Use Wolfram|Alpha to Get Information on a Stock

    
Time series data, like a stock's closing price, is returned by Wolfram|Alpha as a list of pairs of dates and values:
Wolfram Language code: timeseries = WolframAlpha["MSFT closing price", {{"HistoryDaily:Close:FinancialData", 1}, "TimeSeriesData"}];
Wolfram Language code: Take[timeseries, -10]
Plot a time series of the data:
Wolfram Language code: DateListPlot[timeseries, PlotTheme -> "Business"]
