The Investment Activity graph visually displays the market value for a specific holding or portfolio, based on the allocations made into the portfolio. The historic performance data graphed is extrapolated from the ending portfolio value based on the monthly returns.
The graph dates back 10 years. The returns for this graph are calculated by asset-weighting the monthly returns of the underlying holdings and thus reflect the pretax results an investor would have achieved by re-balancing the portfolio on a monthly basis.
Total Market Value reflects the total value of the portfolio allocations made into the portfolio.
