Hello invest_newbie,
Let me summarize how we calculate the portfolios' performances on this site.
We follow our portfolios' returns the same way an index would be built. It means that all the capital is always invested (no cash) and that the stocks in the portfolio are weighted proportionally to their performance since on hold.
So, the way to allocate the dollars between 4 stocks in the portfolio is not 1/4 if the 4 stocks have not recorded the same gain in the portfolio. Also, if a sale brings the content of the portfolio down to 3 stocks, then the remaining cash is not left unused, but reallocated on the 3 stocks still in the portfolio.
So, it is quite tricky to recalculate our performances since inception without the help of a software. But let's say, over a month, it is possible to track back the figures that are published on the web site.
For more information, this thread explains in details and with some figures how the performances are calculated:
How do we calculate the portfolio performances?Here are also the two threads that explains how two virtual portfolios are managed:
Virtual $5,000 portfolioVirtual $50,000 portfolioAnd DCA is right, in those two threads, the performance given as the portfolio's performance includes unrealized gains. These threads are only two weeks old so there has been only one sell since inception.
I hope this reply helps you to understand better how we calculate our portfolios' performances. Do not hesitate to ask for more information.
