The three most common sub-categories of sin stocks are alcohol sin stocks (companies that make and sell beer, wine, and spirits), tobacco sin stocks (companies that make and sell cigarettes), and gambling sin stocks (companies that offer gambling services, such as casinos).
Although these three are the “big three” of sin stocks, there are other sub-categories as well — weapons or conflict sin stocks, s*x or p*rn sin stocks, and the most recent addition to the list — marijuana sin stocks.
