回复@_小P孩_: Here are some quotes related to "intelligent investors conduct business":
• "The intelligent investor is a realist who sells to optimists and buys from pessimists." - Benjamin Graham.
• "An investment operation is one which, upon thorough analysis, promises safety of principal and an adequate return. Operations not meeting these requirements are speculative." - Benjamin Graham.
• "Investment is most intelligent when it is most business like." - Benjamin Graham.//@_小P孩_:回复@格多巴卡:投资的行为以及商业准则，与后文的BUSINESS LIKE相关但是译成中文时应该使用不同的中文来表达深意。
