What Is an ETF? A Plain-English Guide for UK Investors

An ETF (exchange-traded fund) is a single investment that holds a basket of many underlying assets – such as shares or bonds – and trades on a stock exchange like an ordinary share. Buying one ETF can give you exposure to hundreds or thousands of companies at once, at a low ongoing cost. ETFs are the building blocks SCM Direct uses to construct its discretionary portfolios.

ETF in one sentence

An ETF pools money from many investors to buy a diversified basket of assets, then divides ownership into shares you can buy and sell on an exchange throughout the trading day.

ETFs versus Stock & Shares

A share gives you a stake in one company; an ETF gives you a stake in hundreds at once – instant diversification in a single purchase.

How does an ETF work?
  • It holds a basket. Most ETFs track an index (for example, the FTSE 100 or a global equity index), holding the same securities in the same proportions.
  • It trades on an exchange. Unlike a traditional fund priced once a day, an ETF’s price updates live during market hours, so you can see exactly what you’re paying.
  • It’s transparent. ETFs typically publish their full holdings daily, so you can see precisely what you own.
  • It’s low cost. Because most ETFs track an index rather than relying on a manager to pick stocks, their ongoing charges are generally lower than those of actively managed funds.
ETF versus an index fund versus an active fund

ETFs and index funds are close cousins, with both usually tracking an index at low cost.

The main practical differences are how they trade (live vs once a day) and how holdings are disclosed. Active funds aim to beat the market and charge more for the attempt; UK regulators and long-running studies (for example, the FCA’s Asset Management Market Study and the SPIVA reports) have found that, after fees, most active funds do not consistently outperform their benchmark over the long term.

What does an ETF cost?

Costs matter because they are one of the few things an investor can control, and they compound over time. With ETFs there are usually three:

  1. Ongoing Charges Figure (OCF): the fund’s annual running cost, deducted from the fund.
  2. The spread: the small difference between the buy and sell price on the exchange.
  3. Transaction costs: the cost of buying or selling, and of trades made inside the fund.

SCM Direct’s philosophy is that all of these should be visible. Hidden or layered charges are exactly what the firm’s founders campaigned against through the True & Fair Campaign.

Are ETFs safe? Understanding the risks

ETFs are mainstream, regulated investment vehicles, but, like all investments, they carry risk:

  • Market risk: if the underlying assets fall in value, so does the ETF.
  • Tracking difference: an ETF may not perfectly match its index.
  • Currency risk: ETFs holding overseas assets are affected by exchange-rate moves.
  • Liquidity: most large ETFs trade easily, but some niche ones less so.
  • Diversification – owning many assets rather than a few – is one of the main ways ETFs help manage risk, but it does not remove it.
How SCM Direct uses ETFs

SCM Direct builds its discretionary portfolios almost entirely from ETFs – typically 15 to 20 carefully selected funds per portfolio – to give clients broad, global diversification at low cost.

The typical SCM Direct Total Annual Cost is 0.85% all-in – covering management, custody, the underlying ETF charges, and trading costs, with no performance fees, initial charges, or exit penalties. Eight risk-graded portfolios are available across ISA, SIPP, JISA and General Investment Accounts (GIA).

Capital at risk. The value of investments can go down as well as up, and you may get back less than you invest.

Frequently asked questions
What does ETF stand for?

Exchange-traded fund — a fund that trades on a stock exchange like a share.

Many investors use ETFs because a single fund gives instant diversification at low cost – even the highly respected professional investor, Warren Buffett. Whether any investment is right for you depends on your goals, timeframe and attitude to risk.

Capital is at risk.

Yes. ETFs can be held inside tax-efficient wrappers such as a Stocks & Shares ISA, SIPP or Junior ISA. SCM Direct’s portfolios are available in all of these.

An ETF trades live on an exchange and usually discloses its holdings daily; a traditional fund is priced once a day. Most ETFs track an index at low cost.

Generally, yes.  Index-tracking ETFs usually have lower ongoing charges than actively managed funds, because they don’t pay for a manager to select stocks.

Many do. “Distributing” ETFs pay income out to investors; “accumulating” ETFs reinvest it inside the fund.

Yes. The value of an ETF can fall as well as rise, and you may get back less than you invested.
