By reading the summaries, you can find out how much money you made as well as what were the investments that made the largest impact.
The overview summary also shows a simple table with all the gains and losses.
For the monthly summaries, each month is colored to indicate profitable months (which have a green background) and which months ended with a loss (which have a red background). The monthly summaries will also indicate which month is the high point (portfolio had the most value) and the low point (portfolio had the lowest value).
