这当然不足以促使投资者对自己的投资组合作出任何重大调整。但有分析师表示,投资者如果能够规避那些历来习惯在九月下跌的股票,就可能获利。
Since 1926, in any given month, stocks of large companies have risen 0.9% on average, according to Bank of America Merrill Lynch. But in September, they have fallen by 0.8%, the only month with a negative average return.
据美银美林(Bank of America Merrill Lynch)统计,自1926年以来的任意月份,大盘股平均上涨0.9%,但唯有九月其平均表现是下跌的,这个月大盘股平均下跌0.8%。
'For whatever reason, there's a predictable pattern where September has bad performance,' says Steven DeSanctis a strategist with Bank of America Merrill Lynch's equity research team.
美银美林股票研究团队的策略师史蒂文・德森提斯(Steven DeSanctis)表示,不论出于何种原因,九月美股表现差已经有定式可循。
The trend has baffled researchers for decades. Striking September events, such as the 2008 collapse of Lehman Bros. and the 2001 terrorist attacks, are partly responsible for the bad average, but they can't explain the problems entirely.
这种定式已经困扰了研究人员数十年。一些“碰巧”发生在九月份的大事件,例如2008年的雷曼兄弟(Lehman Bros)倒闭、2001年的恐怖袭击,与股市在九月份糟糕的平均表现不无关系,但即便如此,也无法完整地解释这个现象。
