Sources of stock market price data
Stock market price data is readily accessible from a number of web sites. Popular data sources include Yahoo Finance, Google Finance, and msn Money. The time span of historical data available from these sites varies considerably, from the last 12 months for msn, to more than 50 years for Yahoo.
The two sites with the greatest availability of data for download are Yahoo and Google. Both provide daily data for the Open, High, Low, Close, and Volume series. For major United States corporations, such as General Electric - Yahoo has daily data back to January 1962 and Google has data since 1970. msn, on the other hand, only has weekly data for last 12 months (sourced from Morningstar).
Both Yahoo and Google provide a download link, but Google disables the download feature when Australian data is accessed. In contrast, Yahoo does not have this restriction, and this enables the user to download the full data selection from Yahoo as a CSV file. In contrast, Google displays Australian data with a maximum of 30 rows per screen, and the user needs to copy and paste each screen of data, screen by screen. International price data, that is, price data from outside of the United States is supplied to Yahoo by Morningstar.
Other sites also provide snap shot price and other financial information. These include:
- Financial Review - markets data
- Barron's - market data center
- Bloomberg - markets
- Financial Times - markets data
- Reuters - global market data
- Wall Street Journal - market data
