The historical nav can be downloaded from MF sites and chart plotted with MS XL. MA's can even be added etc. They do tend to follow the trend of the index.
ETF's may be a better idea, they tend to outperform the underlying index and can be traded like stocks. I hear liquidity isn't good, but if bought and sold at the turn or major trends, holding for the longer term, it could be workable.
Hope this helps.
