No loop is needed. For example, after putting the data into a Mathematica
compatible format, i.e.,
data = {{"1/2/01", "TBill", 0.67}, {"1/3/01", "SP", 0.78}, {"1/4/01",
"inv", 0.5}, {"1/5/01", "inve", 0.6}};
Simply doing
DateListPlot[data[[All, {1, -1}]]]
will generate a plot. There will be warnings since "1/2/01" could be Feb 1, 2001 or Jan 2, 2001.
