图1偏股基金 · 滚动年化收益率
① 四条线都基于 中证偏股基金指数（930950.CSI），净值口径、分红已含。
② 横轴是买入月份：一个点＝在这个月买入、持有满 N 年后的年化收益率（先算这 N 年的累计涨幅，再开 N 次方）。例如 3 年线在 2023-08 的点＝2023-08 买入、2026-08 卖出，三年共涨 36.24%，年化 10.86%。
③ 四条线右端依次断开 —— 是那之后买入的还没满 N 年，不是数据缺失；灰色淡影＝国证A指点位（右轴），两轴各自缩放，不能跨轴比高度。

图2偏股基金 · 滚动累计收益率
① 与图1 同一批窗口、同一个指数；这里画的是累计涨幅本身（不开 N 次方），回答「这 N 年一共赚了多少」：3 年线在 2023-08 的点＝+36.24%，就是 2023-08 买入、三年后一共赚 36.24%。
② 与图1 是同一批窗口的两种算法，不要跨图比高低：10 年累计天然比 3 年大，不代表更划算 —— 要比「每年多少」请看图1。

① 每行＝一个买入月份，列出持满 3 / 5 / 7 / 10 年的累计与年化（%）。
② 空格＝这个月买入后还没满那么久，不是缺失、也没有被插值：5 年从 2021-09 起空、7 年从 2019-09、10 年从 2016-09；表只列到 2023-08（最后一个「已经能满 3 年」的买入月），再往后四组全是空格。

数据口径说明
数据来源：中证偏股基金指数（930950.CSI）与国证A指（399317.SZ）的月K序列，取自万得（Wind）Alice MCP 的指数行情接口。月频，每月取该月最后一个交易日；当月没走完的月份整月剔除，不外推。数据截止 2026-08（2026-09 当月未走完，已剔除）。
主指数：中证偏股基金指数（净值加权编制），分红已反映在净值里，可直接当持有收益看。
背景指数：国证A指同为全收益指数、含分红 —— 与 930950 口径一致，可以直接对照。
滚动窗口：N 年窗口＝「买入月之后第 N 年的同月末点位 ÷ 买入月点位 − 1」。本页共 225 个数据月，3 / 5 / 7 / 10 年分别能算出 189 / 165 / 141 / 105 个窗口。年化＝(1 + 累计)^(1÷N) − 1，含复利。
留空：不满 N 年的区间一律留空，不插值、不外推。
样本重叠：滚动窗口逐月滑动、高度重叠，统计值只描述历史分布，不能当独立概率用。
