Bernardi's argument is valid in general, but not in this particular case. It seems that this Janus fund is not traded the whole day long, but that only a closing price is issued every day, and all transactions are executed at that price. The solution to this mysterious price divergence is simple. Check the historical price series in yahoo: http://finance.yahoo.com/q/hp?s=JANFX&a=01&b=05&c11&d=06&e=2= 9&f11&g=d&z=66&y=66 (I hope the link comes out right, anyway check the historical price link on the fund's page in Yahoo finance ) For the date 10 Feb 2011 you will see that the price is indeed 10.36$, but in the rightmost column the ADJUSTED price is 10.23$, the same reported in FinancialData. It seems the the price of this Janus fund is adjusted daily for dividends/distributions and that FinancialData just reports the Adjusted price. So, at least in this case, FinancialData is correct
