Getting Started

How do I best use this site?

The NASDAQ site is optimized for viewing with Netscape's Navigator 6.2 and higher, Microsoft's Internet Explorer 6.0 and higher, and AOL 6.0 and higher browsers. In some areas of the site, we are making use of Java applets, RealAudio, Microsoft Windows Media Player (formally NetShow) and Adobe's Acrobat Reader. We try not to overdo plug-in/application requirements, but have decided that the above mentioned technologies are essential to enhance the user's experience of this site.

Our site layout has been optimized for 800 X 600 screen resolution, and we recommend you view the site at this resolution. Although any connection speed to the Internet will work, we recommend the use of a modem operating at a minimum of 56.6 bps. Higher speed modems will give you a more pleasant experience with download times.

You may find that a particular special effect loads and displays somewhat slowly the first time. These effects will, however, be "cached" in your system for future use, and will load much faster next time.

Tip: When printing pages with charts or graphs from the site, you should choose "landscape" orientation under page setup. For all other pages "portrait" orientation is fine.

How do I follow individual stocks over a period of time on your Web site?

Historical information on NASDAQ, AMEX, NYSE, and OTC Bulletin Board (OTCBB) stocks is available via the Quotes+ section. Enter the symbol of the stock you wish to view, choose Stock Chart, and then select the desired chart range from the drop down menue. Once you have selected the graph, you can click on the graph itself to receive the underlying tabular data or add a chart element for more detail. The following links provide samples of each chart element available:

What does NASDAQ stand for?

If this question were asked in 1971, the answer would be that NASDAQ—then spelled with all capital letters—is an acronym standing for National Association of Securities Dealers Automated Quotations. But this automated quotation system quickly matured far beyond its original quote-service roots, evolving into what it is today—a major world stock market. Indeed, what NASDAQ "stands for" is not nearly as relevant as what The NASDAQ Stock Market has become known for, namely pioneering screen-based technology and an abundance of growth companies.

Why isn't the Earnings Per Share (EPS) information always the same in the fundamental area and the analyst information area?

Our data vendor that provides information for the "Fundamental Area" takes the last four quarters of earnings reported by a company, and adds them up. The numbers they use are the fully diluted EPS; they use "as stated numbers" without including accounting changes. These numbers are adjusted for splits as needed. The EPS is sometimes called the Trailing Twelve Months by other vendors.

Our data vendor for the "Analyst Info" area uses the EPS from continuing operations. However, in some cases, analysts may sometimes exclude amortization of intangibles and non-cash stock compensation charges in their calculations (this is usually referred to as cash EPS).
