# After-hours trading | NVIDIA's held stocks are launching the second wave of attacks!

**After-hours surge in AI concept stocks, with BBAI, GFAI, and AI rising by 15%, 6.6%, and 2% respectively.**

It is worth mentioning that NVIDIA's holding stock SOUN surged by 12% in after-hours trading, skyrocketing by 24.8% overnight, up by 47% so far this week, and over 300% since 2024.

Industry insiders believe that the volatility of hot small companies is significant, and risks should be noted.

Brokerage stock Robinhood surged by 10.7% in after-hours trading, with a cumulative increase of 60% since the financial report was released on February 13, driven by the bullish market in the US stock market, leading to a rebound in brokerage stocks. It is worth noting that the brokerage stocks announcing financial reports before the market today include FUTU, while TIGR will announce its financial report on March 20, both showing considerable gains recently.

Furthermore, after-hours trading also saw an increase in blockchain concept stocks such as HUT, MSTR, COIN, etc. BTC remains at a high level.

**What is after-hours trading?**

The emergence of after-hours trading allows trading in the US stock market to be conducted 24 hours a day, better aligning with the working hours of people in the East.

Investors can trade US stocks promptly based on the market conditions in the Asia-Pacific region and unexpected events in Hong Kong and the US stock market, without having to wait for the US stock market to open in the evening.

The after-hours trading period for the US stock market is from 8:00 pm to 3:50 am Eastern Time from Sunday to Thursday, with after-hours trading, pre-market trading, intraday trading, and after-hours trading together forming the 24-hour trading of the US stock market.

**Risk Warning**

The trading volume in after-hours trading is generally much smaller than during regular trading hours, and usually smaller than in after-hours and pre-market trading. Please be aware of slippage risks. Additionally, there is significant volatility risk around major events such as the release of financial reports by listed companies.
