What it does

AI Berkshire skill: 组合管理:从\"研究公司\"到\"管理组合\". Source: skills/portfolio-review.md.

Codex adapter note

This skill is generated from skills/portfolio-review.md so Claude Code and Codex users share one canonical workflow.

  • Treat $ARGUMENTS as the user's request in the current Codex thread.
  • When the source mentions Claude-only surfaces such as Task, Agent, WebSearch, Bash, Read, or Write, use the closest Codex capability available in this session: subagents when available, web search when needed, shell commands for local tools, and normal file edits for workspace files.
  • Use shared project tools from tools/ in this repository. Prefer running commands from the repository root with paths like python3 tools/financial_rigor.py ...; if the current thread starts outside the repo, locate the actual checkout path first instead of assuming a fixed home-directory path.
  • Before starting research, run the date command to confirm today's date; treat it as the baseline for "latest" data and state the data cutoff date in the report header. Never assume the current date from training data.
  • Preserve the research quality rules from AGENTS.md: cross-check financial data, use exact arithmetic tools for valuation/math, and clearly label uncertainty and source gaps.

组合管理:从"研究公司"到"管理组合"

对 $ARGUMENTS 执行投资组合审视与优化。

支持输入格式:

  • 持仓清单,例如:腾讯30%, 美团20%, 茅台20%, 英伟达15%, 现金15%
  • 或:腾讯 500股 @480港元, 美团 1000股 @130港元, ...
  • 或:我的持仓(如果已有保存的组合文件 reports/portfolio-latest.md)

"分散投资是对无知的保护。如果你知道自己在做什么,分散投资就没有意义。", , 巴菲特

"我这辈子见过的真正好的投资机会,十个手指就数得完。", , 李录

设计理念

研究公司只是投资的一半。另一半是组合层面的决策:

  • 买多少?(仓位)
  • 用什么钱买?(资金来源, , 新钱还是换仓)
  • 和已有持仓是否冲突?(相关性)
  • 最优组合长什么样?(机会成本)

巴菲特从不孤立地看一只股票, , 他总是在想"这是不是我能做的最好的事?"

执行流程

第一步:解析持仓

从输入中解析出当前持仓,标准化为以下格式:

标的代码持仓量成本价现价市值占比盈亏

如果输入只有比例没有金额,按比例分析即可。

同时检查是否存在已有的组合文件(reports/portfolio-latest.md),如有则读取并更新。

第二步:获取最新数据
