Risk disclaimer

Education, not advice

Everything on this site is general education about how markets, metrics and research tools work. None of it is investment, tax or legal advice, and none of it takes account of your circumstances, goals or finances. No page is a recommendation to buy, sell or hold any security. Before you make a decision that matters, consider speaking to a licensed professional who can look at your situation.

Trading and investing carry risk

Stock prices can fall quickly and by large amounts. You can lose some or all of the money you put in, and with margin, short selling or options you can lose more than you put in. Stop orders do not guarantee an exit price. Past performance of a stock, a strategy or a screen does not tell you what will happen next.

Taxes and costs

Trading has costs beyond commissions: the bid-ask spread, borrowing costs on margin or short positions, and taxes on gains, which depend on how long you held and where you live. None of the pages or calculators account for your tax situation.

Examples are hypothetical

Worked examples use invented companies and round numbers to show how a calculation works. They are not descriptions of real companies or forecasts of real results.

Calculators give estimates

The calculators do arithmetic on the numbers you enter. Their output is only as good as those inputs, and several inputs, such as growth and discount rates, are estimates by nature. Check any result before relying on it.

Data and third parties

The ticker tape shows quotes from a third-party service that may be delayed or unavailable. Metrics on quote pages and screeners can differ between providers, and rules and platform practices change. Check current rules with the SEC, FINRA or your broker. See also the terms of use and the editorial policy.
