When is the best time of day to trade an ETF?

The short answer

ETF trading is generally clearer when the markets for most of its underlying investments are open. Spreads can be wider near the start or end of the trading day, during market stress or when the underlying market is closed.

Why it matters

An ETF can trade on a European exchange while holding investments from another region. Market makers are firms that quote prices at which they will buy and sell. They estimate the value of those holdings when quoting buying and selling prices.

If the underlying market is open, current prices are easier to observe. If it is closed, the market maker may allow for greater uncertainty by quoting a wider spread.

There is no single perfect trading time for every ETF. It depends on the exchange listing, the underlying assets and current market conditions.

Large market announcements can also cause rapid price changes and wider spreads.

A simple example

A US equity ETF trades on a European exchange during the morning, before US stock markets open. The ETF can still be bought or sold, but its spread may reflect uncertainty about where US shares will open.

Later in the European afternoon, both markets may be open and prices may be easier to establish.

What to check

• Is the ETF’s exchange open?
• Are the main underlying markets open?
• How wide is the current bid–ask spread?
• Is a major market announcement expected?
• Would a limit order provide useful price control?

Key term explained

Market overlap is the period when the ETF’s exchange and important underlying markets are open at the same time.

Trading time can affect the price you receive, but it does not change the ETF’s long-term investment exposure.
