mean 表示“意味着”，后接名词作宾语，若跟动词，应使用动名词。正确表达应为：

Asset allocation means spreading your funds over various types of assets.

网友提供的句子属于不规范的表达，起码是标点符号不能正确使用。

如果直接使用动词不定式，应该加引号，让不定式表示名词概念。

Asset allocation means "spread your funds over various types of assets".

Asset allocation means "to spread your funds over various types of assets".
