To flexibly participate in the U.S. stock market, you must master the pre-market trading hours. This period allows you to adjust investment strategies based on the latest news before the official market opens. The pre-market trading hours in Eastern Time and Hong Kong Time are as follows:
| Trading Session | U.S. Time (ET) | Hong Kong Time (Daylight Saving) | Hong Kong Time (Standard) |

You can refer to the chart below to understand the comparison of pre-market price movements in Eastern Time and Hong Kong Time:

The two major U.S. exchanges—New York Stock Exchange (NYSE) and NASDAQ—both support pre-market trading. You can trade during the pre-market session of these exchanges to capture market opportunities early.
The pre-market trading hours of these two exchanges are identical. You can place orders during this period, but only limit orders are accepted. Pre-market trading typically has lower volume and higher price volatility. You need to pay special attention to liquidity and price gap risks.
According to market data, many investors adjust positions during U.S. pre-market trading hours based on major news or earnings reports. For example, on April 4, 2024, Bitcoin rose 2.6% in the four hours before the U.S. market opened. This reflects the activity and market responsiveness of the pre-market trading session.
You can refer to the table below for the latest prices and volatility of various indices during the pre-market session:
| Time (ET) | Index Name | Exchange | Latest Price | Change | % Change | Open | High | Low | Volume | Open Interest |
|---|---|---|---|---|---|---|---|---|---|---|
| 4:35 | Dow Jones Futures Manual | CBOT | 17527 | 215 | 1.24% | 17527 | 17527 | 17527 | 0 | 0 |
| 7:25 | NASDAQ 100 Futures Manual | CME | 4244 | 55.75 | 0.00% | 4244 | 4244 | 4244 | 0 | 0 |
| 19:36 | S&P 500 Futures Manual | CME | 4421.8 | -42.4 | -0.95% | 4421.8 | 4421.8 | 4421.8 | 6 | 110 |
| 4:15 | Nikkei 225 Futures | CME | 21955 | 35 | 0.16% | 21955 | 21955 | 21955 | 9314 | 15578 |
| 17:48 | Russell 2000 Futures | CME | 1671.2 | -7 | -0.42% | 1676.8 | 1681.1 | 1660 | 3755 | 10790 |
You can see that during the pre-market session, index prices fluctuate rapidly based on market news. This period is crucial for investors who need to react instantly.
Note: The pre-market session has lower trading volume, and prices are prone to gaps. When placing orders, pay special attention to price volatility and liquidity risks.
You can engage in pre-market trading before the U.S. stock market officially opens. This period allows you to adjust investment strategies based on the latest news. Pre-market trading only accepts limit orders. You need to place orders on a broker’s platform, and the system will match them based on your set price. Most brokers automatically display tradable stocks during the pre-market session. You simply select the stock, enter the quantity and price, and submit the order. The broker will attempt to match your order during the pre-market session. If no match is found, the order will be automatically canceled at the end of the pre-market session.
Tip: You can use pre-market trading to quickly react to U.S. company earnings, international news, or sudden events.
Pre-market trading offers several advantages. You can enter the market early to capitalize on major news. You can also adjust positions during market volatility to reduce risks. However, pre-market trading carries higher risks. Trading volume is typically lower, and prices are prone to significant fluctuations. You may encounter insufficient liquidity, leading to wider bid-ask spreads. Some brokers charge higher fees, approximately USD 0.005-0.01 per trade (1 USD ≈ 7.8 HKD). You need to pay special attention to trading costs.
Pre-market trading is suitable for those who need to flexibly adjust their investment portfolios. If you frequently follow U.S. stock market news or need to react quickly to earnings reports or policy news, pre-market trading can be very helpful. Professional investors, short-term traders, and those needing immediate risk hedging often use pre-market trading. If you’re a beginner, it’s recommended to first familiarize yourself with pre-market trading rules and risks before gradually participating.
