Hi Pete,
Below is the macro :
Sub GetYQuotes()
Base01 = "http://finance.yahoo.com/d/quotes.csv?s="
Base02 = "&f=sl1d1t1c1ohgv&e=.csv"
sURL = ""
SymString = ""

LastRow = Cells(65536, 1).End(xlUp).Row

For i = 1 To LastRow
SymString = SymString & Cells(i, 1) & " "
Next i
sURL = Base01 & SymString & Base02
Workbooks.Open sURL
Set rngSource = Cells(1).CurrentRegion
x = rngSource.Rows.Count
y = rngSource.Columns.Count
With ThisWorkbook.Sheets(1)
Set rngDest = Range(.Cells(1, 1), .Cells(x, y))
End With
rngDest.Value = rngSource.Value
ActiveWorkbook.Close SaveChanges:=False
End Sub

You have to arrange your worksheet with no titles in row 1 and using
column A to type in your symbols
ORCL for Oracle, GE for General Electric ...

HTH
Cheers
