In my dividend growth investing portfolio, the goal is to build a passive income from dividends. Currently, the strategy is to just buy and hold forever, but as I learn to better estimate stock value, some dividend stocks might be sold in favor of other dividend stocks :)
Portfolio heatmap shows how your stocks performed within one month - what are the winners and what are the losers for the month.
It does include new stock transactions, so the portfolio heatmap shows a change in stock value in your portfolio, not stock performance.
(Even if stock price decreases, you might see a positive value if you bought more stock)
