missing yahoo historic prices

[abnopanda]

It seems that some of the historical price data points are missing from Yahoo.

Example:
AVCA
Yahoo's historical prices only have data up til May 2008 (AVCA: Historical Prices for ADVOCAT INC - Yahoo! Finance) where Data is available through current day on Google Finance(Historical prices for AVCA (Advocat Inc.) - Google Finance)

Does anyone know anything about this or know of a work around? I would take Google's/MSN's data but they're lacking the "Adjusted Close" field which I need to calculate total return.

Wow, that's really weird. I use Yahoo to pull all my quotes and have never seen that. Yahoo has a tutorial on how they calculate adjusted close.

If you had to replicate all that logic, it might be a pain in the **** but it would definitely be possible. Actually, I just looked closer. AVCA has not had any splits or dividends since it became public so you can simply use the Close from Google or Yahoo. Close will be the same as Adjusted Close.
