绿城中国（03900）今日盘中大跌5.10%，引发市场关注。该股价下跌可能与南向资金的减持行为有关。
根据最新数据显示，3月20日，南向资金减持绿城中国633.00万股。截至当日收盘，港股通共持有绿城中国55157.63万股，占流通股21.76%。这一减持行为可能对股价产生了负面影响，导致今日的大幅下跌。
值得注意的是，绿城中国近期表现曾较为强劲。数据显示，该股近5个交易日曾上涨7.73%，港股通累计增持222.50万股；近20个交易日更是上涨35.57%。然而，在此期间港股通累计减持719.32万股，显示出资金流向的变化。投资者应密切关注后续资金动向及公司基本面变化，以评估其对股价的潜在影响。
