周一盘前，永利度假村（WYNN）股价大涨5.20%，引起投资者广泛关注。这一显著涨幅背后的原因值得深入探讨。
根据美国银行的最新报告，永利度假村成为内部人士买入比例最高的标普500成分股之一。数据显示，过去三个月内，永利度假村的内部人士买入比例高达0.53%，在所有标普500成分股中排名第一。这一数据远高于其他公司，如排名第二的阿波罗全球管理（APO）的0.15%和第三的西方石油（OXY）的0.11%。
美国银行股票与量化策略主管Savita Subramanian指出，内部人士的操作可被视为"最聪明的资金"。他解释道："自2010年以来，极端的内部买入/卖出成为更有效的逆向指标——内部人士倾向于在下跌时买入支撑股价，或在涨势初期抛售。"这一观点进一步强化了永利度假村内部人士大量买入的重要性，暗示公司高管对公司未来前景持乐观态度。投资者似乎对这一信号反应积极，推动股价在盘前显著上涨。
