jill and her co-mgr were replaced a few months ago. they did not do a good job at alpine over the last few years. here is some data from the 10/31/12 annual report on AOD (not AGD but performance was similar). this is the three year total return, per annum (dividends and capital appreciation).
AOD NAV up 2%
AOD stock price down 8%
S&P500 up 13%
MSCI all country world (ex-japan) up 9%
investment mgrs are evaluated on their ability to generate returns in excess of certain benchmarks. in this case they use the S&P500 and the MSCI all country world (ex-japan). as you can see they did not do well against those.
