associated with its Taiwan operations. Even if the broader chip industry grows, TSMC shares can lag if the company loses market share, faces production problems, spends more than expected or is valued less generously by investors.

A semiconductor ETF
An exchange-traded fund (ETF) share represents a proportional interest in a portfolio. The fund may own chip designers, foundries, equipment manufacturers, memory companies and other businesses connected to semiconductors. Its holdings and weights are determined by the fund’s benchmark methodology, eligibility rules, rebalancing schedule and limits on individual positions.
The VanEck Semiconductor ETF (SMH) illustrates why you must inspect a specific fund rather than treating “semiconductor ETF” as one standardized product. VanEck’s daily holdings page showed TSMC at 9.16% of SMH net assets on September 23, 2026, alongside other semiconductor companies. That percentage is a dated snapshot, not a permanent allocation: market prices, creations and redemptions, index changes and portfolio rebalancing can all alter it.
What TSMC’s latest reported numbers do—and do not—tell you
TSMC’s 2025 annual report reported consolidated revenue of US$122.42 billion, up 35.9% from 2024 in U.S.-dollar terms. Net income was US$55.21 billion, with a 59.9% gross margin and a 50.8% operating margin. These are results for the year ended 2025, not a forecast of your future share return.

In the shareholder letter in that report, Chairman and CEO C.C. Wei said management expected AI-related demand to remain robust entering 2026, while also noting continuing macroeconomic uncertainty. That is management’s outlook, not an independent prediction and not a guarantee that TSMC or a semiconductor ETF will rise.
“Our success is predicated on our steadfast adherence to the pure-play foundry business model.”

The 2025 figures can help you understand the company’s recent scale and profitability. They cannot answer whether TSMC is attractively priced today, whether its growth will continue, or whether a diversified fund would deliver a better risk-adjusted result for you.

Direct TSMC exposure versus an ETF: the central trade-off
| Decision factor | TSMC shares or ADSs | Semiconductor ETF |
|---|---|---|
| Number of issuers | One company | A portfolio of issuers determined by the fund |
| Business exposure | Primarily a contract foundry and related TSMC activities | May include designers, equipment makers, memory companies, foundries and other semiconductor businesses |
| Company-specific risk | High: one company’s execution and finances dominate the result | Spread across holdings, although large positions can still dominate |
| Sector risk | High because TSMC is tied to semiconductor demand | High because the fund is built around the semiconductor sector |
| Geographic and currency exposure | Direct exposure to the issuer’s Taiwan base and the currency of the security you trade | Depends on holdings, fund domicile, listing currency and underlying companies |
| Costs | Trading, account and any applicable conversion costs | Trading costs plus the fund’s recurring expense ratio |
| Control | You choose the position size in one company | The index and fund rules determine holdings and weights |
| Rebalancing | You must sell or buy if you want to change the company exposure | The fund rebalances according to its methodology |
How diversification helps—and where it stops
With TSMC, a single adverse event can affect nearly your entire semiconductor allocation. A manufacturing interruption, customer loss, margin pressure, regulatory change or company-specific legal issue can move the shares even when other chip companies are performing well.

1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesAn ETF distributes exposure among several issuers. Weak results from one holding may have a smaller effect on the fund than they would on that company’s stock. The benefit depends on the actual portfolio, however. A fund with a few very large positions is less diversified than a fund with broader weights, and two funds with the same “semiconductor” label can have materially different concentrations.
Diversification does not make an ETF a broad-market fund. VanEck’s April 30, 2026 SMH fact sheet lists semiconductor-industry, foreign-security, emerging-market, foreign-currency, issuer-specific, index-concentration, market, operational and fund-liquidity risks, among others. It warns that investing involves substantial risk and high volatility, including possible loss of principal. Those disclosures are a reminder that an ETF can reduce single-company exposure without eliminating the possibility of a large sector loss.
Compare the ETF before comparing it with TSMC
The phrase “semiconductor ETF” is not specific enough for an investment decision. Review the fund’s latest prospectus, holdings file and fact sheet, then answer the following questions.
What index does it track?
Read the index description, eligibility requirements and rebalancing schedule. An index may emphasize the largest companies, impose position caps, use equal weighting or apply rules that favor particular business activities. The methodology determines what the fund can own and how quickly its exposure changes.
How concentrated are the largest positions?
Check the current top-10 holdings and each position’s percentage of net assets. A fund can hold many securities while still deriving much of its movement from a handful of large companies. Compare the current weights with the fund’s stated limits rather than assuming every holding is similar in size.
Which countries and currencies are represented?
Look beyond the exchange where the ETF trades. The listing currency is not necessarily the currency of the businesses in the portfolio. Country allocations, foreign securities, emerging-market exposure and currency movements can affect returns independently of the semiconductor cycle.
What does it cost?
The iShares Semiconductor ETF (SOXX) fund page listed a 0.33% expense ratio under its current prospectus at the time of the cited disclosure. Fees can change, so verify the current prospectus before investing. A 0.33% annual expense ratio would amount to approximately US$33 per year on a US$10,000 balance if the balance stayed constant for a full year, before compounding and changes in value. Your brokerage, bid-ask spread, taxes and other account costs are separate.
What risks does the issuer disclose?
Read the prospectus risk section instead of relying on the ETF’s name. In addition to sector volatility, disclosures may cover index concentration, foreign securities, currency, emerging markets, operational events, liquidity and the risks of the individual issuers. A fund can be easier to hold than several individual stocks, but it is not risk-free.
When direct TSMC exposure may fit
Direct shares or ADSs may be a logical choice for an investor who deliberately wants a high-conviction position in TSMC’s foundry business and accepts that one company can dominate the outcome. The approach offers control over position size and does not charge an ETF management fee on the shares themselves, although trading, account, tax and currency costs can still apply.
Before choosing it, consider whether your existing portfolio already has substantial exposure to TSMC through an ETF, technology fund, employer stock or other account. Adding the individual shares may increase concentration more than you realize. Also consider whether you can tolerate a long period in which the company’s share price falls even while its long-term business case remains intact.
When a semiconductor ETF may fit
An ETF may suit an investor who wants semiconductor exposure but does not want to select one winner. The fund handles the portfolio’s scheduled rebalancing, and a weak result from one issuer may be partly offset by results from others. That convenience comes with an expense ratio, rules you do not control and the possibility that the index owns companies you would not have selected yourself.
Rank #4
Review the fund’s concentration before assuming it provides broad diversification. An ETF with a large TSMC allocation can still be meaningfully affected by TSMC-specific news. Conversely, a fund with limited foundry exposure may not behave like a direct TSMC position even if both rise when chip demand is strong.

- Define the exposure you want. Decide whether your objective is a concentrated view of one foundry, diversified exposure to the semiconductor supply chain, or a smaller satellite position around a broader portfolio.
- Check your existing holdings. Add up direct and indirect exposure across taxable accounts, retirement accounts and employer plans. An ETF can already contain TSMC, and several technology funds may own many of the same companies.
- Set a concentration limit. Choose the maximum share of your portfolio you are willing to place in one issuer or one volatile sector. The appropriate limit depends on your finances and risk tolerance; the cited sources do not establish a universal percentage.
- Inspect the ETF documents. Confirm the index, current holdings, position limits, geographic breakdown, currency exposure, expense ratio and risk disclosures using the issuer’s latest prospectus, holdings file and fact sheet.
- Estimate all-in costs. Include the fund expense ratio where applicable, commissions if any, bid-ask spreads, foreign-exchange conversion, account fees and taxes that apply in your jurisdiction.
- Choose the security and listing you can access. TSMC ordinary shares trade as 2330 in Taiwan and ADSs trade as TSM in New York. Your broker’s access, custody arrangements, trading hours and currency handling can differ.
- Write down the reason for owning it. Record the time horizon, intended position size and conditions that would make you reduce or exit the investment. This can help prevent a short-term price move from replacing your original plan.
- Review periodically, not constantly. Recheck holdings, fees and your portfolio weight on a schedule. An ETF’s allocation changes, and a direct position can become oversized after a strong run.
Common mistakes and how to avoid them
Choosing a winner from one strong year
TSMC’s 2025 revenue growth and margins are impressive historical results, but they do not establish future outperformance. A fund may own companies that benefit from different parts of the cycle, and its return will depend on valuation, weights and all holdings—not only on TSMC.
Treating an ETF ticker as a permanent portfolio
The 9.16% SMH allocation to TSMC reported on September 23, 2026 can change. Always date the holdings information you use and verify it again before placing an order.
Assuming diversification removes Taiwan or foreign-market risk
An ETF can still own companies exposed to Taiwan, other foreign markets, emerging markets and currency movements. Read the country and currency breakdown rather than inferring it from the fund’s listing location.
Ignoring valuation
Good businesses can be poor purchases at an excessive price, and a diversified fund can also become expensive. Compare the current price with your own valuation framework; the cited company and fund documents do not provide a forward-return estimate.
Confusing listing currency with investment risk
Buying an ADS in U.S. dollars does not remove the economic exposure created by TSMC’s operations, customers, assets and reporting currencies. Likewise, buying an ETF in your home currency does not eliminate the currencies of its underlying holdings.

- It can be a gift option
- Comes with secure packaging
- Helpful in various ways
Expecting a fund to protect principal
Semiconductor ETFs remain equity investments. The SMH fact sheet specifically warns of high volatility and possible loss of principal. A fund structure changes how exposure is packaged; it does not turn a cyclical sector into a cash substitute.
Taxes, accounts and suitability
Your tax treatment depends on your country, account type, security, holding period and applicable rules. The cited materials do not establish an individual investor’s tax result. Before trading, check how your broker handles foreign securities, ADS fees, dividends, withholding, currency conversion, capital gains and reporting obligations. The same security can have different consequences in a taxable account and a retirement account.
Suitability also depends on factors outside the company and fund documents: your emergency savings, debt, need for near-term cash, time horizon, tolerance for losses and the rest of your portfolio. Neither TSMC nor a semiconductor ETF is automatically appropriate merely because you expect long-term growth in artificial intelligence or computing.

Choose direct TSMC exposure only if you intentionally want one-company concentration and are prepared for company-specific and Taiwan-related risks. Choose a semiconductor ETF if you prefer a rules-based basket and accept fund expenses, index construction, portfolio concentration and sector-wide volatility. If you cannot explain the ETF’s methodology, current top holdings and risks, you do not yet know what you are buying.
The available evidence does not establish that TSMC shares or semiconductor ETFs are generally superior performers. TSMC’s 2025 report describes what happened in 2025 and management’s view as 2026 began; SMH’s 9.16% figure describes one day’s allocation; and SOXX’s 0.33% expense ratio is tied to the cited prospectus disclosure. Refresh those documents and evaluate the choice against your own portfolio before investing.
