The losses that started with Asian markets opening continued as European and North American markets opened leading to "circuit breaker" trading halts as stock indexes fell faster than fiat market operators could deign to tolerate (archived). Italian markets have been hit particularly hard as the novel coronavirus has managed to thrive there leading to the quarantine of 15 regions.  In the past 20 years, only the reopening of the NYSE in the aftermath of 9/11 and October 23rd, 2008 rival the S&P 500 ETF's opening losses today. Sorry for your loss.
