What are US ETFs? Types, How They Work

A US ETF (Exchange-Traded Fund) is a basket of investments with stocks, bonds, or other assets, listed on American stock exchanges like the NYSE or Nasdaq, which you can buy or sell like a regular share. Unlike a mutual fund, where you invest at the end of the day at a fixed price, an ETF trades in real time throughout the trading session.

This guide explains what US ETFs are and how they work, the key differences between US ETFs and Indian mutual funds, types of US ETFs available, which ETFs are most relevant for Indian investors, how to actually buy them, basically everything you need to decide whether US ETFs belong in your portfolio.

What is a US ETF?

Think of a US ETF like a thali at a restaurant. Instead of ordering one dish (one stock), you get a full plate, basically many investments bundled together. The 'US' part simply means it's listed and traded on American stock exchanges.

For Indians, US ETFs offer a straightforward way to invest in some of the world's most powerful companies like Apple, Microsoft, Nvidia, Amazon, all in one go, at low fees, and through a single transaction.

Quick example: When you buy one unit of VOO (Vanguard S&P 500 ETF), you instantly own a tiny piece of all 500 of America's biggest companies for an annual fee of just 0.03%, or ₹30 on every ₹1 lakh you invest.

The moment you buy an ETF, you're diversified across dozens, hundreds, or even thousands of companies, without having to pick each one yourself.

How Are US ETFs Different from Indian Mutual Funds Investing in the US?

If you've come across funds like Motilal Oswal Nasdaq 100 FoF or Mirae Asset S&P 500 FoF, you've already seen one way to get US market exposure from India. These are Indian mutual funds, called Fund of Funds (FoFs), that invest your money into US ETFs on your behalf. Here’s a table to understand what's the difference between doing that and just buying the US ETF yourself?

Cost and tax reality check: A typical Indian FoF investing in US markets charges 0.5%-1.7% per year on top of the underlying ETF's own cost. VOO itself charges just 0.03%. That double layer of fees quietly eats into your returns over time. Add to that the tax difference: direct US ETFs qualify for 12.5% LTCG after 24 months, while Indian FoFs are taxed at your slab rate (up to 30%) no matter how long you hold. 

For a long-term investor, both factors together make a meaningful difference to what you actually keep.

How Do US ETFs Work?

Understanding a few basic mechanics will help you invest smarter.

1. The Index Tracking Model

Most US ETFs are 'passive', meaning they don't try to beat the market, they just copy it. An ETF tracking the S&P 500, for example, holds the exact same 500 stocks in the same proportions. When Apple makes up 7% of the S&P 500, it makes up roughly 7% of the ETF too.

This passive approach is why costs are so low. There's no expensive team of analysts trying to outsmart the market. The ETF simply mirrors the index.

2. NAV vs. Market Price: What You Actually Pay

Every ETF has a NAV (Net Asset Value) which is the true value of all assets it holds, divided by the number of units. But when you buy an ETF on the exchange, you pay the market price, which can be slightly above or below NAV based on demand and supply at that moment.

The difference rarely matters much. Large institutional players called Authorised Participants (APs) monitor this gap and step in whenever it widens, keeping market price tightly aligned with NAV. Think of them as the balancing mechanism that keeps the ETF fairly priced.

Example: Imagine a basket of 10 mangoes worth ₹100 in total. The NAV is ₹10 per mango. If too many people want the basket at once, the price might momentarily go to ₹10.05. But APs quickly bring it back to ₹10 by creating more baskets. That's how ETF pricing stays fair.

3. How ETF Units Are Created and Destroyed

Unlike a stock where supply is fixed, ETF units are created and redeemed daily to meet investor demand. When demand rises, APs buy the underlying stocks and hand them over to the ETF issuer in exchange for new ETF units. When demand falls, the reverse happens. This process keeps the ETF liquid and fairly priced at all times.

Types of US ETFs

There are thousands of ETFs listed in the US covering nearly every corner of the market. Here are the main categories relevant to Indian investors:

Equity ETFs (Index, Sector, Thematic)

These are the most popular ETFs, they invest in stocks. Within equity ETFs, you have three sub-types:

• Index ETFs track broad market indices like the S&P 500 (top 500 US companies) or the Nasdaq-100 (top 100 tech-heavy companies). Examples: VOO, SPY, QQQ, VTI.
• Sector ETFs focus on one industry. XLK tracks only technology companies; XLF covers financials; XLE covers energy. Useful if you have a strong view on a specific sector.
• Thematic ETFs invest around a theme, for example, artificial intelligence (BOTZ, AIQ), clean energy (ICLN), semiconductors (SOXX). These come  with higher potential returns but also higher risk and volatility.

Bond ETFs

Bond ETFs invest in debt; either US government bonds or corporate bonds. They're typically used by investors who want regular income with lower risk than stocks. Popular examples include BND (Vanguard Total Bond Market), AGG (iShares Core US Aggregate Bond), and TLT (iShares 20+ Year Treasury Bond). These are less common among Indian retail investors but worth knowing about for balanced portfolios.

Commodity ETFs

These track the price of a physical commodity. GLD (SPDR Gold Shares) is the most famous, it tracks gold prices without you needing to hold physical gold. USO tracks oil prices. There are also ETFs available for various other commodities like Silver (SLV), Copper (COPX), Platinum (PPLT), Uranium (URA), etc.

International ETFs (Invest in China, Japan, Europe via US)

A unique advantage of the US ETF ecosystem is its reach. From a single US brokerage account, you can invest not just in America but across the globe through ETFs. MCHI gives you China exposure, EWJ tracks Japan, VGK covers Europe, and KSA tracks Saudi Arabia. 

Here’s a simple table you can refer to for a simple idea on various ETF types:

Leveraged ETFs

Leveraged ETFs use financial derivatives like a combination of futures, swaps, options to multiply the daily returns of an index; typically 2x or 3x. So if the S&P 500 goes up 1% in a day, a 2x leveraged S&P 500 ETF aims to go up 2%. The reverse is equally true, so a 1% fall becomes a 2% fall in your portfolio.

Examples: TQQQ (3x Nasdaq-100), UPRO (3x S&P 500), SSO (2x S&P 500), SOXL (3x Semiconductors).

One important thing to understand, Leveraged ETFs are not beginner instruments, these are designed for short-term trading, not long-term holding. They reset every single day, which creates a compounding problem over time. 

Here's a simple example:

Say the index falls 10% on Day 1, then rises 10% on Day 2. You're roughly back to where you started on the index. But a 3x ETF falls 30% on Day 1, then rises 30% on Day 2; and you're still down 9% overall. The math works against you the longer you hold, especially in a choppy, sideways market.

Inverse ETFs            

Inverse ETFs are designed to go up when the market goes down and vice versa. They use derivatives to deliver the opposite of an index's daily return; so if the S&P 500 falls 1%, an inverse S&P 500 ETF aims to gain 1%. Traders use them to hedge existing positions or to profit during a market downturn without short-selling directly.

Examples: SH (1x inverse S&P 500), PSQ (inverse Nasdaq-100), SQQQ (3x inverse Nasdaq-100), SPXU (3x inverse S&P 500).

Like leveraged ETFs, these are short-term tools built for active traders; not for buy-and-hold investors. Holding an inverse ETF during a rising market steadily destroys value.

Important note: Both, leveraged and inverse ETFs exist in the US markets and are accessible, but they come with complexity and risk that goes well beyond standard ETF investing. For most long-term investors, they're worth knowing about and not worth using.

How Indian Investors Can Buy US ETFs

Thanks to RBI's Liberalised Remittance Scheme (LRS), every Indian resident can legally invest up to $2,50,000 (around ₹2.1 crore) per financial year in US markets, including ETFs. Here are the main routes:

Route 1: Direct Investment via LRS (Recommended for most)

This is the most direct and increasingly popular method. You open an international brokerage account through platforms that integrate with Indian banking for LRS compliance. INDmoney, for instance, allows you to invest in US ETFs directly from your Indian bank account, the platform handles the remittance, currency conversion, and compliance paperwork.

Fractional shares: You don't need to buy a full unit. If a single ETF unit costs $400, you can invest just $10 and own a fraction of it. This makes US ETFs accessible even with small amounts.

Route 2: GIFT City (Gujarat International Finance Tec-City)

India's GIFT City IFSC (International Financial Services Centre) allows certain US ETF-linked instruments to be traded in India through NSE IFSC. This route has no LRS requirement, but the product range is currently limited compared to direct US market access. It's a growing space worth watching.

Route 3: Indian Mutual Funds with US Exposure (Fund of Funds)

Several Indian mutual funds, called Fund of Funds (FoFs), invest in US ETFs on your behalf. Examples include Motilal Oswal Nasdaq 100 ETF FoF and Mirae Asset NYSE FANG+ ETF FoF. You invest in INR, using SIP, with no need for an overseas account.

US ETFs vs Individual US Stocks: Which Is Better for Indian Investors?

The honest answer is that it depends on what kind of investor you are.

Buying individual US stocks like Apple, Nvidia, or Tesla feels exciting. You're backing a company you believe in. But for most people, that conviction isn't backed by the kind of research that makes stock-picking work, like reading quarterly earnings, understanding competitive moats, tracking management changes, etc.. Without that, you're essentially guessing with concentration.

ETFs remove that burden. When you buy VOO, you're not betting on any one company. You're betting on American business as a whole and historically, that's been a bet that has paid off over long horizons.

That said, ETFs and individual stocks aren't mutually exclusive. A sensible approach many investors follow: build your core US portfolio in broad ETFs like VOO or VTI, and if you have strong conviction in a specific company and have done your homework, allocate a small portion, say 10-20% of your US holdings, to individual stocks.

What doesn't work is the reverse: going all-in on three or four US stocks because they've been in the news, and leaving no room for the diversification that protects you when one of them has a bad year.

The simple rule of thumb: If you can't explain why a company will be worth more in five years than it is today, simply buy the ETF.

Expense Ratios in US ETFs: What to Look For

The expense ratio is the annual fee charged by the ETF issuer to manage the fund. It's deducted automatically from the fund's assets, you never pay directly, but it silently erodes your returns over time.

Quick example: You invest ₹10 lakh in a US ETF with a 0.03% expense ratio versus an Indian fund-of-funds with a 1.5% expense ratio. Over 20 years at 12% annual returns, the low-cost ETF gives you roughly ₹94 lakh. The high-cost fund gives you around ₹73 lakh. That's a ₹21 lakh difference, purely because of fees.

Here's how US ETF costs compare to other options:

Beyond expense ratio, also check:

• AUM (Assets Under Management): Larger AUM means more liquidity and tighter bid-ask spreads. VOO has over $500 billion in AUM, it's the largest ETF in the world by assets.
• Tracking error: How closely does the ETF follow its index? Lower tracking error = better execution.

Bid-ask spread: The difference between what buyers pay and sellers receive. Highly liquid ETFs like VOO and QQQ have extremely tight spreads, in simple terms, the tighter the spread is, the better it is for you.
