earnings

are the Wall Street equivalent of report cards. And for investors, it's a smart idea to pore over the earnings report as assiduously as a strict parent examines junior's grades.

Take a company's

revenue

(the money collected from selling a service or a product), subtract the company's costs to make and distribute the item as well as expense items such as debt interest and taxes, and you get earnings (a.k.a.

profit

,

net income

and

bottom line

). Publicly traded companies in the U.S. are required to post earnings -- or, more precisely, financial statements, since some companies post losses instead of earnings -- every quarter. Most companies adhere to the calendar quarter, but some issue earnings based on their own fiscal calendars. (In addition to earnings, companies provide

earnings per share

by dividing earnings by a company's total shares outstanding.)

Because earnings are the best indication of a company's fiscal health, they are closely monitored on Wall Street. Before earnings are released, analysts issue

earnings estimates

for the companies they follow, and these estimates are compiled by earnings trackers such as First Call/Thomson Financial to determine a company's

consensus earnings estimate

. An

earnings surprise

occurs when a company's profit exceeds or falls short of estimates. Often, upside and downside surprises have a big impact on a company stock price. Earnings reports break out revenue and other measures of financial performance, and may also provide information about future prospects, which may move a stock.

Wall Street watches earnings to gauge a company's growth (or decline), and also uses earnings to determine a company's stock market valuation. Investors need to watch earnings as well because, as the business mantra goes, "Stock prices follow earnings."
