ETF trading best practices
Similar to stocks, exchange-traded funds (ETFs) are (as their name suggests) traded on exchanges during market hours, but come with different trading considerations and distinct liquidity characteristics. While trading ETFs isn’t difficult, mistakes can be costly. Consider these best practices to help you along the trading journey.
Avoid trading around market open and close
Timing can play a crucial role in your trading success. Bid-ask spreads are often wider as the market opens and closes, which can subject you to unfavorable execution. To avoid this unnecessary risk, don’t trade ‘market on open’ but rather watch the spreads and give them time to settle before you place your trade. A general rule: Avoid trading ETFs during the first and last half hour of a trading day. This simple guideline may help you achieve a better price and smoother trading experience.
Use limit orders to control your price
Unless you have confidence in various order types, specifically as it relates to ETFs, it is best to use limit orders when buying or selling ETFs. This allows you to set the maximum price you are willing to pay per share, or the minimum price that you are willing to sell for. Think of it like having a safety net that prevents you from paying more (or receiving less) than intended.
Avoid the temptation of market orders
Market orders are often used for stock trading, and the speed of execution makes them tempting for ETFs as well. However, for ETFs, market orders come with the risk of execution at unfavorable prices, especially for those with lower average daily volume. Use limit orders to tap into deeper liquidity and avoid paying more than you should for an ETF.
Use block trades for larger orders
When executing large trades, you may consider using your brokerage's block execution desk. Many brokers provide resources to help you access deep liquidity that may not be visible on electronic platforms. Block trades can also be entered as limit orders, helping you control the maximum price you are willing to pay for each share in a large block you are purchasing or the minimum share price in a large block you are selling. A block trade allows the executing broker desk to seek out the best available price for the trade by requesting competitive quotes from multiple market makers at the same time.
Mark your orders ‘Not Held’ for professional execution
Marking ETF orders as ‘Not Held’ is like requesting a professional trading desk to seek best execution on your behalf. Although typically not necessary for smaller orders, where there is immediate liquidity already available, this tactic can make sense for larger orders.
