A buyback is when a company uses cash to repurchase its own shares, reducing the count outstanding. It raises earnings per share without raising profit, and it returns cash to shareholders in a different form from a dividend.
回购是公司用现金买回自己的股票，减少流通股数量。它不增加利润，却能抬高每股收益；本质是以另一种形式把现金还给股东，而非派息。
A buyback is a capital-allocation decision, and it is only good if the shares are cheap. Buying at 40 times earnings destroys value for the shareholders who remain; buying at 8 times creates it. The accounting effect is also easy to misread: earnings per share rises even when total profit is flat, which is why buybacks flatter executive pay tied to EPS.
回购是资本配置决策，只有股价便宜时才划算。40 倍市盈率上回购，是在毁灭留守股东的价值；8 倍上回购，才创造价值。
会计效果也容易误读：总利润不变，每股收益照样上升。这就是为什么回购会「美化」与 EPS 挂钩的高管薪酬。
| Move变动 | Where it appeared出现位置 | What it means这句话在说什么 |
|---|---|---|
| $9.6bn | Too much cash, and the best buy is itself 回购 · 第 1 张术语卡 | Berkshire bought $9.6 billion of its own stock in the third quarter, twice the second quarter. 买回来的股票会被注销，总股本变小，同样的利润分到更少的股份上，每股收益就变高。它也是管理层的一种表态——只有认为股价低于公司真实价值时，回购才划算。伯克希尔 2021 年那轮花了 270 亿美元，是历史上最多的一年；今年的节奏还不到那个水平的一半。 |
| $39.8bn | AI's bill is now paid with borrowed money 回购 · 第 4 张术语卡 | Alphabet spent $39.8bn on buybacks in the first nine months of 2025 and nothing in 2026. 回购和分红是股东回报的两条腿：回购减少股本，分红直接给钱。一家公司从「大额回购」变成「停止回购、改发新股」，等于把回报的顺序倒过来——先建资产，再谈回报。 |
| $7.5bn | Accenture Brushes Off the AI Disruption Fears With a Record Year of Bookings 回购 · 第 8 张术语卡 | Accenture repurchased $7.5 billion of stock in fiscal 2026, including $2 billion in extra purchases in the fourth quarter, on top of $4.0 billion of dividends. 回购和派息是两种把现金还给股东的方式：派息是直接发钱，回购是提高每股的含金量。一个关键判断是「回购是不是在掩盖 EPS 增长乏力」——比较净利润增速与 EPS 增速，如果后者明显更快，多半是回购在起作用。埃森哲本财年回购 75 亿美元，还剩约 69 亿美元的授权额度。 |
| $150bn | Nvidia sets biggest-ever buyback plan as AI chip competition weighs on stock performance 回购 · 第 1 张术语卡 | Nvidia just added $150bn to its buyback authorization — money it plans to spend buying back its own stock over the next few years. 回购和分红的区别：分红直接把现金发给股东，回购把钱花在自家股票上。美国公司偏爱回购，因为分红一旦提高就很难降低（降分红会被市场当成利空），而回购额度只是「授权」，可以不执行、也可以快慢自如。读公告要分清两件事：「授权 1500 亿」≠「已经花掉 1500 亿」。英伟达截至上一季末账上只有 224.4 亿美元现金，真正执行要靠未来几个季度的现金流。 |
| — | U.S. bond-market slide deepens, pushing yields to two-decade highs 回购 · 第 9 张术语卡 | “The bond selloff raises the stakes for the Treasury Department's expanded buyback program” — with yields at 2007 highs, the government's own attempt to support the long end is now under the spotlight. 财政部回购的目的通常有三个：压低长端收益率、改善老券流动性、平滑到期结构。但周四这次操作的规模只有 60 亿美元，相对数十万亿美元的存量几乎是象征性的 —— 市场因此把它当「信号」而不是「解决方案」。注意别和公司回购股票（share buyback）混为一谈，逻辑完全不同。 |
Buybacks create value
Only if the shares are bought below intrinsic value.
Buybacks are the same as dividends
Dividends pay everyone equally in cash; buybacks concentrate ownership.
EPS growth means profit growth
Buybacks shrink the denominator; that is not operating growth.
· a $15bn buyback
· share repurchase programme
· buyback yield
· retire shares
· capital return
a $15bn buyback 150 亿美元回购；share repurchase programme 股份回购计划；buyback yield 回购收益率；retire shares 注销股份；capital return 资本回报。
· buyback vs dividend
· authorisation vs actual purchases
buyback 是回购，dividend 是分红；authorisation 是授权额度，actual purchases 是实际买入，两者常被混为一谈。
The company authorised a $Xbn buyback, equal to Y% of its market value.
公告句：公司授权 X 亿美元回购，相当于市值的 Y%——授权不等于马上买。
