Stock Fundamental Analysis
From Business Reality to Valuation股票基本面分析
从商业事实走向估值判断
Stock fundamental analysis evaluates the business behind a ticker—its economics, financial statements, cash generation, valuation, and risks—before forming a documented thesis.
股票基本面分析关注股票代码背后的企业：商业模式、财务报表、现金创造能力、估值与风险，并在证据基础上形成可复核的研究结论。
Stock fundamental analysis: the five-part framework股票基本面分析：五部分研究框架
The main search intent is practical and informational: readers want to know what to examine, which financial statements and ratios matter, how to compare a company with peers, and how to avoid turning one attractive metric into a buy signal. A complete review connects five evidence groups.
用户真正想解决的不是背诵指标，而是知道应该看什么、三大财务报表如何串联、哪些比率适用、怎样比较同行，以及如何避免把单一好看的数字误当成买入信号。完整分析应连接五组证据。
01
Business model商业模式
Identify customers, products, revenue drivers, unit economics, market structure, competitive advantages, and the conditions that could weaken them.
识别客户、产品、收入驱动、单位经济、市场结构、竞争优势及其可能失效的条件。
02
Financial performance财务表现
Trace revenue, margins, returns, working capital, leverage, and cash flow over several comparable periods.
在多个可比期间追踪营收、利润率、资本回报、营运资金、杠杆与现金流。
03
Earnings quality盈利质量
Reconcile accounting profit with operating cash flow and inspect accruals, stock compensation, capitalized costs, and one-time items.
把会计利润与经营现金流核对，并检查应计项目、股权激励、资本化成本和一次性项目。
04
Valuation估值
Compare price with normalized earnings, cash flow, assets, growth, and risk using more than one method.
用不止一种方法，把价格与标准化盈利、现金流、资产、增长和风险联系起来。
05
Risks and falsifiers风险与反证条件
State what would invalidate the thesis: demand loss, margin compression, refinancing pressure, dilution, regulation, or governance failures.
明确哪些事实会推翻研究假设，例如需求流失、利润率收缩、再融资压力、稀释、监管或治理问题。
How to analyze the three financial statements together如何联动分析三大财务报表
The income statement shows performance over a period, the balance sheet shows resources and obligations at a date, and the cash flow statement explains how cash changed. Their links matter more than any statement alone.
利润表反映一段期间的经营结果，资产负债表反映某个时点的资源与义务，现金流量表解释现金为何变化。报表之间的勾稽关系比单独查看任何一张表更重要。
Resilience and capital intensity韧性与资本密集度
Review liquidity, debt maturity, lease obligations, goodwill, inventory, receivables, and the capital required to sustain growth.
检查流动性、债务到期、租赁义务、商誉、存货、应收账款，以及维持增长所需资本。
Cash conversion and reinvestment现金转化与再投资
Reconcile net income to operating cash flow, distinguish maintenance from growth investment, and examine financing dependence.
把净利润与经营现金流核对，区分维持性投资与增长性投资，并观察企业对融资的依赖程度。
Key ratios for stock fundamental analysis股票基本面分析常用指标与比率
There is no universal “best” metric. Choose ratios that match the business model and compare them across time, peers, and accounting definitions.
不存在适用于所有公司的“最佳指标”。应根据商业模式选择指标，并统一期间、同行范围与会计定义。
Growth增长Revenue growth, organic growth, EPS growthAsk whether growth is repeatable and cash-generative.判断增长能否重复并转化为现金。
Profitability盈利能力Gross margin, operating margin, ROIC, ROEUse the right denominator and explain leverage.选择正确分母并解释杠杆作用。
Financial health财务健康Net debt, current ratio, interest coverageMap maturities and liquidity, not just headline debt.不仅看债务总额，还要看期限与流动性。
Valuation估值P/E, EV/EBITDA, P/S, FCF yieldNormalize earnings and compare like with like.标准化盈利，并确保同口径比较。
Worked example: turning metrics into a research question示例：把指标转化为研究问题
Assume a fictional company reports 12% revenue growth, an operating margin rising from 14% to 16%, net debt falling, and free cash flow below net income. The first three facts look constructive, but the cash gap requires investigation. Was working capital absorbed by temporary inventory, were receivables stretched, or were costs capitalized? The example shows why a stock fundamental analysis checklist should create questions, not automatic scores.
假设一家虚构公司营收增长12%，营业利润率从14%升至16%，净债务下降，但自由现金流低于净利润。前三项看似积极，现金差距却需要追查：是临时备货占用营运资金、应收账款周期延长，还是部分成本被资本化？这个例子说明，股票基本面分析清单应产生可验证的问题，而不是自动给出分数。
Teaching example only.仅为教学示例。 No company, price target, expected return, or recommendation is implied.不对应真实公司、目标价、预期收益或投资建议。
Valuation: price is part of the fundamental question估值：价格也是基本面问题的一部分
A good business can be a poor investment at an unsupported price, while a low multiple can reflect real deterioration. Use relative valuation to understand market context and an intrinsic-value model to make assumptions explicit. Test revenue, margin, reinvestment, discount-rate, and terminal assumptions as ranges rather than one precise target.
好公司在缺乏支撑的价格下也可能不是好投资，低估值倍数也可能反映真实恶化。相对估值用于理解市场背景，内在价值模型用于把假设写清楚。营收、利润率、再投资、折现率和终值都应采用区间与情景，而不是伪精确的单点目标价。
