Stock History
Select a publicly traded business or stock that plays in only one industry in which you have interest. Download the raw data on the company’s stock history.
Follow these steps to locate and download stock history from Yahoo! Finance:
Go to Yahoo Finance.
Search for and find the stock information of your chosen company. Remember do not use a company that plays in multiple industries.
Once you pull up the general data on the company, review the screen links throughout until you find the link for Historical Data. Click on the Historical Data link.
Then select the following settings above the table:
Select Time Period of one year.
Select “Historical Prices.”
Select Frequency as “Daily.”
Click Apply.
Click Download Data. Go to the bottom of your screen or your Downloads folder to open the Excel file you just downloaded. Open the Excel file. Check to be sure that you have enough lines to show the whole year. If not, reset the settings at the top of the Historical Data chart and try again.
Once you are sure that you have a year’s worth of data, save the Excel file.
Using the Excel file with the year’s stock data, conduct descriptive analysis as follows:
