Learn fundamental analysis: financial statements, key valuation ratios, earnings analysis, DCF models, and how to use Diplyzer's AI agent to assess company financial health and intrinsic value.
Fundamental analysis answers the question technical analysis cannot: Is this company worth owning? While technical analysis tells you when to trade, fundamental analysis tells you what to trade. Together, they form the complete investor's toolkit.
At its core, fundamental analysis is the process of evaluating a company's true economic value by examining its financial statements, business model, competitive position, management quality, and growth prospects. The goal: determine whether the current market price is a bargain, a fair deal, or an overpriced risk.
The Fundamental Analyst's Toolkit
Fundamental analysis answers three core questions:
Is the business healthy? — Can it survive shocks, pay its debts, and generate consistent cash flow?
Is the business growing? — Are revenues, earnings, and margins expanding or contracting?
Is the stock fairly priced? — Does the current market price reflect the company's true intrinsic value, or is it significantly under or overvalued?
Diplyzer gives you instant access to all three dimensions for any publicly traded company.
Reading Financial Statements
Financial statements are the foundation of all fundamental analysis. There are three core documents:
The Income Statement
The income statement shows what a company earned and spent over a period (quarter or year). It flows from revenue at the top to net income (profit) at the bottom.
Key lines to examine:
Revenue — Total sales. Is it growing?
Gross Profit — Revenue minus direct cost of goods. Measures production efficiency.
Operating Income (EBIT) — Gross profit minus operating expenses. Core business profitability.
Net Income — The bottom line: what's left after all expenses, interest, and taxes.
EPS (Earnings Per Share) — Net income divided by outstanding shares. The most widely quoted profitability metric.
Often considered the most reliable financial statement because it is harder to manipulate than earnings. It shows the actual cash movement into and out of the business.
Three sections:
Operating Cash Flow — Cash generated by core business operations. Should consistently exceed net income in a healthy business.
Investing Cash Flow — Capital expenditures (capex) and asset investments. Negative is often healthy (investing in growth).
Free Cash Flow (FCF) = Operating Cash Flow − Capital Expenditures. This is the "real" profit available to reward shareholders or reinvest in the business.

Financial ratios allow you to compare companies of different sizes and across different industries. Diplyzer provides access to over 100 financial ratios for any company.
Valuation Ratios
Price-to-Earnings (P/E) Ratio The most widely used valuation metric. Price per share divided by annual earnings per share.
Low P/E — Potentially undervalued, or the market expects slow growth
High P/E — Market expects strong growth, or the stock is overvalued
Always compare P/E to the company's historical average, its sector peers, and the broader market index.
AI Prompt
"What is [company]'s current P/E ratio? How does it compare to its 5-year historical average and its sector median?"
Price-to-Sales (P/S) Ratio Useful for companies that are not yet profitable. Price divided by annual revenue per share. Particularly relevant for high-growth tech and biotech companies.
EV/EBITDA Enterprise Value divided by EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization). A capital-structure neutral valuation metric — accounts for debt levels. More comparable across companies with different debt loads than P/E.
AI Prompt
"What is [company]'s EV/EBITDA? How does it compare to sector peers?"
Price-to-Book (P/B) Ratio Price per share divided by book value per share. A value of below 1.0 means the market is pricing the company below its accounting value — historically associated with undervaluation in cyclical and financial companies.
Graham Number Benjamin Graham's formula for the maximum fair value of a stock: √(22.5 × EPS × Book Value Per Share). Any stock trading below its Graham Number is considered deeply undervalued.
AI Prompt
"Calculate the Graham Number for [company] and compare it to the current price."
Return on Equity (ROE) Net income divided by shareholders' equity. Measures how efficiently management uses shareholder capital to generate profit. Warren Buffett's benchmark: consistent ROE above 15%.
Return on Invested Capital (ROIC) Net operating profit divided by total invested capital. Considered a more comprehensive measure than ROE because it includes both equity and debt capital. ROIC consistently above the cost of capital = economic value creation.
Operating Margin Operating income divided by revenue. The percentage of each revenue dollar that becomes operating profit. Higher margins indicate stronger pricing power and cost efficiency.
AI Prompt
"What are [company]'s ROE, ROIC, and operating margins? How have they trended over the past 5 years?"
Current Ratio Current assets divided by current liabilities. Measures ability to cover short-term obligations. A ratio above 1.5 is generally considered healthy.
Debt-to-Equity Ratio Total debt divided by shareholders' equity. High ratios indicate more financial leverage and risk, especially if the business generates lumpy cash flows.
Interest Coverage Ratio EBIT divided by interest expense. Measures how many times over the company can pay its interest from operating profit. Below 2× is concerning.
AI Prompt
"Assess [company]'s financial health. Show me the current ratio, debt-to-equity, and interest coverage."
The DCF model values a company based on the present value of all its expected future cash flows, discounted back at an appropriate rate (the weighted average cost of capital, or WACC).
The core equation: the business is worth the sum of all future cash flows it will generate, adjusted for the time value of money. A company generating $1 billion in free cash flow this year, growing at 10% annually, is worth far more than a company generating the same cash flow with zero growth.
DCF is the most theoretically sound valuation approach, but it is sensitive to input assumptions — small changes in growth rate or discount rate can dramatically change the output.
AI Prompt
"Run a DCF valuation on [company]. What is the implied intrinsic value vs. the current market price?"
Warren Buffett defines a company's true earnings power through "owner earnings":
Owner Earnings = Net Income + Depreciation/Amortization − Maintenance Capex
This strips out non-cash charges and adjusts for the capital required to maintain the business, revealing the true cash profits available to the owner.
AI Prompt
"Calculate owner earnings for [company] over the last 3 years. Compare to reported net income."
Even the best fundamental analysis benefits from knowing what professional Wall Street analysts think.
Price Targets and Consensus
Hundreds of analysts at major investment banks model companies full-time. Their aggregate view — the consensus price target — provides a useful benchmark:
Buy consensus with low current price — Significant upside potential recognized by professionals
Sell consensus — Broad professional agreement that the stock is overvalued
Divergence from consensus — The best opportunities often exist where an informed minority disagrees with the crowd
AI Prompt
"What is the analyst consensus for [company]? What is the average price target and how far is it from the current price?"
Markets are largely driven by surprise. A company that consistently beats earnings estimates tends to be rewarded with upward revisions. A company that consistently misses tends to be punished.
Earnings Surprise: The percentage difference between actual EPS and the consensus estimate. Consistent positive surprises ("beats") are one of the strongest indicators of fundamental momentum.
AI Prompt
"Show me [company]'s last 8 quarters of earnings. Did they beat or miss EPS and revenue estimates each quarter? What was the surprise percentage?"
Environmental, Social, and Governance (ESG) ratings have become increasingly important for institutional allocation decisions. Poor ESG scores can expose a company to regulatory risk, reputational damage, and eventual capital outflows from ESG-mandated funds.
AI Prompt
"What is [company]'s ESG risk rating and how does it compare to its industry peers?"
Misaligned executive compensation is one of the clearest red flags in fundamental analysis. When executives are paid enormous salaries regardless of performance, or when their incentives don't align with shareholder value creation, it often predicts poor long-term outcomes.
AI Prompt
"Show me [company] CEO's compensation breakdown for the last 3 years. How does it compare to the company's profitability growth?"
A strong fundamental analysis typically synthesizes:
Revenue quality and growth — Is growth sustainable and high-quality?
Profitability and margins — Are margins expanding or contracting?
Financial health — Can the company survive adversity? (Z-Score, F-Score, debt ratios)
Valuation — Is the price justified by the fundamentals? (P/E, EV/EBITDA, DCF)
Growth prospects — What are analysts expecting? What is the earnings trajectory?
Management quality — Are insiders buying or selling? Is compensation aligned?
Ask Diplyzer for a complete fundamental analysis:
AI Prompt
"Give me a comprehensive fundamental analysis of [company]. Include the key valuation ratios, growth metrics, financial health scores, analyst consensus, and DCF intrinsic value estimate."
The best trades combine fundamental conviction with technical precision:
What to buy (or sell short) — Determined by fundamental analysis
When to buy (or sell) — Determined by technical analysis
A fundamentally strong company trading at a discount to intrinsic value, in a technical support zone, with an RSI at oversold levels, and a bullish SMC order block nearby — that is the complete setup.
AI Prompt
"I believe [company] is fundamentally undervalued based on its DCF. Can you show me the technical chart and identify the best entry zones using support levels and Smart Money Concepts?"
How often should I review a company's fundamentals? Financial statements are released quarterly. Review them each time a company reports. Also review annually when the 10-K filing is published — it contains the most detailed and audited information.
What industries require different valuation approaches? Yes. Banks and financial companies are best valued using P/B and ROE. High-growth tech companies are often valued on revenue multiples (P/S, EV/Sales) or DCF with high growth assumptions. Capital-intensive companies (utilities, energy) are better evaluated on EV/EBITDA or dividend yield.
Can Diplyzer analyze international stocks? Yes. Diplyzer covers international equities across major global exchanges including London (LSE), Toronto (TSX), Sydney (ASX), Hong Kong (HKSE), Tokyo (JPX), and Indian exchanges (BSE, NSE).
