Fat Brands-B shares surge 371.88% intraday as trading volume spikes.

think> Okay, let's see. The user provided a stock performance for Fat Brands B that went up 371.875% intraday. The recent news events are all about FAT Brands-B surging by similar percentages, like 468.75%, 650%, etc. The user wants me to determine if these news events are the cause of the stock movement. First, I need to check the trading period. The input says "盘中 intraday", so the movement happened during regular trading hours. The news events mention pre-market and regular trading hours. For example, one news item says "Gainers: $FAT Brands-B... surges 468.75% to $1.82 with a turnover of $67.59 million." Another mentions pre-market with a 650% increase. But the stock's performance here is intraday, so maybe the pre-market news influenced the intraday trading? Wait, the stock's movement is intraday, but the news includes both pre-market and regular trading. The user's input says the stock moved up 371.875% during the day. However, the news reports a 468.75% surge in regular trading. The percentage here is different from the input's 371.875%. But the user's instruction says to round 371.875% to two decimal places, which would be 371.88%. But the news events report higher percentages. Wait, maybe there's confusion here. The user's input says the stock's intraday movement was up 371.875%, but the news events mention a 468.75% surge in regular trading. However, the user's input might have a typo or inconsistency. But according to the instructions, I should use the given stock performance data. The key is to link the movement to the relevant news. The news events all mention FAT Brands-B surging by high percentages, which aligns with the stock's movement. The news also mentions high turnover, which indicates significant trading volume. So, the relevant news events are the ones that mention the stock surging in regular trading hours. The pre-market ones might have contributed to the overall momentum, but the intraday movement is specifically during regular trading. The challenge is that the exact percentage in the input (371.875%) doesn't match the news (468.75%), but maybe the input's figure is a typo or a different calculation. However, the user's instruction says to use the given stock performance. Since all the news events are about the same stock (FAT Brands-B) and the surge, they are relevant. The movement is upward, and the news is bullish. So, the summary should mention the intraday surge, the percentage (rounded to 371.88%), and link it to the news about the stock surging with high turnover. The key point is the surge in regular trading hours as per the news. But wait, the user's input says the stock's intraday movement was up 371.875%, but the news reports a 468.75% surge in regular trading. There's a discrepancy here. Maybe the user intended to say that the stock had a surge in regular trading, but the input's percentage is different. Alternatively, perhaps the input's percentage is correct, and the news's 468.75% refers to a different time frame. For example, the news might be about a different day or a different trading session. But the user's input specifies the trading period as intraday. This is a bit confusing. However, according to the instructions, I should use the provided stock performance data. So the movement is up 371.88% intraday. The news events mention similar surges in regular trading, which would be the same as intraday. Therefore, the relevant news is the one that mentions the stock surging in regular trading hours. The content of the news is about the stock surging with high turnover, which is likely due to increased trading activity. The summary should state that FAT Brands-B surged 371.88% intraday, aligning with the news reports of a surge in regular trading with high turnover. The cause is the surge in trading activity, possibly due to market speculation or other factors mentioned in the news, like "Operations too frequent." But the news content is limited. The first reason's content says "Operations too frequent. Try again later..." which might be a technical issue. The other reasons also have similar issues. However, the key is that the news reports the stock's surge, which is the main factor. So, the final summary would link the intraday surge to the reported surge in.
