loanDepot shares surge 12.30% after-hours as Rocket Cos., LoanDepot rise postmarket.

think> Okay, let's start by breaking down the user's query. They want me to act as a financial analyst explaining a stock price movement linked to relevant news. The input is in Chinese, but I need to process it in English. First, the stock performance is "loanDepot盘后 after-hour up 12.29508197%". So the stock, loanDepot (LDI), rose 12.3% in after-hours trading. The trading period is after-hours, which I need to mention. Now, looking at the news events provided. There are three reasons. Reason 1 is a news article titled "Rocket Cos., LoanDepot rise more than 5% postmarket" with a summary that both Rocket Cos. (RKT) and LoanDepot (LDI) surged over 5% after hours. The content mentions an article by Ainvest, but it's a bit vague. However, this is directly about the stock's after-hours surge, so it's relevant and likely the main driver. Reason 2 is a generic news page for LDI with no specific info since the content is just "You need to enable JavaScript to run this app." So this isn't useful. Reason 3 is about Monster Jam coming to loanDepot Park, a sports event. While the company's name is in the venue, this seems unrelated to stock performance unless there's a PR angle. But the stock jumped 12%, which is a big move, and the event is in February 2024, which is before the stock movement date (the news is from Jan 8, 2026). Wait, the stock's movement is on Jan 8, 2026, but the Monster Jam event is in 2024. So that's a past event, so it can't be the cause. Therefore, Reason 3 is unrelated. So the relevant news is only Reason 1. The stock's after-hours surge aligns with the news that both LDI and RKT rose over 5% postmarket. The article asks what's driving the surge but doesn't specify the reason. However, since the movement is mentioned in the news, that's the key factor. The other news isn't relevant. Now, the user's example shows that when the news is directly about the company's announcement, you use that. Here, even though the reason isn't specified in the news content (it's just a summary), the fact that the news reports the surge and asks about the cause suggests that the news is the trigger. So the movement is attributed to the after-hours surge mentioned in the news. Check if there's any contradiction. The stock went up 12.3%, and the news says both rose more than 5%, so the movement is in line. The other news is either irrelevant or outdated. So the answer should link the stock's movement to the news of the surge mentioned in Reason 1. Now, format the response as per the example. Round the percentage to two decimals (12.30% becomes 12.30% but the instruction says to remove trailing zeros, so 12.30% becomes 12.30%? Wait, the example rounds 4.230769% to 4.23%, so here 12.29508197% is approximately 12.29508197, which rounds to 12.30% when rounded to two decimals. But the user says to round to two decimal places and remove trailing zeros. Wait, 12.29508197 is 12.29508197%, so when rounded to two decimal places, it's 12.30% (since the third decimal is 5). But the example shows 4.230769 becomes 4.23. So maybe the user wants two decimal places, so 12.30%, but the instruction says to remove trailing zeros. So if it's .30, then it becomes 12.30% but if it's .29 or .30, but the example shows 4.23% as two decimals. So perhaps the user wants exactly two decimal places, regardless of trailing zeros. Wait, the example input had 4.230769% which rounds to 4.23%, and the output shows 4.23%. So in this case, 12.29508197% is 12.30% when rounded to two decimal places. So the output should be 12.30%, but the instruction says to remove trailing zeros. Wait, 12.30% has a trailing zero.
