About Daniel

Daniel covers the numbers every investor needs to be able to trust: what a position cost, what it is worth today, and how much it has really made. His guides explain realized and unrealized profit and loss, average cost, and how to measure your returns against the S&P 500.

He also turns the day's company and market news into plain answers for people who already hold the shares, and writes the side by side comparisons of PortfolioTrackr with other trackers and with the spreadsheet.
