Can GoogleFinance access total return data?
At this time, Google Finance doesn't support historical return or dividend data, only share prices.  The attributes for mutual funds such as return52 are only available as real-time data, not historical.   Yahoo also does not appear to offer market return data including dividends. For example, the S&P 500 index does not account for dividends--the S&P ^SPXTR index does, but is unavailable through Yahoo Finance.
