USBC shares surge 76.99% after-hours on finalized triparty agreement with Uphold and Vast Bank for tokenized deposits.

think> Okay, let's tackle this query. The user wants me to act as a financial analyst explaining a stock's price movement based on news events. The stock in question is USBC, which had a huge after-hours gain of 76.99%, but the example in the input shows a 7.4% pre-market move. Wait, the input says "USBC盘后 after-hour up76.99115044%", so the percentage is over 76%, which is a massive jump. But the news events mention a 7.4% pre-market increase. Hmm, that's conflicting. The user might have made a typo here, but I need to work with the data provided. First, the stock performance is after-hours, so the movement is in the after-hour session. The percentage is 76.99%, which rounds to 77.0%. But the news events all mention a 7.4% pre-market increase. That's a big discrepancy. Maybe the user input has conflicting data. The instruction says to use the given stock performance, so I should go with the 76.99% after-hours gain, but the news events refer to pre-market. That's confusing. Wait, maybe the user made a mistake in the percentage, but I have to follow the input as given. So the stock moved up by 76.99% after hours, but the news event is about a pre-market 7.4% rise. That doesn't align. Wait, perhaps the 76.99% is a typo and should be 7.4%? Or maybe the user provided two different pieces of information. The key here is that the news event is about a pre-market 7.4% jump, but the stock's performance is after-hours. So the movement the user is asking about is after-hours, but the news event is about pre-market. That's a problem because the news event is in pre-market, but the stock's movement is after-hours. Unless the after-hours movement is a continuation of the pre-market move. But the user's input says the stock's performance is after-hours with a 76.99% gain. That's a huge jump, which is unusual. Maybe it's a decimal error, like 7.699% instead of 76.99%. But the user wrote 76.99115044%, so they want it rounded to two decimals, which would be 76.99%. But in reality, a stock can't jump that much unless it's a penny stock or there's a major event. Assuming the user's input is correct, the stock moved up 76.99% after hours. The relevant news is the strategic partnership announcement, which caused a 7.4% pre-market rise. So the after-hours movement might be a continuation of the pre-market news, but the percentage is way higher. Maybe the user is testing if I can reconcile the two. But according to the instructions, I need to use the given stock performance and the relevant news. The news events are all about the same strategic partnership, so they are relevant and bullish. The stock's after-hours movement is in the same direction as the news (up), so the cause is the partnership. I need to write a concise explanation. The stock surged 76.99% after hours, which is after the pre-market news. The key is to link the after-hours movement to the same news event. The example given in the instructions shows that the movement is linked to the news even if it's in a different session. So the answer should mention the after-hours session and the pre-market news as the cause. So the summary would be: USBC surged 77.0% in after-hours trading following the announcement of a strategic partnership with Uphold and Vast Bank to develop tokenized bank deposits. The triparty agreement aims to create regulated digital dollar infrastructure, supporting faster settlements and new digital asset services. Wait, but the example in the instructions uses the percentage from the stock performance, so I need to round 76.99115044% to two decimals, which is 76.99%, but the example rounded to 4.23%. The user's input says to round to two decimal places and remove trailing zeros. So 76.99% is already two decimals, no trailing zeros. So the answer should state the movement as 76.99% after-hours. But the news events mention 7.4% pre-market. However, the user's input says the stock performance is after-hours with that percentage. So the answer should focus on the after-hours movement and link it to the same news that caused the pre-market rise. Therefore, the final answer should state that USBC's after-hours.
