J-Long Group shares rise 13.66% intraday following a stock repurchase plan and 19.3% revenue growth.

think> Okay, let's tackle this query. The user wants me to transform a given Chinese text into a concise news headline following specific rules. First, I need to make sure I understand all the requirements. The input is about J-Long Group's stock surging intraday by 13.65935919%. The user provided two key points: the company announced a stock buyback plan on September 15, 2025, allowing up to $5 million in repurchases over six months to reduce shares. Also, for the six months ending September 30, 2025, revenue increased 19.3% to $22,699,837. The rules are to keep the company name as is, round the percentage to two decimals (so 13.66%), include the time period (intraday), and give a brief reason for the price movement. The example uses a structure where the headline starts with the company name, the percentage change, time period, and the reason. The example also includes additional details in the next paragraph, but the user wants a headline, so maybe I should keep it concise but include the main points. Wait, the example has two paragraphs. The first is the headline, and the second is more details. But the user says "transform the following text into a concise news headline," so maybe just the headline part is needed. However, looking at the example output, it's actually a paragraph, not a single headline line. The example output includes both the headline and additional details. So perhaps the user expects a similar structure: a concise summary with the company name, percentage, time period, and reason, followed by more details if necessary. But the user's instruction says "transform the following text into a concise news headline," which might imply a single headline line. However, the example given is a paragraph. Maybe the user is using the term "headline" more broadly to mean a summary that includes the required elements. Let me check the example again. In the example input, the output is a paragraph starting with the company name, the surge percentage, the time period, the reason (SunAtion subsidiary's project), and then more details about the company. So the user's example combines a headline with additional information. Therefore, I should follow that structure. So for the current input, I need to start with J-Long Group, the percentage (13.66%), intraday, then the reasons: stock buyback plan and revenue growth. The example includes two points in the reason, so I should mention both. Let me structure it as: "J-Long Group surged 13.66% intraday, driven by the announcement of a $5 million stock buyback plan to reduce shares and a 19.3% year-over-year revenue increase to $22.6 million for the six months ending September 30, 2025." Wait, the user's example includes the exact date for the buyback announcement (September 15, 2025) and the revenue period (six months ending September 30, 2025). Should I include those dates? The example includes the dates in the reason part. So maybe I should include them here as well. Also, the revenue figure is $22,699,837. Should I round that to $22.7 million or keep it as $22.7 million? The example in the input uses the exact figure, but the user's example output says "$22,699,837". Wait, in the example input, the revenue is 22,699,837, and the output says "22,699,837 dollars". But the user's instruction says to retain key information. So I should keep the exact figure. However, in the example output, the number is written with commas as $22,699,837. So I should present it similarly. Putting it all together: the headline starts with the company name, the percentage, time period, and the two reasons (buyback plan and revenue growth). The buyback plan is announced on September 15, 2025, and the revenue growth is for the six months ending September 30, 2025. So the final headline would be: "J-Long Group surged 13.66% intraday, driven by the announcement of a $5 million stock buyback plan to reduce shares and a 19.3% year-over-year revenue increase to $22,699,837 for the six months ending September 30, 2025." I need to check if all elements are included: company name, percentage rounded to two decimals (13.66%), time period.
