■记者观察 健康，是投资最大的"本金" ◎记者赵明超 过去一周，泉果基金创始人王国斌离去的消息令人扼腕叹息。他是国内最早倡导并推动价值投资的投资 人之一，在业内备受尊敬。得知他离去的消息后，很多基金经理表示震惊和难过。 "身体是最大的本钱"，这句话是常识。对于很多为了生活而奔波的人来说，有时候不得不牺牲身体健康 去挣钱养家，这句话似乎是"何不食肉糜"。但在投资领域，身体健康是最大的本钱，却有着最实在的意 义。 先说复利为什么至关重要。从人类经济发展历程看，在传统农业社会，土地是核心生产要素，任何短暂 的技术进步带来的粮食增产，很快会导致人口增加，最终人均资源占有量和生活水平又被拉回到仅能维 持生存的"生存线"附近，形成了"马尔萨斯陷阱"。 有人研究了巴菲特的财富增长路径，得出的结论是如果他在60岁的时候停止投资，那么他的资产只能有 现在的1%。也就是说，巴菲特99%的财富都是在60岁以后获得的，对于如今95岁高龄的巴菲特来说， 长寿无疑是他跻身全球最富有的人之一的重要原因。 "长寿"这两个字，对应到投资里就是时间足够长。对于投资而言，复利是最重要的特征之一，尤其是在 现代工业革命之后，复利已经成为主导性的经济 ...

1/5 慢慢变富 今天在后台看到一个对"慢慢变富"这个观点的评论： 唉，其实每次我提到"复利"，提到"慢慢变富"，都有人这么说。很多人就算嘴上不说，心里也会想：如果人生大部分时间根本享受不到自己赚到的钱，这 样的投资方法有什么意义呢？ 2/5 实际上，这个感受首先是大家对巴菲特的一个误解——老爷子99.8%的财富在50岁后获得。 这个数据没错，但你把这个财富积累结构套在自己身上就错了。 第一、老爷子实在太高寿了，今年都95了，他从26岁开始创办自己的投资公司，大部分人50岁之后就是半退休状态，可老爷子50岁以后的投资生命接近之 前的两倍。现加上50~70岁是巴菲特投资生涯中收益率最高的阶段，才出现了99.8%这么夸张的结构。 第二、老爷子的收益率太高了，一般人根本远远达不到。 复利积累的财富中，后期占比跟收益率有很大的关系。以定投为例，从25岁开始定投40年，一般人"慢慢变富"的年化收益率8%，65岁的资产总额大约是 45岁资产总额的 5.92倍，而股神的"慢慢变富"的年化收益率20%，65岁的资产总额大约是45岁资产总额的 51.35倍。 对于普通人6%~10%的收益率而言，通过20-30年的积累，在60岁 ...
