No Bobby, in the sense that FinancialData gave you back EXACTLY what
you asked for!
Let me explain:
this is perhaps not so well known/interiorized by most users, but
FinancialData info page clearly states that:
"For historical data, properties such as "High", "Low", "Close" are
adjusted for stock splits, dividends and related changes."
So when Bobby asked
FinancialData["JANFX", {{2011, 2, 9}, {2011, 2, 11}}]
Mathematica gave back historical closing prices ADJUSTED for stock spits ,ect.
In order to get the RAW closing prices, one has to ask for
FinancialData["JANFX", "RawClose", {{2011, 2, 9}, {2011, 2, 11}}]
and indeed one gets....
{{{2011, 2, 9}, 10.38}, {{2011, 2, 10}, 10.36}, {{2011, 2, 11},
10.37}}
the famous 10.36$ paid by Bobby on Feb 10th 2011.
