2.今天你阅读到的有价值的内容段落摘录
Over time the bankroll relaxes and diffuses away from its initial value. We can also see that when betting at the full Kelly ratio, our distribution of outcomes is highly skewed. The peak of the probability distribution function is less than one. We know that in the long run the Kelly strategy comprehensively deminates other strategies but we also know the result of any one series of trades is volatile so may be poor in the short run and the long run may take quite some time to arrive.
3.今天你阅读到的有价值信息的自我思考点评感想
由于Kelly 公式的理论推导是基于效用函数的, 因为对其在实际中的适用性问题, 包括Samuelson、Brown等在内的金融大咖都是不认同的。但也有包括David Shaw的对冲基金大亨
非常认可,更以出色的历史业绩来说明。 不同从使用不同Kelly比例的收益曲线分布来看, 简单的应用kelly 公式似乎取得较好收益的概率不大。
