Local ETFs vs. Buying US Stocks Directly: Which Strategy Actually Wins?

Here’s a question that comes up constantly in investing forums, WhatsApp group chats, and Reddit threads: Should I just buy a local ETF that tracks the S&P 500, or should I open a brokerage account and buy US stocks directly? It sounds simple. It isn’t. The answer depends on a web of factors — taxes, costs, currency, convenience, and your own investing temperament — that most quick-answer posts completely gloss over.

This article is going to change that. We’re going to get into the actual numbers, the real trade-offs, and give you a clear framework for making the decision that fits your situation. Whether you’re a Singaporean investor looking at platforms like Moomoo to access Wall Street, or a global retail investor trying to figure out if iShares is doing the heavy lifting better than you ever could, this breakdown is for you.

The original insight we’ll defend throughout: for most retail investors, the “just buy direct” instinct is overrated, but the “just use a local ETF” reflex is undercosted. The truth lies in a hybrid approach that most people never bother to build — and the devil is entirely in the details.

Background & Context: Why This Question Is Hotter Than Ever in 2026

The global retail investing boom that started during the pandemic years never fully cooled. If anything, it evolved. Platforms like Moomoo, Tiger Brokers, and Interactive Brokers have made it genuinely easy for investors in Singapore, Australia, and across Southeast Asia to buy individual US stocks — Apple, Nvidia, Tesla — as simply as ordering a meal online. Meanwhile, local exchanges in Singapore (SGX), Hong Kong (HKEX), and elsewhere have expanded their ETF offerings dramatically, listing Ireland-domiciled funds, UCITS-compliant products, and accumulating share classes that previously required a specialist broker to access.

At the same time, the stakes have risen. As of mid-2026, US equity markets remain the dominant destination for global capital. The S&P 500 has continued to be the benchmark everyone measures themselves against, and technology stocks — particularly AI-adjacent names — have driven outsized returns that make “just buying the index” feel almost too conservative to some investors.

Then there’s the geopolitical backdrop. The cross-listing of major Asian tech companies on US exchanges — Barron’s recently covered SK Hynix’s US listing and what it signals about market integration — means the line between “local” and “American” investing is blurring at the corporate level too. You can now, in theory, buy a Korean memory chip giant on a US exchange, a US tech ETF on the SGX, or the underlying US stocks directly through a Singapore-based brokerage. The optionality is dizzying.

Fidelity Investments, one of the largest brokerages in the world, outlines multiple pathways for international investors to access US stocks — from American Depositary Receipts (ADRs) to direct foreign stock trading — which underscores that the infrastructure for going “direct” has never been more accessible. But accessible doesn’t mean optimal.

Section 1: The Real Cost Comparison — It’s Not Just the Brokerage Fee

Most investors anchor on the most visible cost: the trading commission. That’s a mistake. Here’s the full cost picture you need to consider:

Costs of Buying US Stocks Directly

• Brokerage commissions: Many platforms (Moomoo, Webull, IBKR Lite) now offer zero or near-zero commissions on US stocks. This is largely a non-issue in 2026 for major US-listed equities.
• Currency conversion (FX spread): This is the hidden killer. If you’re buying in USD from a SGD account, the FX spread on most retail platforms runs between 0.3% and 1.5% per transaction. Round-trip (buy then sell), that’s potentially 3% of your capital eroded before the market moves a cent.
• US Withholding Tax on Dividends: This is the big one. The US levies a 30% withholding tax on dividends paid to non-resident foreign investors. Some countries have tax treaties that reduce this (e.g., UK residents pay 15%), but Singapore has no such treaty — meaning Singaporean investors holding US stocks directly lose 30 cents of every dollar in dividends to the IRS before they even see it.
• US Estate Tax exposure: Foreign nationals holding US-listed securities directly are subject to US estate tax on assets above $60,000 USD at death. This is not theoretical — it’s a real liability that is almost universally ignored by retail investors until it’s too late.
• Platform fees and custody charges: Some brokerages charge inactivity fees or custody fees for holding foreign securities. Always read the fine print.

Costs of Buying a Local ETF Tracking US Indices

• Expense Ratio (TER): This is the ongoing annual cost embedded in the fund. For example, the Vanguard S&P 500 UCITS ETF (VUSA) listed on the London Stock Exchange (and accessible via many Singapore brokerages) has a TER of just 0.07% per year. The iShares Core S&P 500 UCITS ETF (CSPX) comes in at 0.07% as well. These are razor-thin.
• Bid-ask spread: ETFs trade on exchange and have a spread between buy and sell price. For liquid ETFs, this is typically 0.01%–0.05%, negligible.
• Currency class risk: Many SGX-listed ETFs are priced in USD, SGD-hedged variants, or other currencies. Choosing the wrong share class can introduce costs or complexity.
• Withholding tax (fund level): This is where the domicile of the ETF matters enormously. An Ireland-domiciled ETF holding US stocks benefits from the US-Ireland tax treaty, reducing the withholding tax on US dividends from 30% to 15%. This alone can be worth 0.5%–1.0% of annual return for dividend-paying indices. An accumulating (not distributing) share class reinvests dividends internally and can further defer or eliminate the investor-level dividend tax event.

The Cost Comparison Table

The verdict on costs: For a dividend-yielding portfolio, an Ireland-domiciled accumulating ETF held by a non-US retail investor will almost always be more tax-efficient than holding US stocks directly. The 15% treaty advantage on dividends, combined with zero estate tax exposure, is a structural advantage that a 0.07% TER doesn’t come close to erasing.

Section 2: Control, Customisation, and the Alpha Question

Here’s where the “buy direct” camp makes its strongest argument — and it’s a fair one. When you buy a local ETF, you get what you get. If the S&P 500 ETF includes companies you find ethically objectionable, or sectors you think are overvalued, you can’t surgically remove them. You’re along for the full ride.

The Case for Direct Ownership

Buying US stocks directly gives you:

• Concentration where you have conviction: If you believe Nvidia’s AI dominance is a decade-long story, you can size that position at 20% of your portfolio. An S&P 500 ETF might have Nvidia at 6–7%. You’re capped by the index weight.
• Tax-loss harvesting: In jurisdictions where capital gains tax applies, you can sell losing individual positions to offset gains — a strategy that’s impossible inside an ETF wrapper.
• Dividend timing control: You decide when to reinvest dividends and can manage the timing for tax purposes.
• Access to single-stock events: IPOs, rights issues, tender offers, and spinoffs — direct shareholders participate in these directly.
• Voting rights: You own actual shares. You vote on corporate governance matters. In practice, most retail investors ignore this, but it exists.

The Reality Check on Alpha

Here’s the uncomfortable truth: the data on retail investor stock-picking is brutal. Study after study — from Dalbar’s QAIB reports to academic analyses of retail brokerage data — shows that the average individual investor underperforms the S&P 500 over any rolling 10-year period. Not slightly. Meaningfully. The gap is often 2–4% annually, driven by poor timing, overtrading, and emotional decision-making.

That doesn’t mean you can’t outperform. It means you should have a very specific, defensible reason why you think you will. “I follow tech news closely” is not that reason. Having a genuine information edge, a disciplined valuation framework, or asymmetric access to emerging trends — those are reasons.

The TechStock² live market updates format — real-time price moves, analyst commentary, earnings surprises — can feed the illusion of being “in the know.” In reality, that information is priced in microseconds after it’s available. Reacting to intraday news as a retail investor is almost always a net negative.

The Hybrid Direct Approach: Direct Indexing

There’s a middle ground that’s gaining traction in 2026: direct indexing. Platforms now allow you to buy every stock in the S&P 500 individually (or a representative subset), giving you index-like diversification with individual stock ownership benefits — principally tax-loss harvesting. This requires significant capital (typically $100,000+ USD to make it practical) and a platform that supports it. Fidelity and Schwab have both been expanding direct indexing products. For most retail investors, this is still out of reach, but it’s worth knowing it exists.

Section 3: Practical Access, Platform Reality, and Behavioural Factors

Theory is one thing. What actually happens when a Singaporean investor sits down and tries to implement either strategy?

Buying US Stocks Directly from Singapore in 2026

According to Moomoo’s 2026 guide for Singaporean investors, the process of buying US stocks directly has genuinely simplified. Here’s the rough step-by-step:

1. Choose a brokerage: Options include Moomoo SG, Tiger Brokers, Interactive Brokers, Saxo Bank, and Standard Chartered Online Trading. Each has different fee structures, FX rates, and platform quality.
2. Open and fund the account: Standard KYC process, usually 1–3 business days. Fund in SGD, convert to USD (watch the FX spread).
3. Place your order: Market, limit, or stop orders are all available. Most platforms show live US market data during Singapore evening hours (US markets open 9:30 PM SGT).
4. Complete W-8BEN form: This is the US tax form that certifies you’re a non-US person, ensuring the 30% withholding rate applies (not 0%, which would trigger backup withholding). It needs renewal every 3 years.
5. Monitor and manage: You’re now responsible for tracking corporate actions, earnings, dividends, and position sizing.

The W-8BEN step is critical and often overlooked by new investors. Not completing it correctly can create tax headaches downstream.

Buying a Local or SGX-Listed ETF

1. Choose your ETF: On SGX, options include the Lion-Phillip S&P 500 ETF (SGD-hedged), the Nikko AM Shenton Short Duration Bond ETF, and various iShares and Vanguard products accessible through international brokerage accounts. The CSPX (iShares Core S&P 500 UCITS ETF) listed on London Stock Exchange is widely accessible via Singapore brokerages.
2. Check the domicile: Ireland-domiciled = 15% US dividend withholding. Luxembourg-domiciled = varies. US-domiciled (like SPY, VOO) = 30% withholding, plus estate tax risk. For non-US investors, avoid US-domiciled ETFs.
3. Choose accumulating vs. distributing: Accumulating reinvests dividends automatically; distributing pays them out. For long-term compounding, accumulating is typically superior for investors in non-dividend-tax jurisdictions.
4. Place your order: Same as any stock purchase.
5. Set and forget: The fund manager handles all rebalancing, corporate actions, and dividend reinvestment. Your job is done.

The Behavioural Dimension

This is underrated in almost every investing article. Direct stock ownership introduces emotional volatility that ETF investors are partially shielded from. If you own 20 stocks individually, a bad earnings report on any one of them feels personal. You’re more likely to sell in panic or double-down on losers out of stubbornness. An ETF holding 500 companies smooths that emotional jaggedness significantly.

Studies on investor behaviour consistently show that simplicity improves long-term outcomes. The fewer decisions you’re forced to make, the fewer mistakes you make. An ETF in a standing monthly purchase order is one of the most powerful wealth-building tools in existence — not because of its fee structure, but because it removes you from the equation.

Multiple Perspectives: Who Should Choose What

The Case for Direct US Stock Investing

Best for: Investors with genuine sector expertise, those in capital gains tax jurisdictions who can harvest losses, high-net-worth investors building direct-indexed portfolios, or anyone who wants exposure to a specific stock unavailable in any ETF (think early-stage listed companies, sector-specific plays, or — as Barron’s noted with SK Hynix’s US listing — major international companies cross-listing on US exchanges).

The Case for Ireland-Domiciled ETFs

Best for: The overwhelming majority of non-US retail investors. Singapore investors, UK investors, European investors, Southeast Asian investors — anyone without a US tax treaty who pays 30% on US dividends directly will almost always be better served by an Ireland-domiciled fund. The tax efficiency alone is worth it. Add in automatic rebalancing, zero estate tax exposure, and behavioural benefits, and it’s not close for long-term, passive-style investors.

The Case for a Hybrid

Best for: Experienced investors who want a core ETF position (say, 70–80% of their US equity allocation) for stability and tax efficiency, with a satellite portfolio of individual stocks (20–30%) where they have genuine conviction. This is actually how many professional multi-asset investors construct portfolios — index the base, express views at the margin.

Impact and Outlook: Where Is This Debate Heading?

Several macro trends are reshaping this decision in 2026 and beyond:

1. The Cross-Listing Wave

As Barron’s highlighted in its coverage of SK Hynix’s US listing, major non-US companies are increasingly choosing to list on US exchanges to access deeper capital markets and institutional investor bases. This means the universe of “direct US stocks” is expanding beyond American companies — you can now get exposure to global tech champions through US-listed shares. That makes the direct route more internationally diversified than it used to be, somewhat blunting one argument for ETFs (diversification). But it doesn’t solve the tax problem.

2. The ETF Fee Race Continues

Expense ratios on broad market ETFs are approaching zero. The Fidelity ZERO index funds in the US literally charge 0% (for US investors). For non-US investors, UCITS ETFs are hovering at 0.03%–0.07% for the biggest products. The cost argument for managing your own direct portfolio grows weaker by the year.

3. Regulatory and Tax Landscape

Tax treaties are occasionally updated, and there’s ongoing regulatory attention to the estate tax treatment of foreign-held US securities. Any change to the Ireland-US tax treaty would significantly alter the ETF calculus. Similarly, if Singapore were to introduce a capital gains tax (currently there is none), the entire framework for direct stock investing would shift. Monitor your tax environment — it’s the single biggest lever in this decision.

4. Platform Consolidation and Zero-Cost Access

Commission-free US stock trading is now essentially universal in Southeast Asia, driven by players like Moomoo. This has democratised access but also increased retail investor activity — and with it, retail investor mistakes. The accessibility of direct investing doesn’t change the fundamentals of whether it’s wise.

Key Takeaways: Your Decision Checklist

Before you decide, run through this checklist honestly:

The Actionable Recommendation by Investor Type

• 🟢 Beginning investor (<$50K portfolio): Ireland-domiciled accumulating ETF (e.g., CSPX or VUSA via IBKR or Moomoo), monthly standing order, ignore the noise. Full stop.
• 🟡 Intermediate investor ($50K–$250K, some conviction plays): 70% core Ireland-domiciled ETF + 30% direct US stocks in your highest-conviction themes. Rebalance annually.
• 🔵 Sophisticated investor ($250K+, active strategy): Consider direct indexing for tax-loss harvesting, complemented by individual stock positions. Engage a tax adviser familiar with cross-border investing.
• 🔴 Anyone worried about estate planning: Get legal advice. US estate tax on direct US securities is a real risk above $60,000 USD in US situs assets. An ETF wrapper eliminates this exposure.

Conclusion: Stop Treating This as an Either/Or Decision

The framing of “local ETF vs. direct US stocks” is too binary for the nuance the question deserves. The honest answer for most non-US retail investors — and particularly Singaporean investors — is that an Ireland-domiciled accumulating ETF should be the core of any US equity allocation. The tax arithmetic on dividends is simply too compelling to ignore, and the estate tax exposure of direct US securities is a landmine that doesn’t get enough airtime in retail investing circles.

That said, direct US stock investing isn’t wrong — it’s just right for a specific investor profile. If you have genuine sector knowledge, a tax treaty that reduces your withholding burden, and the emotional discipline to not panic-sell on bad earnings days, then building a satellite portfolio of individual US stocks alongside an ETF core is a legitimate strategy.

What’s not legitimate is buying individual US stocks because it feels more exciting than an ETF, because you follow a particular stock on TechStock² or get live alerts on your phone, or because zero-commission trading makes it feel like there’s no cost. There’s always a cost — it’s just sometimes hidden in your tax return, your FX conversion, or the return you missed while you were overthinking your next trade.

The best investment strategy is the one you can stick to, understand completely, and that doesn’t surprise you with hidden costs at the worst possible moment. For most people reading this, that’s a well-chosen, Ireland-domiciled ETF, automated, and largely ignored. The irony is that the boring choice almost always wins.
