Control Stock，控制股，控制股是指上市公司的主要股东所拥有的股权。这些股东要么拥有大部分已发行股票，要么拥有足以让他们对公司决策施加控制性影响的部分股票。

当公司拥有一种以上的普通股（common stock）时，相对于投票权较低的股票，具有较高投票权或投票权权重的股票被认为是控制股。

英文释义：Control stock refers to equity shares owned by major shareholders of a publicly traded company. Shareholders who control a majority of a company's shares effectively have enough voting power to dictate the firm's decisions. As such, their shares can be referred to as control stock.
