n.[U][C]
1. 思索;沉思;推测[(+about/on/upon)]
There has been a great deal of speculation about the Prime Minister's resignation.
最近有关首相辞职的臆测颇多。
2. 投机;投机买卖[(+in)]
His speculations in stocks led to his suicide.
他在股票上做投机买卖致使他自杀。

M&A = merger and acqusition = 并购
speculation = 投机

我猜是股票市场一些投机性买卖某些有机会被并购的公司，从而，很快赚取差价。
