I've found a new (to me) species of error in FinancialData. One example is the price of the following stock on Feb 10, 2011: s = "JANFX"; FinancialData["JANFX", "Name"] FinancialData["JANFX", {{2011, 2, 9}, {2011, 2, 11}}] "Janus Flexible Bond Fund D Shar" {{{2011, 2, 9}, 10.25}, {{2011, 2, 10}, 10.23}, {{2011, 2, 11}, 10.24}} As you see, FinancialData says the price was 10.23. But I BOUGHT the stock through Janus Funds on that day, and the price was 10.36. Moreover, if I go to Yahoo's interactive price chart for the stock at the following page, 10.36 is the price I find: http://finance.yahoo.com/echarts?s=JANFX+Interactive#chart3:symbol=janfx;range=ytd;indicator=volume;charttype=line;crosshair=on;ohlcvalues=0;logscale=on;source=undefined So... where are the errors really coming from? This is not an astronomically large price or a Missing["Not Available"] price; it's within 2% of the correct price. But it's wrong. These errors make it very difficult to trust FinancialData for any useful purpose. Bobby -- DrMajorBob at yahoo.com
