Picture this: It's Thursday night and news breaks that a major tech company has been hit with a cybersecurity breach. Within minutes, social media is ablaze and investors are scrambling to assess the damage.
It used to be that traders would have to wait until Friday morning's opening bell to alter their positions, but now several brokerages—including Schwab—offer 24/5 trading. This allows clients to trade from 8 p.m. Eastern time (ET) on Sunday through 8 p.m. ET on Friday with just five minutes of downtime before and after the regular trading session (see "Extended-hours trading with the thinkorswim® platform").
However, it's not all upside. Traders should understand the heightened risks around 24/5 trading—and what they can do to adjust their approach.
More opportunity, more risk
There are fundamental differences to trading outside standard market hours:
- Less liquidity: With fewer traders active after hours, even popular stocks experience lower trading volumes, which can lead to wider bid/ask spreads that could amplify losses or reduce profits.
- More volatility: By the same token, having fewer trades means stocks are potentially exposed to greater and more frequent price fluctuations. This can be particularly likely during earnings season, since many earnings announcements occur after the standard trading day has ended.
- Uncertain prices: Unlike regular trading hours, during which brokers must fill orders at the best available price across all trading venues, an after-hours quote may not reflect the best available price in the market.
- Broker-imposed restrictions: Most brokers accept only limit orders for trades placed outside regular market hours, meaning your trade will execute only if the stock reaches your specified price (or better). A broker may also limit trades to just a portion of the market or cancel unfilled after-hours orders prior to the start of regular trading hours.
Learning to adjust
It's wise to go slow and use more cautious tactics when it comes to extended-hours trading, which might include:
- Taking smaller positions: Generally speaking, many traders may not see after-hours trading as the time to take big swings. Instead, traders might consider buying or selling just a portion of their overall trade at different times to reduce the risk of uncertain pricing. For example, if a test trade goes through at an advantageous price, it might make sense to open another similarly sized position in short order. However, if the initial trade doesn't go as intended, waiting until conditions improve could make more sense.
- Focusing on more-liquid stocks: Stocks that attract more investor attention may have higher trading volumes and therefore greater liquidity, which could result in narrower bid-ask spreads and a better chance of transacting at a desired price.
- Avoiding off-peak hours: Liquidity is typically highest in the hour before the market opens and the hour after it closes (the latter being when many companies report earnings). Outside these hours, traders tend to be more selective about what news warrants immediate action.
Traders using Schwab's thinkorswim trading platform can also use the active trader ladder function to help manage price.
