Kelly仓位计算
使用Kelly公式计算最优投资仓位,平衡长期增长与风险控制。
核心公式
完整Kelly: f* = (bp - q) / b
b= 盈亏比 (平均盈利/平均亏损)p= 胜率,q= 败率 (1-p)f*= 最优仓位比例
简化Kelly: f = μ / σ² (基于期望收益μ和方差σ²)
实践建议
- 分数Kelly: 使用1/4或1/2 Kelly降低波动
- 仓位上限: 单只股票≤25%(Munger原则)
- 最小仓位: Kelly<2%时不建仓
- 组合管理: 多只股票时需归一化总仓位
使用方式
当用户提供胜率和盈亏比时,计算完整Kelly并应用1/4分数:
let kelly = (b * p - (1.0 - p)) / b;
let safe_kelly = (kelly * 0.25).min(0.25).max(0.0);输出内容
- Kelly最优仓位
- 推荐仓位(1/4或1/2 Kelly)
