STKtracker is a fundamental analysis platform for stocks and ETFs. It automatically gathers price, fundamental, insider-buying and analyst-consensus data, and assigns 4 proprietary scoring indices (ISF, ICF, ICE, IST) plus 9 automatic badges so you can compare stocks at a glance.

How is STKtracker different from a stock screener?

A screener filters stocks by static criteria. STKtracker also analyzes, scores and classifies each stock with a multi-factor composite, and organizes that information (scoring indices, badges, fundamentals and insider activity) in one place so you can make your own investment decisions.

What do the ISF, ICF, ICE and IST scoring indices measure?

They are four 0-to-10 scores computed from dozens of weighted factors: ISF rates financial health, ICF growth, ICE business quality and IST turnaround potential. They let you compare stocks from different sectors on a single scale.

What data does STKtracker analyze and how often is it updated?

It analyzes price, fundamental metrics (P/E, PEG, ROE, FCF, margins, debt), insider transactions (Form 4), earnings-estimate revisions and analyst consensus. Data is refreshed automatically for every stock in your list.

What are the automatic badges?

They are labels that classify each stock at a glance: 6 positive (Growth, Pull Back, GARP, Consensus, Insiders, Earnings Up) and 3 risk alerts (Value Trap, Dangerous Debt, Sell Consensus). Each badge is triggered by an objective formula over the stock data.

Can I track my real portfolio with STKtracker?

Yes. You can build a virtual portfolio with real-time P&L or connect your broker to track your real portfolio, with concentration analysis and historical performance versus benchmarks such as the S&P 500.

STKtracker offers a free plan and paid plans (Personal, Pro and Unlimited) that add more watchlists, stocks per list, badges, portfolio analysis and broker connection. You can start for free with no credit card.

How are the scoring grades calculated?

Each index combines dozens of fundamental factors, normalizes them to a 0-to-10 scale and weights them by importance (some factors carry more weight than others within each index). The result is a consistent, reproducible grade. The Methodology page explains which factors go into each index and their relative importance. If data is missing, only the available factors are weighted and the coverage is shown; below a minimum, the grade is not published and shows "n/a".

Why do some securities show "n/a" in the indices?

When a security is missing too much fundamental data, STKtracker does not make up a grade: each index only weighs the factors that have data (re-normalization) and reports its coverage. If coverage is insufficient, the index shows "n/a" instead of a misleading grade; with limited coverage it is flagged as "partial data". ETFs and funds always show "n/a" because they have no financial statements comparable to a company's.

Where can I learn to interpret the indices and badges?

The STKtracker Guides section has free articles explaining every key metric (ROIC, PEG, EV/EBITDA, operating margin, FCF yield, net debt/EBITDA, insider buying, value trap and more) and how each relates to the ISF, ICF, ICE and IST indices.

Does STKtracker provide financial advice?

No. STKtracker is an analysis tool for informational and educational purposes only. It is not financial advice and investment decisions are the sole responsibility of the user.

Operating margin: the number-one financial-health factor

Operating margin measures what percentage of sales turns into profit once production costs and operating expenses are deducted, but before interest and taxes. It is a direct x-ray of how efficient the business is.

How it is calculated

It is operating profit (EBIT) divided by total revenue. A 25% operating margin means that for every 100 euros sold, the company earns 25 euros from its core activity before paying interest and taxes.

Why it is so revealing

A high, stable operating margin usually signals pricing power (the company can raise prices without losing customers), cost control and a solid competitive position. When the margin expands year after year it points to an improving business; when it shrinks, it is worth investigating why.

What to watch

Compare the margin with direct competitors in the same sector.
A rising trend is worth more than a one-off high level.
Shrinking margins can foreshadow competition or cost problems.
Sectors differ widely: software has high margins; retail, low ones.

How STKtracker measures it

Operating margin is the highest-weighted factor (20%) in STKtracker’s Financial Health Index (ISF). Alongside debt, liquidity and profitability, it feeds a score that sums up each company’s financial soundness.
