Using the FinancialData function in the Wolfram Language you can iterate over a list of standard ticker symbols and return various properties. Something like:
FinancialData[#, "High52Week"] & /@ {"AAPL", "MSFT", "GOOG"}
This will return a list of the values:
{134.54, 56.85, 789.87}
You can find more information on the FinancialData function here.
