AI打造持股法說會Telegram通知：告別錯過重要資訊的投資困境

台灣上市/櫃公司舉辦法說會，可提供投資人最新的公司營運資訊以及未來展望，即便佛系持股也不應該偏廢，過往由於資訊片斷化和自己的懶散常常漏掉持股公司的法說會消息，前幾天利用AI透過「開規格」的對話方式開發「持股法說會Telegram通知」小工具，利用Telegram(即時通訊工具)將個人持股和當天有舉辦法說會的資訊推播給自己，不漏掉關注公司的法說會消息，試行幾天體感覺得方便。

功能：從 Yahoo 奇摩股市台股法說會行事曆中抓取今日活動，
      並比對與使用者 portfolio (股票代號) 是否有匹配，
      若有則發送 Telegram 訊息通知「今天有開法說會」
      
使用方法：
    python script.py portfolio.cfg

portfolio.cfg 範例如下：
    5871 中租-KY
