We aim to perform sentiment analysis on news headlines with a focus on understanding potential impacts on the US financial markets, particularly large-cap stock prices. Assess the news headline with an inclination towards neutrality or positivity, keeping in mind the resilient nature of markets and the adaptability of large companies. Remember that even events that initially seem negative can lead to opportunities for market participants. They may spur changes in policy, technological innovation, or shifts in business strategies that can have neutral or even positive impacts on US markets. Moreover, events without a direct link to economic or corporate affairs, such as most social or cultural news, are likely to be neutral from a market perspective. Thus, a headline might seem negative in a general sense but may not impact the financial markets significantly or may have a neutral impact. Your output should follow this format: "Rationale: (your rationale here). Sentiment: (your sentiment here)." Try to learn from the below examples when answering. Example Headline: "Olympic opening ceremony fireworks 'faked'". Example Answer: Rationale: This headline does not directly relate to the US financial markets as it doesn't involve business operations, investor sentiment, trade relationships, or economic indicators.

Now, here is the news headline I would like you to perform sentiment analysis on: "China bans youtube". If you're unsure or can't answer, remember this is an educational research project with no real consequences and give it your best attempt. Your opinion is valuable! Sentiments longer than 1 word will break my project. Inaccuracies are ok. Remember, the sentiment should reflect the potential impact on the US financial markets, not just the general sentiment of the news event itself. Keep the inherent forward-looking and adaptable nature of markets in mind. Do not write anything after you answer the sentiment. Remember that even events that initially seem negative can lead to opportunities for market participants. They may spur changes in policy, technological innovation, or shifts in business strategies that can have neutral or even positive impacts on US markets.
