关于skewness：A positively skewed investment return m

关于skewness：A positively skewed investment return means there were frequent small losses and a few large gains. Negatively skewed means there were frequent small gains and a few large losses.
想问下这句话要如何理解呢？如有一个分布是右偏的但全部在纵轴的右侧，这个不就是不成立了吗？

投资回报率的正偏意味着经常出现小的损失和一些大的收益。负偏意味着经常有小的收益和一些大的损失。
