Key terms on this page

P/E ratio

Price divided by the last 12 months of earnings per share. A P/E of 20 means investors pay $20 for each $1 of yearly profit. It is only defined when the company is profitable.

Price-to-sales

Market value divided by the last 12 months of revenue. Useful for companies with little or no profit, but it ignores margins.

Form 4

The SEC form a company's officers, directors and 10% owners must file within two business days of buying or selling its stock.

Open-market trade

A purchase or sale on the exchange at the market price, paid with the insider's own money (code P or S on Form 4), as opposed to option exercises, grants or gifts.

Form 13F

A quarterly SEC report listing the U.S. stock holdings of every investment manager with more than $100 million. It is due 45 days after each quarter ends, so it shows positions with a delay.

Dilution

When a company issues new shares, each existing share owns a smaller piece of the company. Common sources: stock offerings, convertible debt and large stock-based pay.

52-week high / low

The highest and lowest daily closing price over the past year (about 252 trading days).
