I have a question about places like Yahoo Finance and Google Finance where you can make free portfolios to track stocks. It seems like the only price history you can view is the day’s gain and the overall gain from the time of purchase for the individual stocks, and then the same set of statistics for the portfolio as a whole. What I’d like to see is a line graph charting the performance of a portfolio much like you can do with individual stocks. But there doesn’t seem to be a way (so far as I know) to view your portfolio performance in aggregate like this. Does anyone know of a way?
You could use Google Spreadsheets to pull in the data and graph your portfolio that way.

The Motley Fool used to do what you’re asking about as well.
I suspect they still do.
That may be a way to do it. Longer than I’d like, but I could load up historical data for each stock in my portfolio, then come up with a weighted average representing the composition of my portfolio, and then plot the history of that weighted average.
Okay, disregard my advice.
Fool no longer has that.
I do this for a university fund and we just use do it the historical data + Excel + sorting way.
