# After-hours trading: NVIDIA hits a new high again, SMCI surges by 15%.

In the past two trading days, AI concept stocks continued to rise, with AMD soaring nearly 15% in two days, hitting consecutive new highs; NVIDIA surged 4% on Friday, and currently rose another 1.76% in after-hours trading, setting a new high:

AI rising star SMCI surged 15.6% in after-hours trading. On the news front, SMCI was successfully included in the S&P 500 index, attracting a considerable amount of passive funds (such as ETFs).

**Top gainers in after-hours trading:**

Leading the gains are AI concept stocks, including not only SMCI, but also small companies like BBAI, GFAI, CXApp, XiaoI Robot, as well as blockchain concept stocks MSTR, CLSK, Gan Technology, HUT, and others.

It is worth mentioning that TSMC surged 3.2% in after-hours trading, approaching its historical high:

As of the seven days ending on February 28, a significant amount of funds flowed into global stock funds, driven by the continuous rise of the US stock market and increased investor interest in tech stocks, especially after NVIDIA released strong profit forecasts and the growing enthusiasm for artificial intelligence (AI). Data from the London Stock Exchange Group (LSEG) shows that investors bought a net $6.98 billion in global stock funds that week, compared to a net withdrawal of about $2.93 billion the previous week.

**What is after-hours trading?**

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

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

The after-hours trading period for US stocks is from 8:00 pm to 3:50 am Eastern Time from Sunday to Thursday, forming part of the 24-hour trading cycle of US stocks along with pre-market trading, regular trading hours, and post-market trading.

**Risk Warning**

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