Quarter 4 2018 was one of the worst quarters in history. It happened right after most of the major movers completed their earnings reports. Nflix beat earnings but tanked 15% Apple decided to hide their numbers Nvda got caught on the bitcoin train etc.. etc.. All that happened but the whole market tanked. hard until Jan 2019. Now we have a potential cold war with China, Riots and re-election... So much uncertainty.
