Data dictionary

The data dictionary is a searchable reference of every metric used across the Research Terminal and company pages, each with a plain-English definition and, where one applies, the formula. This reference explains what the page shows, how to search and filter it, and how to read a representative formula. It is open to Free, Pro Lite, and Pro accounts.

What it shows

A sticky search and filter card at the top, with a search box, category filter chips, and a live count of how many metrics match.
A table (cards on phones) listing each metric's Name, Definition, and Category. When a metric has a formula, it appears below the definition in a distinct formula style.
Category filter chips that group metrics into user-facing families: Company Profile, GNG Scores, Fundamentals, Quality and Health, Growth and Value, Dividends and Capital, and Market and Technical, plus an All option.
Sorting controls on the Metric name and Category columns.

Inputs

Search: free text that matches a metric name, its definition text, or its category. The default is empty.
Category: select one chip to show only that family, or All to show everything. The default is All.
Sort: select the Metric name or Category header to toggle ascending or descending. The default sort is by Category, ascending.

Outputs and how to read them

Metric name: the label used for the metric elsewhere on the platform.
Definition: a plain-English explanation of what the metric measures and how to interpret a high or low value.
Formula: shown only when the metric is computed, written in plain terms, for example Share Price divided by Earnings Per Share. For the platform's proprietary scores (such as Safety, Quality, and the GNG ratings), the entry describes what the score represents without exposing the scoring method.
Category: the family the metric belongs to, matching the filter chips.
Count line: the number of metrics currently shown out of the total set.

How it is calculated

The page itself is a lookup of definitions and formulas, not a calculator. Each entry's formula, when present, restates how that metric is computed. The three entries below are representative examples drawn directly from the dictionary. For every other metric, read the entry's own definition and formula in the dictionary; do not assume a formula that is not shown there.

Market capitalization

Market capitalization is the total market value of all of a company's outstanding shares.

market capitalization = share price × shares outstanding

In this formula, share price is the current price per share in dollars and shares outstanding is the number of shares the company has issued. For example, $50 per share and 200 million shares give a $10 billion market value. The figure reflects the current share price, so it moves intraday, and it does not account for debt or cash.

P/E ratio

The price-to-earnings ratio is how much you pay per dollar of current earnings.

P/E = share price / trailing EPS

In this formula, share price is the current price per share and trailing EPS is the trailing twelve-month earnings per share. For example, a $100 price and $5 of trailing EPS give a P/E of 20. The ratio is not meaningful when earnings are zero or negative.

PEG ratio

The PEG ratio is the P/E adjusted for expected earnings growth.

PEG = P/E ratio / annual EPS growth rate

In this formula, P/E ratio is the price-to-earnings ratio and annual EPS growth rate is the expected annual earnings-per-share growth in percentage points. For example, a P/E of 20 and a 25 percent growth rate give a PEG of 0.8, which can indicate value relative to growth. The ratio depends on a growth estimate that may not be realized.

Data and timing

The metric set mirrors the columns available across the Research Terminal and company pages, which are built from AlphaVantage market data and fundamentals, with Nasdaq quotes delivered through AlphaVantage. The dictionary's definitions and formulas change only when the platform changes its metric set, not on a daily refresh. The page presents on the order of one to two hundred metrics; the live count line shows the current total.

Use cases

Confirm exactly what a column on the Research Terminal means before you screen or rank with it.
Look up the formula behind a valuation or quality metric so you can interpret it correctly.
Filter to one family, such as Dividends and Capital, to learn the income-related metrics together.
Search a term you saw in an article or report to find its precise definition.

Limitations and disclosures

For the platform's proprietary GNG scores, the dictionary describes what the score represents rather than the full scoring method. The definitions and formulas inform how you read figures you may act on, so the standard information-only statement applies.

GNG Research provides equity research and educational tools, not investment advice. Nothing on the platform is a recommendation to buy or sell any security. Do your own research and consider your circumstances before making any investment decision.
