I haven't even looked at this forum in a couple months. I check in and see this? Really?
Despite that one day blip - which is something you want to avoid in the market anyway - last month was the worst December for the stock market since the Great Depression. For the month, the Dow was down 8.7%, and the S&P was down 9%. Overall, 2018 was the worst full year since the financial crisis of 2008.
