If you are new to stock trading, the first thing you will hear of in your stocks trading basics is probably stocks technical analysis. And yes, yahoo is a very convenient way to get stock prices and charts to see the general pattern of performance over time. The thing I don’t get about technicial analysis is if theirs a pattern to the movement of the price of a stock than how do you account for surprise news coming out about a company that no one expects. This will affect the movement of a stock but if nobody knows about it ahead of time how can a trader plan for it. in other words the direction of the price of a stock is totally unpredictable in that case.

You can use your skills to locate pathfinders, research guides and other materials compiled by librarians to set you on the path to sources of historical stock pricing information. Entering a symbol produces a screen with basic current data and an option for historical quotes for that stock.
The tab for historical quotes appears near the top of the home page eliminating any confusion about where to go next. You also have the option to create a chart of activity: daily, weekly, monthly, quarterly, yearly, or more narrowly: 1 minute, 5 minutes, 15 minutes, hourly. These tracking charts, unfortunately, are only in chart form and there does not appear to be an option to simply list times and numbers.
The usual information is provided: open, high, low, close and volume and I was able to follow a sample stock back to 1988. At this site you can also get the prices and volume for specific times throughout the day and this information can be printed in clear columns for easy reading. Next take a look at my charts based on Yahoo Finance adjusted closing price data.
Many of the larger, well established corporations provide historical pricing information in their investor relations materials. Fee-based sources such as Dow Jones Interactive or Tradeline via Dialog also provide historical pricing information.
