Scienjoy shares surge 10.00% after-hours as 30.9% operating income growth and AI-driven strategy boost investor confidence.

think> Okay, let's start by understanding the user's request. They want me to act as a financial analyst explaining a stock's price movement based on recent news. The input includes the stock performance, trading period, and a detailed news event about Scienjoy Holding Corporation's financial report. First, I need to check the stock movement. The stock went up by 10.00440723% after hours. Rounding that to two decimal places gives 10.00%, and since there are trailing zeros, I should remove them, making it 10.00% or just 10%. Wait, the instruction says to round to two decimal places and remove trailing zeros. So 10.0044... becomes 10.00%, but trailing zeros are removed, so it's 10%. Hmm, maybe the correct way is to present it as 10.00% but then remove the trailing zeros, so it's 10%. Let me confirm. The example shows 4.230769% becomes 4.23%. So in this case, 10.00440723% would be 10.00%, but since after two decimal places it's 10.00, but trailing zeros can be removed, so it's 10%. Wait, maybe the example actually rounds to two decimal places and removes trailing zeros. For instance, 4.230769% becomes 4.23%, and 10.00440723% rounds to 10.00%, but trailing zeros are removed, so it's 10%. So the correct format here is 10.00% but written as 10.00%? Or is it 10%? The example shows 4.23% as the output. Let me check the example again. The input was 4.230769%, and the output was 4.23%. So in this case, the user wants to round to two decimal places, so 10.00440723% becomes 10.00%. But the instruction says to remove trailing zeros. Wait, the example's input was 4.230769% and the output is 4.23%. So in that case, they rounded to two decimal places. So here, 10.00440723% would be 10.00% when rounded to two decimal places. But the instruction says to remove trailing zeros. So if it's exactly 10.00%, then it would be written as 10.00% but with trailing zeros removed, so it's 10.00%? Wait, maybe the example is a bit conflicting. The example input is 4.230769% and output is 4.23%. So in that case, they rounded to two decimal places and kept the two decimal places. So perhaps the user wants to keep two decimal places even if they are zeros. Let me check the example again. The input is Pineapple Energy Inc.盘前 premarket大涨4.230769%. The output is "surged 4.23% in premarket trading". So the percentage is presented with two decimal places. Therefore, in this case, the input is 10.00440723%, which rounds to 10.00% when rounded to two decimal places. So the output should be 10.00%. But the instruction says to remove trailing zeros. Wait, the example shows 4.23% as the output. So perhaps the user wants to keep two decimal places regardless. So the correct approach here is to present 10.00% as the percentage. Next, the trading period is after-hour. So the stock moved up by 10.00% in after-hour trading. Now, the key news is the financial report. The company reported a 30.9% increase in income from operations despite a 5.3% revenue decrease. The CEO and CFO highlighted the improved gross margin and operational efficiency, as well as the expansion of AI initiatives. The CFO mentioned the resilience of the business strategy with a focus on global expansion and innovation. These positive factors likely led to the after-hours surge. The news is relevant, and the movement is bullish, aligning with the positive earnings and operational improvements. I need to make sure that the explanation is concise, under 150 words, and follows the example's structure. The example includes the stock movement, trading session, and the key news. The key here is the increase in operating income and the company's strategic initiatives.
