【帖子标题】：Burry’s Tragic Algebra: the NASDAQ-100 keeps 83 cents of every reported dollar, and break-even is 87%
【标题翻译】：巴里的悲剧性代数：纳斯达克100指数每报告1美元实际留存83美分，盈亏平衡点为87%
【帖子正文】：
Burry’s recent work swaps the GAAP stock-comp charge for what shareholders actually lose. The formula is Ω = C + V. V is the market value of shares delivered to employees, C is withholding tax net of option proceeds. Owners’ earnings are N + G − Ω, and ΔE is how much of reported profit survives.
【正文翻译】：巴里近期研究用股东实际损失替代了GAAP股票薪酬费用。公式为Ω = C + V。V是授予员工股票的市场价值，C是期权收益净扣缴税款。所有者盈利为N + G − Ω，ΔE则代表报告利润的实际留存比例。
The problem is V = T·(W+ΔS)/W. It needs W, the shares repurchased, which almost no company tags in XBRL. But P = T/W, so the W terms cancel:
【翻译】：问题在于V = T·(W+ΔS)/W。该公式需要股票回购量W，但几乎没有公司在XBRL中标注此项。由于P = T/W，W项可被抵消：
V = T + P·ΔS
You only need the average share price. That is what makes it automatable. The identity is exact. For P the tool uses the year’s average market price, which is how his later write-ups define it and what he uses for companies with no buyback; in his NASDAQ-100 study he used the buyback program’s own average price where there was one, and the two differ a little. On Salesforce that difference is worth about four points of ΔE, see below.
【翻译】：只需知道股票均价即可实现自动化计算。该工具采用年度平均市价作为P值——这正是巴里后期文章的定义标准，也是他对无回购公司的处理方式；在纳斯达克100研究中，他优先采用回购计划自身均价（若存在），两者略有差异。以Salesforce为例，该差异导致ΔE相差约4个百分点（见下文）。
I built it against SEC EDGAR and checked it against his numbers. Alphabet’s V matches all ten published years to the dollar. Pooled ΔE comes out 88.68% against his 88.7%, Meta 83.35% against 83.35%, the NASDAQ-100 overstatement 19.77% against 19.78%. There is a self-test button in the sidebar that runs those checks and a few hundred others.
【翻译】：我基于SEC EDGAR系统构建该工具并与巴里数据核对。Alphabet的V值与其十年公布数据完全吻合。汇总ΔE结果为88.68%（巴里数据88.7%），Meta 83.35%（完全一致），纳斯达克100高估率19.77%（巴里19.78%）。侧边栏设有自检按钮可运行数百项此类核查。
