You can make as much, if not more, when the stock market goes down once you understand shorting. I by no means have a full understanding of how everything works but I am separated my investing (non-work related) into 3 sections. Long stock investments (buying and holding certain stocks for dividend payment and long time growth), Short stocks (watching trends and researching for stocks that I feel are on a downtrend and shorting), and options (this one is completely new to me and I am just starting to dabble in it)
