What is FAST Graphs?

FAST stands for Fundamentals Analyzer Software Tool. The idea behind it is simple and powerful: over the long run, a stock's price follows its earnings. FAST Graphs charts that relationship for any stock, so you can see whether today's price is running ahead of the business or lagging behind it.

The tool has been around for more than a decade, and its founder still records videos walking through viewer-requested stocks every week. That track record and transparency are a big part of its appeal.

What FAST Graphs does well

• One chart that tells the story. The orange fair-value line shows what the company's earnings justify. When the price sits above it, the stock is expensive. When it sits below, it's cheap. You can read it at a glance.
• Deep history. Up to 20 years of annual and quarterly data, with valuation history for each company, so you see how a stock has been priced across full market cycles, not just today.
• Many ways to measure earnings. Adjusted earnings, operating cash flow, FFO for REITs, free cash flow, EBITDA, and sales, so the valuation fits the kind of business you're looking at.
• Forecasting with analyst estimates. A calculator projects future returns from analyst forecasts, and FAST Graphs tracks how accurate those analysts have been on each company, which very few tools do.
• FG Score. A single score that sums up a company's fundamental quality, with peer comparisons.
• Screens and portfolios. Prebuilt screens, custom screens on Premium, and portfolios that connect to your broker so you can see how your holdings are valued.
• An AI assistant. "Charles" answers questions about any company in plain English and can build screens and review portfolios (Premium plan).
• Broad coverage. Around 18,000 stocks worldwide.

Where FAST Graphs comes up short

• It's a valuation lens, not a research process. FAST Graphs is superb at "is the price reasonable?" It does much less to answer "is this a business I should own, and why?" The qualitative work (the business model, the moat, management) is up to you.
• Growth stocks often look expensive. An earnings-based fair value works best for steady, profitable companies. Fast growers that reinvest heavily, or that aren't profitable yet, can look permanently overvalued even when the business is excellent.
• It assumes you know how to read it. The chart is simple once you understand it, but the tool does little to teach a newer investor what to look for or why it matters.
• No lifecycle awareness. A young growth company and a mature dividend payer are viewed through the same earnings-multiple lens.
• No free plan. There's a 7-day free trial, then a paid plan. Reviewers also note logins are limited to one device at a time and subscriptions aren't refundable.

What is Stock Simplifier?

Stock Simplifier is an AI-powered stock research tool built to help you actually understand a company and build conviction you can hold through volatility. Every data point is real, sourced from Fiscal.ai, an institutional-grade financial data provider, and updated the moment a company reports. Instead of handing you a single chart, it walks you through the whole business.

The framework was built by studying how the world's greatest investors (Warren Buffett, Peter Lynch, Terry Smith, David Gardner, Nassim Taleb, and others) actually make decisions, then turning that into a simple, repeatable workflow that runs in about 60 seconds and teaches you as you go.

What Stock Simplifier does well

• Builds real conviction, not just a valuation. Every stock goes through the same plain-English framework: Business, Moat (with moat direction), Management, Growth, Risk, and Valuation. That's the understanding that lets you hold through a 30% drawdown instead of panic-selling.
• Works for growth stocks too. A five-method valuation suite (Trailing Multiples, a Deep-Dive valuation, TAM-based sizing, a forward DCF, and a Reverse DCF that shows what growth the current price already assumes) gives fast growers a fair hearing instead of judging them only on today's earnings.
• Phase-aware analysis. Stock Simplifier identifies where a company sits in its lifecycle and adjusts what matters. A hyper-growth company and a mature dividend payer are evaluated on different criteria. The Phase checker is free to try.
• A complete financials module. Ten-plus years of income statement, balance sheet, and cash flow, with a "Simplify" view that curates the metrics that actually matter, plus daily charts for every ratio and yield.
• Dividend safety, earnings, and watch flags. A transparent 0–5 dividend safety score, trailing quarters of actual results versus the AI's prior estimates, and plain-English green/red flags to watch for each stock.
• Discover screener. Screen on real AI assessments (moat, management, phase, difficulty) as well as the numbers.
• Teaches you as you use it. Education is built into every step. Click any info icon to understand a metric instantly. You don't need to already be a value investor.
• Free to start. A free plan with no credit card, and paid plans with a free trial and a 30-day money-back guarantee.

Where Stock Simplifier falls short vs FAST Graphs

• No single signature valuation chart. FAST Graphs' earnings-vs-price chart is a uniquely fast way to see valuation across 20 years. Stock Simplifier spreads valuation across several methods instead.
• Less history on valuation. FAST Graphs goes back further on how a stock has been priced across cycles.
• No analyst-accuracy tracking or broker-connected portfolios. Both are genuinely useful FAST Graphs features we don't offer.
• Narrower coverage. Stock Simplifier covers 10,000+ global stocks versus FAST Graphs' roughly 18,000.
