ETF vs Shares: What's the Difference?

What is a Share?

A share represents a unit of ownership in a company. When you buy shares in a company, you become a shareholder entitled to a proportion of that company's profits (typically paid as dividends) and any increase in the company's value over time.

Shares are bought and sold on stock exchanges such as the London Stock Exchange (LSE), New York Stock Exchange (NYSE), or NASDAQ. Their price fluctuates based on company performance, investor sentiment, and broader market conditions.

Key characteristics of shares:

• Direct ownership in a single company
• Potential for dividends and capital growth
• Higher individual risk — performance tied to one company
• Requires research into individual businesses
• Stamp duty of 0.5% applies on UK share purchases

What is an ETF?

An Exchange Traded Fund (ETF) is a fund that tracks the performance of an index, sector, commodity, or asset class. Like a share, it trades on a stock exchange and its price updates throughout the day. Unlike a share, it holds a collection of underlying assets rather than representing ownership in a single company.

For example, an ETF tracking the S&P 500 holds positions in all 500 companies in that index. When you buy one unit of that ETF, you gain proportional exposure to all 500 companies simultaneously.

Key characteristics of ETFs:

• Instant diversification across multiple assets
• Lower individual company risk
• Typically lower costs than actively managed funds
• No stamp duty on most ETFs
• Suitable for both short-term trading and long-term investing

ETF vs Shares: Key Differences

Diversification: The Core Advantage of ETFs

The single biggest advantage of ETFs over individual shares is built-in diversification. When you hold shares in one company, your entire investment is exposed to that company's specific risks — a profit warning, a regulatory fine, or a change in management can wipe significant value from your holding overnight.

An ETF spreads that risk across many companies. Even if one constituent performs poorly, its impact on the overall fund is limited by the other holdings.

This is why ETFs are often recommended as a core building block for long-term investors, while individual shares tend to appeal to more active investors with the time and expertise to research specific companies.

Costs: ETFs vs Shares

Both ETFs and shares are relatively low-cost investment instruments compared to actively managed funds, but their cost structures differ.

ETF costs:

• Total Expense Ratio (TER): An annual management fee typically ranging from 0.03% to 0.75% for passive index-tracking ETFs. This is deducted from the fund's assets automatically — you don't pay it directly.
• Spread: A small bid/ask spread applies when buying and selling, as with shares.
• No stamp duty: Most ETFs listed on the LSE are exempt from the 0.5% stamp duty that applies to UK shares.

Share costs:

• Stamp duty: 0.5% on purchases of UK-listed shares.
• Broker commission: Depending on your platform.
• Spread: Bid/ask spread applies.
• No management fee: You pay no ongoing management charge for holding shares directly.

For long-term investors, the absence of stamp duty and low TERs make ETFs highly cost-efficient. For active traders making frequent short-term moves, the spread and any commission are the primary cost considerations for both instruments.

If you want to trade on short-term price movements in either ETFs or shares without owning the underlying asset, CFDs offer an alternative — though with significantly higher risk due to leverage.

Which Is Better for Long-Term Investing: ETFs or Shares?

For most UK investors building long-term wealth, ETFs offer a more straightforward and lower-risk starting point. The combination of built-in diversification, low costs, and no stamp duty makes them an efficient vehicle for broad market exposure.

However, individual shares offer something ETFs cannot: the potential for outsized returns from a single high-performing company. Investors who correctly identify a high-growth company early can generate returns that significantly outperform any index-tracking ETF. The trade-off is higher risk and the requirement for deeper research.

Many investors hold both — using ETFs as a diversified core and individual shares as higher-conviction satellite positions.

ETFs may suit you if:

• You are investing for the long term
• You want broad market exposure with minimal research
• You prefer lower volatility and built-in diversification
• You are starting out and building foundational investment knowledge

Shares may suit you if:

• You have the time and expertise to research individual companies
• You want to target specific companies you believe will outperform
• You are comfortable with higher individual company risk
• You want direct ownership and voting rights in specific businesses

Types of ETFs Available to UK Investors

Not all ETFs are the same. The main categories available to UK investors include:

• Equity ETFs — track a stock market index such as the S&P 500, FTSE 100, or MSCI World. The most common and widely held type.
• Bond/Fixed Income ETFs — provide exposure to government or corporate bonds. Lower risk than equity ETFs, typically used to balance a portfolio. Learn more about fixed income ETF options.
• Commodity ETFs — track the price of commodities such as gold, oil, or agricultural products. Useful for portfolio diversification and inflation hedging. 
• Sector ETFs — focus on a specific industry such as technology, healthcare, or clean energy. Higher concentration risk than broad market ETFs but useful for targeted exposure. See our guide to AI ETFs as one example.
• Leveraged ETPs — a more complex product that amplifies returns (and losses) using leverage. Suitable only for experienced traders. 

ETFs vs Shares: Tax Treatment in the UK

Both ETFs and shares held directly are subject to the same UK tax framework:

• Capital Gains Tax (CGT): Profits above the annual CGT allowance (currently £3,000 for 2024/25) are subject to CGT at 18% (basic rate) or 24% (higher rate) for investments.
• Dividend tax: Income from dividends above the £500 dividend allowance is taxable at your marginal rate.
• ISA wrapper: Both ETFs and shares can be held within a Stocks & Shares ISA, sheltering all gains and income from tax entirely. XTB offers a Stocks & Shares ISA — explore how it works.

Capital at risk. Investment values can rise or fall. Tax treatment depends on your individual circumstances and ISA regulations which may change.
