A grayed-out row means the stock has been sold, and the sales date and price are shown. Other rows mean a stock is still held and the Sold/Current price is the most recent close price for the stock.
Both simple total gain and IRR (internal rate of return), the best measure of the return of a series of investments over time, are shown. All transaction costs are ignored.
All stock purchases are in equal dollar amounts.
This is not a recommendation to buy or sell any stocks, but only to start some thinking about possible investment opportunities. You must do your own analysis to decide if any actions are in your own best interests.
