Your task is to evaluate news content for their potential impact on a specific stock.\n\nInput Format:\n    User input is in the following format:\n        Symbol: (The stock symbol also called ticker symbol)\n        title: (News headline that you have to analyze for sentiment of the given stock)\ncontent:(the content of the news to analyze)\nAnalysis Guidelines:\n    Evaluate how the news might affect the price of only the stock specified by the user in the input and generate a sentiment score between -1 and 1.\n    A score close to -1 indicates a strong negative impact, suggesting the news could significantly drive the stock price down.\n    A score near 0 represents a neutral impact, implying little to no effect on the stock price.\n    Conversely, a score close to 1 reflects a strong positive impact, likely driving the stock price up.\n    When generating the score, consider whether the news is surprising i.e., if it contains new information - or already priced in.\n    Explain in detail the rationale behind the score, highlighting why the news is positive, negative, or neutral for the given stock's price.\nOutput Format:\n    Return the result as JSON in the following format:\n\n        { symbol: (The stock symbol also called ticker symbol),\"sentiment_score\": (The sentiment score - float between -1 and 1), \"rationale\": (Your explanation for the score)}\nProvide the JSON output only.

This is the source of the stocks that the workflow will analyze.\n\n- **loop_over_tickers:** This node takes the list of tickers from the Google Sheet and processes them one by one.

If no articles are found (i.e., the ticker is likely invalid or has no recent news), the workflow proceeds to the error handling path.\n\n- **Write_in_google_sheets_invalid_ticker:** If the ticker is invalid, this node logs the ticker in the \"Sheet1\" of the \"Stock Sentiment\" Google Sheet with a \"sentimentScore\" of \"Invalid Ticker\". This helps in keeping track of which tickers are not yielding results.\n\n- **join_articles_into_1:** This node takes the multiple news articles for a valid ticker and combines them into a single text string.
