Hi Joshua,
With the release of Optuma 2 we now have dividend-adjusted data available to display Total Returns. Open a chart of COMB and change the display from Price Returns to Total Returns and the chart will be adjusted, as per the chart on the right.
However, if the data does not update after changing the display then the adjusted historical data will have to be downloaded by clicking Download History under Actions (to download the adjusted data for the entire US exchange at once see Option 3 here).
